| 04:30:20 | Saratoga | Wiki says the pin out is onfi although I don't know how that was determined |
| 04:38:53 | dongs | < dongs> http://i.imgur.com/wh8KbTN.jpg i mapped out the flash chip, it does sorta look like x16 nand with a couple exceptions... |
| 04:45:16 | Saratoga | Sorry, missed that, should put it on the wiki |
| 04:46:00 | Saratoga | How did you map that? |
| 04:46:46 | dongs | looked at onfi pinout, saw that most of those pins are connected same way, vcc/gnd parts are obvious etc |
| 04:47:01 | dongs | what i'm saying is that pinout *does* look like standard nand, with a couple exceptions i marked on there |
| 04:47:39 | dongs | like it has CE2 conencted (pin8) but that one is not used in X16 mode |
| 04:47:43 | dongs | the only thing I can think of is that |
| 04:47:51 | dongs | liek 1gb (do those exist?) clips used x8 nand mode |
| 04:48:01 | dongs | and then something larger like 8gb would use x16 |
| 04:48:02 | dongs | or something |
| 04:48:12 | dongs | or maybe they just made it compatible with either one |
| 04:48:37 | dongs | but 34/35 which are NC officially connecting is weird... |
| 04:49:18 | dongs | and now looking at that die xray, that pin36 actualyl is connected to gnd which spreads across the entire chip, which would be gnd on x8 but NC on x16. |
| 04:49:29 | dongs | but the die pic shows it wired up as x16, at least all the pins are there |
| 04:50:46 | Saratoga | Not sure if this matters but I believe the nand is accessed as N banks of 2GB each |
| 04:51:11 | Saratoga | Or maybe 1 GB, been forever |
| 04:51:30 | dongs | Saratoga: do you know as32wahtever boot sequence? if I wanted to boot it over jtag, by loading some code, is there steps to go through first? the jtagunbrick shit says loading into 0x0, but thats mapped to ROM when I power my stuff up |
| 04:52:00 | dongs | if I jump to 0x0 and start executing from tehre, it runs, then gets stuck in a endless loop somewehre in 0x80004xxx or someshit |
| 04:55:04 | dongs | donno if internal memory needs to be setup first and bla bla |
| 05:00 |
| 05:05:25 | Saratoga | Iirc it starts executing ROM, sets up the nand and dram, and then loads the nand start into ram |
| 05:06:02 | Saratoga | The data sheet describes how to boot from various things, but evidently the Sandisk ROM is different then built in |
| 05:06:34 | | Quit atsampson (Ping timeout: 258 seconds) |
| 05:06:47 | Saratoga | Funman might remember more I never played with it much |
| 05:08:27 | Saratoga | A few people have looked at the ROM but I'm not sure it's ever been fully worked out |
| 05:09:18 | Saratoga | Possibly if it's already booted the memory map is setup wrong |
| 05:09:26 | Saratoga | I forget if we remap it |
| 05:09:27 | dongs | right, i think what i need to do is skip the nand stuff, just do initial boot to bring up PLL/etc, setup ram/whatnot if needed, load what would have been loaded from nand into ram and jump there |
| 05:10:01 | dongs | is v2 (clip+) AMS chip much different from the one that the datasheet exists for? |
| 05:10:08 | dongs | i.e. completely different memory map etc |
| 05:10:19 | Saratoga | Can you put a breakpoint in the mkamsboot preboot loader? |
| 05:10:28 | dongs | v1 datshet talks about extenral sdram and shit (I guess it could be stacked die) |
| 05:10:37 | dongs | my jtagged clip has dead nandflash |
| 05:10:51 | dongs | so I can only boot to rom or to code I put into ram, wherever that is |
| 05:10:57 | Saratoga | It does have a different memory map ( more iram and different hardware) |
| 05:11:12 | dongs | and datasheet to that isnt linked? i only found v1 thats hosted by keil or wahtever |
| 05:11:25 | dongs | http://www.keil.com/dd/docs/datashts/ams/as3525_ds.pdf < this |
| 05:11:27 | Saratoga | They all have dram, either external or stacked die |
| 05:12:14 | Saratoga | There's no data sheet for v2, it's a mix of the as3525 and as3531 and some random Sandisk stuff |
| 05:12:26 | dongs | fuckin great |
| 05:12:58 | dongs | ah, 3531 looks more like the v2 chip |
| 05:13:03 | Saratoga | People have unbricked a v1 device over JTAG many years ago |
| 05:13:12 | | Join atsampson [0] (~ats@cartman.offog.org) |
| 05:13:28 | Saratoga | But it was after a bad flash, and on the m200v4 I think |
| 05:16:25 | dongs | yeah , my flash is deader than BSD, so just reflashing it isnt gonna help. i scrapped around a random 4gbit nand i had laying around and soldered it on, in 'recovery' usb mode it does show up as 32meg disk but writing to it and reading back brings back zeros so its clearly not w orking |
| 05:17:08 | dongs | i guess its quite likely rom only supports setting up just a dozen chips that sandisk would use or something |
| 05:17:11 | dongs | assuming it even gets tehre |

| 05:20:26 | dongs | it just looks like standard arm vector table |
| 05:20:36 | dongs | cant be ram right awayt |
| 05:20:50 | dongs | maybe ROM that executes some junk and later becomes RAM after initialization/remapping |
| 05:20:52 | Saratoga | ROM ? |
| 05:20:54 | dongs | yerah |
| 05:21:03 | dongs | if i try changing 1st vector it doesnt take |

| 05:23:01 | Saratoga | Iiuc the default ROM (which is not quite what Sandisk is using ) should poll various hardware devices to figure out what to do |

| 05:23:24 | dongs | before sdram is brought up |
| 05:23:29 | Saratoga | So maybe if the nand doesn't respond it never sets up the ram |
| 05:23:33 | dongs | right |
| 05:23:53 | Saratoga | 320 KB on v1, 1MB on v2 |
| 05:24:08 | dongs | at which address tho? |
| 05:24:09 | dongs | remappable? |
| 05:24:21 | Saratoga | It's embedded DRAm of some kind, ams licensed it from tsmc |
| 05:24:37 | dongs | right, sram or whatever |
| 05:24:51 | Saratoga | It's slower, but yeah |
| 05:25:03 | Saratoga | Everything is remappable |
| 05:25:17 | dongs | how much of sdram tho? |
| 05:25:20 | Saratoga | We don't use virtual memory, but there is an MMU |
| 05:25:43 | dongs | 3531 datasheet says 512k sram |
| 05:25:56 | Saratoga | 2 or 8 MB depending on device, but sdram controller must be configured first |
| 05:26:14 | Saratoga | It's double that on the Sandisk hardware |
| 05:26:30 | dongs | i guess i can just keep writing rnadom values at every few megs into addres sspace until i hit where the ram is |
| 05:26:33 | Saratoga | It's not quite the same as either data sheet |
| 05:27:06 | dongs | does rockbox bootloader expect hardware to be already setup by OF boot? |
| 05:27:08 | Saratoga | Doesnt the data sheet specify the initial memory map? Probably that didn't change much |
| 05:27:11 | dongs | or can it do all the bringup itself |
| 05:27:25 | dongs | the v1 datasheet has, but its fucked up, ram wasnt working at that address either |
| 05:27:52 | Saratoga | Some stuff is setup already, but most things are reset by rockbox anyways |
| 05:29:13 | Saratoga | I'm not sure anyone has figured out what exactly the ROM does |
| 05:30:36 | dongs | well i could dump/step/disassemble/decompile it but without memory map or at least most periphral addreses map it would be annoying as shit |
| 05:31:03 | dongs | could probly look through what rockbox has figured out for peripherals like gpio/whatever else it touches |
| 05:33:22 | Saratoga | I think what you could do is setup the dram, load rockbox into ram, and then boot into it, but even then you'd be reset when you powered off |
| 05:34:07 | Saratoga | Unless you replaced the nand |
| 05:34:35 | dongs | right, but if that does work, and rockbox can format the internal nand (the 4gbit replacement), then things could go from there |
| 05:35:17 | dongs | but anyway if ROM is only looking for a handful flash device IDs and doens't setup anythign that's not in that list then its fucked anyway as it will never boot from anything else |
| 05:35:55 | Saratoga | I think if you got a new nand working, you could do the ams unbrick trick to rewrite it |
| 05:36:25 | dongs | which was what? booting in recovery mode and copying some .bin file over? |
| 05:36:37 | Saratoga | Yeah that could be a problem if it only works with a few chips |
| 05:36:39 | dongs | i did that, but readback was zeros |
| 05:36:47 | dongs | so clearly nothign was going into it |
| 05:37:03 | Saratoga | If it's working you get a whole bank of memory, 1 GB I think |
| 05:37:10 | dongs | oh, really? |
| 05:37:24 | dongs | well, 4gib would be 512megs but yeah |
| 05:37:25 | Saratoga | If nothing is working you get 32 or 4 MB on AMSv2 |
| 05:37:26 | dongs | i dont have anything bigger |
| 05:37:33 | dongs | yes, i get 32. |
| 05:37:59 | Saratoga | On v1 I think 32 (or 16?) Means it worked |
| 05:38:13 | dongs | i guess I could grab 32gbit nand somewehre and resolder it again |
| 05:39:18 | dongs | would probly fuckup my carefully planted jtag connection |
| 05:39:30 | dongs | http://i.imgur.com/51tHgIW.jpg < this |
| 05:40:57 | Saratoga | Nice |
| 05:46:28 | dongs | i really dont know. the flash pinout confuses me greatly |
| 05:46:49 | dongs | if it was some custom thing with SDIO controller on it, it wouldn't need all those pins. |
| 05:47:06 | dongs | technically in 1 bit sdio you only need 3 wires |
| 05:47:14 | dongs | clk, cmd, and d0 |
| 05:48:02 | dongs | i suppose they could have trolled everyone and put that interface into pins 34/35/38/39 or something |
| 05:48:07 | dongs | on those NC pins on the nand pinout |
| 05:48:23 | dongs | but i think thats pretty farfetched |
| 05:48:38 | dongs | but then why bother routing/connecting the rest of nand pinout |
| 05:50:42 | fIorz | sourcing flexibility somehow? |
| 05:50:48 | fIorz | but does sound wild indeed :-) |
| 05:50:59 | Saratoga | It's used in a lot of different devices (see Google), maybe it has multiple modes? |
| 05:51:17 | dongs | what is, the AMS chip? or that shitdisk weirdnand |
| 05:51:39 | Saratoga | Alternatively it could be normal nand, but why put an SD controller in hardware if the CPU has a nand controller anyway |
| 05:52:03 | Saratoga | The nand chips is |
| 05:52:04 | dongs | maybe they had some IP left over from making sdcards |
| 05:52:23 | Saratoga | They use it in USB sticks |
| 05:52:38 | dongs | then its gotta be just normal nand, eh? |
| 05:52:55 | dongs | maybe i should find my socket and try actualyl reading the sandisk part |
| 05:53:07 | dongs | at least to get chip ID or something, then it would be obvious its not some SD-controller based weird thing |
| 05:55:30 | dongs | but if that part is in usb sticks as you say... even less reasons for it to be internally SD-based.. |
| 05:56:33 | *** | Saving seen data "./dancer.seen" |
| 05:58:01 | Saratoga | Maybe they put the flash translation layer on the package and expose it to the USB bridge? |
| 06:00 |
| 06:05:55 | dongs | typical garbagecheap USB sticks are either nand or emmc, with single chip controller |
| 06:06:34 | dongs | dont see why they would complicate it any more by adding extra shit |
| 06:22:49 | dongs | Flash ID code: 45C79432 - SanDisk SDTNNMAHSM-004G - 4CE/Single Channel [MLC-8K] - |
| 06:22:52 | dongs | accroding to google |
| 06:22:56 | dongs | its standard nand.. hmm |
| 06:23:24 | dongs | i guess i gotta figure out how to get dram setup and load rockbox there. |
| 06:33:26 | Saratoga | So the SD logic is entirely on the ams chip? |
| 06:36:38 | dongs | yes |
| 06:37:08 | dongs | i dont know why EXTRA lines are connected on the nand side, but if you ignore those the chip IS accessible as standard x16 nand, at least electrically |

| 10:59:51 | dongs | pamaury: did you see my current blogging about deadsansa and figuring out if I can swap a generic nand flash into its place |
| 11:00 |
| 11:00:05 | pamaury | you use headers |
| 11:00:50 | pamaury | dongs: I read the logs quickly but I don't know much about sansas |
| 11:00:57 | dongs | ah okay. |
| 11:01:07 | pamaury | afaik, sansas use an sd+nand chip |
| 11:01:22 | dongs | well, i spent last 24 hours checking that its most likely not the case. |
| 11:01:47 | dongs | if there's a nand->sd translation layer, its in the SoC and not on the flash chip. |
| 11:02:10 | pamaury | really? odd |
| 11:02:27 | dongs | same chips are also in USB flash drives |
| 11:02:33 | | Join Strife89 [0] (~quassel@adsl-98-80-190-150.mcn.bellsouth.net) |
| 11:02:48 | dongs | and people have loaded htem into standard nand flash dumping devices and they have chip ID and everything liek stanard nand. |
| 11:03:05 | dongs | and the fact that pinout for it mostly matches (minus extra signasl on pins that should be NC), etc. |
| 11:03:34 | dongs | now its MAYBE possible that they put a 1bit SDIO interface on those NC pins, but that would be pretty unlikley as well as pointless, since they already routed and hooked up all of nand x16 connections as wel. |
| 11:04:11 | pamaury | then I guess you can try to swap it with a generic nand and see what happens, the small problem is that you have to make sure the sd->nand layer will recognize it |
| 11:04:29 | pamaury | it may be using nand ids, or some semi-standard commands to get flash info |
| 11:04:38 | dongs | right. thats where i'm at now. its swapped with a 512meg part, its not doing (much), so I need to load some stuff up that maybe at least pokes SD and try to see if it works or not |

| 11:05:31 | pamaury | Isn't there a jtag and/or a special usb mode where you upload a file and it runs? |
| 11:05:39 | dongs | jtag works fine |
| 11:05:54 | dongs | USB shows up as 31meg thing but reading back doesnt work = zeros, so its probly not getting written. |
| 11:06:19 | dongs | if I knew memory map i could at least load hello world into it that does some stuff and poke sd controlelr registers etc |
| 11:06:26 | dongs | to see if I can get some info of the new "512meg" flash. |
| 11:06:48 | pamaury | the memory layout should be partly documented in target/arm/as3525/app.lds and also in the as3525 datasheet (which partly applies to amsv2) |
| 11:07:04 | dongs | ok, lds thats better. lemme look for that |
| 11:07:07 | pamaury | you can google "as3525 datasheet" |
| 11:08:33 | dongs | yeah when i looked at t hat, IRAM wasn't where it said it was (i have clip+). |
| 11:08:35 | dongs | gonna look again |
| 11:09:42 | dongs | ah i havent tried at c100000. time to hook it up again and check |
| 11:09:45 | pamaury | also look at as3525.h and as3525v2.h |
| 11:10:33 | pamaury | in rockbox we use the mmu to remap the iram iirc |
| 11:10:51 | pamaury | there might also be some magic bits that move/remap the iram |
| 11:11:55 | dongs | yeah on reset 0x0 is ROM, since i cant modify it. |
| 11:13:20 | pamaury | you might want to look at as3525/memory-init.S also and I think I have a ROM dump with some analysis. It's fairly common to have a ROM disable/remap bit |
| 11:14:49 | dongs | hey cool |
| 11:14:52 | pamaury | if you look in system-as3525.c, there is a bit called CGU_ROM_ENABLE |
| 11:14:55 | dongs | ram at c10000000 does work |
| 11:16:04 | pamaury | also if you look at page 190 of the as3525 datasheet |
| 11:16:23 | pamaury | you'll see that address 0 has three overlapping regions: ROM, ExtMemIF and RAM |
| 11:16:24 | dongs | yea im there right now |
| 11:16:34 | pamaury | depending on the Remap and IntBoolSel |
| 11:16:43 | dongs | k, i can put code into c1000000, so i could probly go from there |
| 11:17:14 | pamaury | ExtMemIF you be there if you boot from NAND I guess. And Remap is in CCU_MEMMAP |
| 11:17:34 | pamaury | (assuming it applies to amsv2) |
| 11:17:52 | pamaury | (page 116) |
| 11:18:32 | pamaury | so something like |
| 11:18:32 | pamaury | *(unsigned long *)0x0xC8100008 |= 2 |
| 11:19:02 | dongs | its 2 now |
| 11:19:12 | dongs | ccu_memmap is the register that controls remap? |
| 11:19:31 | pamaury | apparently |
| 11:21:08 | pamaury | you mean it was already 2 or you changed it to 2 ? |
| 11:21:21 | dongs | was at 2 |
| 11:23:08 | | Quit rela_ (Quit: Leaving) |
| 11:23:24 | | Join rela [0] (~x@pdpc/supporter/active/rela) |
| 11:25:01 | pamaury | give me a sec, I'll just have a quick look at the rom dump I have, it must remap the iram I think |
| 11:25:38 | dongs | after reset, PC is at 0 and it starts tehre. |
| 11:27:08 | pamaury | the very first thing the ROM does is to setup the mmu and it uses nonstandard bits |
| 11:27:24 | pamaury | sorry, it disables the mmu my bad |
| 11:28:30 | pamaury | actually the first thing it does is to jump at 0x80000000 |
| 11:28:50 | dongs | that seems to match with what im seeing |
| 11:29:01 | dongs | if i let it boot, it gets stuck in endless loop around 80004xxx or so |
| 11:29:08 | dongs | shortly after |
| 11:29:22 | dongs | o yeah |
| 11:29:33 | dongs | jumps to 80000D1C |
| 11:29:44 | pamaury | try to write 1 to CCU_REMAP |
| 11:29:51 | pamaury | that's what the ROM does for some reason |
| 11:30:01 | dongs | to C8100008 ? |
| 11:30:23 | pamaury | yeah |
| 11:30:29 | dongs | its '3' now. |
| 11:30:37 | dongs | and |
| 11:30:39 | dongs | ram is at 0 now |
| 11:30:51 | dongs | with my 0xDEADF00D still present |
| 11:30:51 | pamaury | so ram is working now ? |
| 11:30:56 | dongs | at 0, yes |
| 11:31:09 | dongs | before it was at c1000000 |
| 11:31:20 | pamaury | out of curiousity, can you try to see what is at 0x81000000 ? |
| 11:31:34 | dongs | alias of ram :) |
| 11:31:52 | pamaury | ah yeah the datasheet it's also an alias |
| 11:31:53 | dongs | same deadf00d stuff. |
| 11:32:03 | pamaury | good, so you found the ram remap bit |
| 11:32:35 | dongs | now can i load some bit of rockbox into that 0-ram and make it do something? :) |
| 11:32:42 | dongs | some bootloader part maybe? |
| 11:32:50 | pamaury | you want to load the bootloader |
| 11:33:33 | pamaury | although I have to say I don't know if you can plain load the .bin file produced by the compilation or if you need to patch the OF and load the patched thing |
| 11:33:55 | dongs | OF is liek 15megs tho |
| 11:33:58 | dongs | which part is bootloader |
| 11:34:12 | dongs | i probably have both patched and normal version |
| 11:34:53 | fIorz | pamaury: thx for the hint about the FM clock, BTW, it's indeed clocked by the 32 KiHz RTC crystal, and that one was ~ 0.4 % lower than what it should be, swapped it for a non-defective part, and stations are where they belong now, and stereo sounds acceptable as well :-) |
| 11:37:14 | pamaury | dongs: I don't know much about boot process, my guess is that the entire OF is flash to nand but the first N kB are the the bootloader and are loaded to RAM, and then it loads everything else. There must be some info on the wiki or in the code |
| 11:37:27 | dongs | right. |
| 11:37:32 | dongs | gonna poke around that for a bit |
| 11:37:33 | pamaury | in rbutil/mkamsboot for example? |
| 11:37:53 | pamaury | I know we use a decompressor |
| 11:37:58 | pamaury | because of the size |
| 11:38:03 | dongs | oh hm |
| 11:38:19 | pamaury | I think we take OF bootloader + rockbox bootloader, and compress them to squeeze them in the required space |
| 11:38:40 | dongs | ah theres some comments inside mkamsboot |
| 11:39:26 | pamaury | if you look at mkamsboot/dualboot/dualboot.S |
| 11:39:57 | pamaury | you'll see that it enables peripherals to read a key, then select either ucl compressord rb or of |
| 11:40:03 | freesoftware | do you think a 128GB chip will work? |
| 11:40:06 | pamaury | then decompress and run |
| 11:40:34 | pamaury | so my guess is that if you compile a rockbox bootloader for your device (clip+ ?), take the resulting bootloader.bin file and upload it at 0, it should work |
| 11:41:02 | pamaury | freesoftware: I'm missing some context here |
| 11:41:14 | dongs | freesoftware: havent seen any that ican actualyl buy in tsop48 |
| 11:42:14 | freesoftware | dongs build a BGA->TSOP board |
| 11:42:19 | dongs | plz. |
| 11:43:48 | dongs | pamaury: doesnt rokcboxutility pull bootloader.bin from somewehre? |
| 11:47:32 | pamaury | dongs: it pulls a scrambled version yes, give me a minute |
| 11:47:50 | pamaury | which device do you have ? |
| 11:47:55 | dongs | clip+ |
| 11:48:03 | pamaury | http://download.rockbox.org/bootloader/sandisk-sansa/clipplus/bootloader-clipplus.sansa |
| 11:48:30 | pamaury | this is NOT the raw binary, it has a small header (8 bytes). You need to remove the header because uploading that to the device |
| 11:49:10 | dongs | hm that looks like it might actually work |
| 11:49:17 | dongs | i see short jump offset to 0 |
| 11:49:19 | dongs | ok lets see |
| 11:51:01 | dongs | hmm no, that doenst look right |
| 11:51:09 | freesoftware | i hope things will be easier for me when my flash dies |
| 11:51:13 | dongs | ks like it might actually work |
| 11:51:15 | dongs | err |
| 11:51:17 | dongs | 00000000: 00 00 EA 20 RSCCS R10, R0 |
| 11:51:25 | dongs | first instruciton is this? thats wrong |
| 11:51:31 | dongs | should be some kinda vector table or something at start i guess |
| 11:51:44 | freesoftware | probably in like 2 years because chinese and database refreshes |
| 11:52:34 | pamaury | dongs: give me a minute, I might have been wrong about the header then |
| 11:52:58 | dongs | lemme load this up in real debugger and see if tehres better asm nearby |
| 11:54:02 | dongs | hm nope it all looks pretty shit, wonder if header was less than 8 bytes |
| 11:54:34 | | Join paulk-collins [0] (~paulk@gagarine.paulk.fr) |
| 11:54:49 | pamaury | no, the first 4 bytes are a checksum |
| 11:55:03 | pamaury | the next 4 bytes are a string "cli+" |
| 11:55:14 | dongs | yes |
| 11:55:17 | dongs | and next 3 bytes are useless too |
| 11:55:18 | pamaury | for me it looks ok |
| 11:55:23 | dongs | EA 20 00 00 looks like maybe valid arm |
| 11:55:39 | dongs | oh oops |
| 11:55:39 | pamaury | it's a valid jump |
| 11:56:24 | dongs | nice, jtag died |
| 11:56:28 | dongs | so at least getting somewhere :) |
| 11:56:28 | dongs | oh. |
| 11:56:31 | dongs | it powered off |
| 11:56:42 | *** | Saving seen data "./dancer.seen" |
| 11:57:16 | dongs | hmm |
| 11:58:11 | pamaury | it is possible that the code expects some init done by the rom |
| 11:58:34 | dongs | time to try gain |
| 11:58:35 | dongs | right |
| 12:00 |
| 12:01:06 | dongs | hmm no |
| 12:01:07 | dongs | damn |
| 12:01:12 | dongs | 1st jump goes to crap code |
| 12:02:45 | dongs | pamaury: 1st code jumps to 0x4001c, yeah |
| 12:02:47 | dongs | ? |
| 12:03:02 | dongs | but there is just trash, ANSDEQ/0 filled shit |
| 12:03:07 | pamaury | dongs: it jumps to 0X20 |
| 12:03:16 | pamaury | at least that what I see when I disassemble the file |
| 12:03:47 | dongs | from waht offset? |
| 12:03:50 | pamaury | 0 |
| 12:03:57 | dongs | you mean minus the header? |
| 12:04:00 | pamaury | yes |
| 12:06:53 | dongs | ok, yeah. |
| 12:06:59 | dongs | as soon as i jump and run that, it powers off. |
| 12:07:03 | dongs | hmm. |
| 12:07:20 | pamaury | can you step through the code ? |
| 12:07:25 | dongs | yeah |
| 12:07:49 | dongs | not until power off part tho.. only tried few instructions. trying to figure out how to make it properly load in debugger and not just cli stepping |
| 12:08:46 | pamaury | the first executed instructions should be: |

| 14:18:46 | pamaury | however I *think* that rockbox usb only exposes the user part of the disk, you can't use it to reflash the OF (which you need to to reflash the bootloader) |
| 14:18:47 | dongs | well |
| 14:18:48 | dongs | kinda |
| 14:18:55 | pamaury | for that you might need a custom build |
| 14:19:03 | dongs | pamaury: but its showing up as 1.3tb drive |
| 14:19:12 | dongs | i guess because tehre's absolutely no partition/etc info on the flash |
| 14:19:15 | pamaury | interesting... |
| 14:19:16 | dongs | wondering what i should do with it |
| 14:19:28 | pamaury | can you read/write from/to it ? |
| 14:19:35 | pamaury | (using dd) |
| 14:19:42 | dongs | yeah i considered trying |
| 14:20:32 | pamaury | I think that's the first step |
| 14:20:44 | pamaury | making sure the nand works (and persists accross boots) |
| 14:21:00 | dongs | tryin to find dd.exe that does raw drives |
| 14:21:10 | pamaury | if it works, we should do a special build to give full access to the storage and reflash the bootloader |
| 14:21:18 | dongs | yes |
| 14:21:20 | pamaury | are you using windows ? |
| 14:21:46 | dongs | got it, i had one that does raw devices |
| 14:22:26 | dongs | ok, reading = all zers, lemme write some random trash to it |
| 14:22:29 | dongs | and see if i get anything else back |
| 14:23:18 | dongs | damnit |
| 14:23:18 | dongs | nope |
| 14:23:28 | dongs | pamaury: read back is zeros |
| 14:23:31 | natanelho | pamaury can u help me? |
| 14:23:57 | natanelho | my clip zip wont boot up... |
| 14:23:59 | dongs | i guess ill try back when I get 4gb flash |
| 14:24:10 | dongs | 512m is probly not working for ~reasons |
| 14:24:38 | dongs | < dongs> http://i.imgur.com/3kCGEob.png < does that drive serial look like something rockbox would set? |
| 14:24:48 | pamaury | natanelho: did you try to hold power for 20sec ? |
| 14:24:49 | dongs | what's it based on i wonder |
| 14:25:12 | natanelho | yea |
| 14:25:30 | natanelho | it forces shut down |
| 14:25:52 | pamaury | natanelho: and nothing happens when you press power ? What happens if you plug the usb cable ? |
| 14:26:19 | dongs | *PANIC* mount: 0 |
| 14:26:22 | natanelho | it does *some*thing when I press power button |

| 14:26:37 | pamaury | dongs: given the wrongly reported size, it is likely the sd to nand layer doesn't like your flash or gets confused |
| 14:26:45 | dongs | right |
| 14:26:53 | natanelho | I loops in "boot 4.0" |
| 14:27:09 | natanelho | it* |
| 14:27:13 | | Quit dfkt_ (Client Quit) |
| 14:27:26 | pamaury | you mean it prints boot 4.0 and does nothing ? or it reboots in a loop ? |
| 14:28:01 | natanelho | pamaury: it prints boot 4.0 and does nothing, for really long time |
| 14:28:11 | natanelho | like till the battery drains |
| 14:28:28 | natanelho | or for a week if left in charger |
| 14:28:39 | dongs | pamaury: ok, cool, so it is booting consistently now with just loading image and adjusting memory remap and jumping to pc=0 |
| 14:29:00 | dongs | power down was due to current spike and psu limiting it. |
| 14:29:14 | dongs | now i just have to get new flash into it . |
| 14:29:26 | dongs | and fix bootloader to expose entire flash area (if it works) |
| 14:29:43 | pamaury | dongs: good, so yeah you need a new flash I guess. It's hard to help on this part, this is completely undocumented |
| 14:30:18 | pamaury | to be honest I am really surprised that the FTL is done in the soc, because that would mean either a third hidden process or a very dumb FTL |
| 14:30:38 | pamaury | also it's not described in the AS3525 manual |
| 14:30:45 | dongs | yep, hardware part I can handle. ill get soem 32 and 64gbit nand in the next few weeks to try out |
| 14:31:07 | pamaury | dongs: what is the part number of the original flash ? |
| 14:31:14 | dongs | pamaury: well its just an IP core, i dont know why they would go nand->SD maybe for programming easy purposes? who knows. |
| 14:31:21 | dongs | its.. sec |
| 14:31:26 | pamaury | natanelho: if you plug usb, do you get a usb driver ? |
| 14:31:31 | dongs | i only have 4gig ones |
| 14:31:37 | dongs | SDTNNMAHSM-004G |
| 14:31:42 | pamaury | dongs: SD is *much* easier |
| 14:31:51 | pamaury | dongs: is it from sandisk ? |
| 14:31:55 | dongs | im gonna get MT29F32G08CBADAWP and MT29F64G08CBABAWP |
| 14:32:01 | dongs | yeah |
| 14:32:04 | natanelho | pamaury: no |
| 14:32:08 | * | pamaury pulls his sandisk flash part decoder |
| 14:32:23 | dongs | according to internet its 32nm MLC flash. |
| 14:32:36 | pamaury | dongs: did you find the specific datasheet ? |
| 14:32:42 | dongs | nope not at all |
| 14:32:48 | dongs | the fact that sandisk got bought by WD doenst help |
| 14:32:49 | pamaury | natanelho: that's a bad sign |
| 14:33:14 | dongs | pamaury: he gets USB drive if he holds left or center, down |
| 14:33:26 | natanelho | pamaury: it does show something when I hold center button while connecting the usb to linux |
| 14:34:48 | pamaury | natanelho: if you hold left on boot (without usb), do you have a working device with the original firmware ? |
| 14:35:04 | natanelho | no |
| 14:35:09 | natanelho | green screen |
| 14:35:19 | pamaury | dongs: is there any other part on the pcb? |
| 14:37:55 | dongs | you mean? |
| 14:38:59 | pamaury | some device have a discrete IC that does sd <-> nand |
| 14:39:05 | dongs | ah, no |
| 14:39:11 | dongs | clipplus is just that |
| 14:39:18 | dongs | nand, SD socket, and AMS |
| 14:39:45 | dongs | i dont find it particularly TOO crazy that nand would be accessible as SD to firmware. |
| 14:40:02 | dongs | honestly I'd find it more crazy if sandisk did special SDIO-only "flash" ICs that only worked in their hardware |
| 14:40:07 | dongs | that seems liek a waste of resources |
| 14:40:17 | natanelho | pamaury: when I hold center and plug in usb it shows up on pc as media device, and shows 3.9 gb but then doesnt open |
| 14:40:21 | pamaury | that's very unusual to have it in the soc though |
| 14:40:42 | pamaury | natanelho: it seems to suggest a potentially bad flash |
| 14:40:56 | natanelho | pamaury: and that means..? |
| 14:41:04 | dongs | i have the original flash in a socket, but I gotta find my devboard where I can try bringing it up to the point of at least reading nand flash ID byte |
| 14:41:43 | dongs | wont happen today |
| 14:42:24 | dongs | anyway, if it returns some ID byte that means its basicalyl standard nand and should be able to be replaced, unless the hardware flash>sd translation layer specifically blacklists devices that arent sandisk |
| 14:42:24 | pamaury | dongs: yeah that would be the ultimate test |
| 14:42:41 | dongs | but google says it does return an id, etc |
| 14:42:49 | pamaury | natanelho: that means you device is close to dead unless you swap the flash, something that dongs is trying to do |
| 14:43:15 | natanelho | pamaury: no way to softmod? |
| 14:43:19 | pamaury | dongs: the problem is that there is no real standard to get nand info |
| 14:43:25 | dongs | eh, sure tehre is |
| 14:43:31 | pamaury | the info you get in the last byte is far from being enough |
| 14:43:45 | dongs | like 0x90 for read ID or whatever |
| 14:44:01 | natanelho | isnt it some problem with installing rockbox wrongly or something? |

| 14:45:21 | pamaury | natanelho: if you had rockbox installed and previously working, that seems unlikely |
| 14:45:21 | pamaury | also if you cannot even reach usb mode in the original firmware, you have no way to reflash |
| 14:46:15 | natanelho | I thought some linux magic code will save me :-< |
| 14:46:25 | dongs | pamaury: i donno, readID looks solid for knowing its nand and not some weird shit. cuz if it actually responds to that then its decided. |
| 14:47:23 | dongs | also, the same 004G IC has been used in USB flash drives |
| 14:47:37 | pamaury | natanelho: can you pastebin the dmesg output of when you plug it in usb ? |

| 15:06:22 | dongs | natanelho: it involves things like .. http://i.imgur.com/51tHgIW.jpg |
| 15:06:40 | natanelho | because if you are right, we can solder a huge NAND in place of the 4gb right? |
| 15:07:03 | dongs | not "huge" . nobody is making tssop nand anymore |
| 15:07:08 | dongs | its all bga for high capacity |
| 15:07:34 | dongs | 64gbit is max you can get |
| 15:07:46 | natanelho | and thats a lot... |
| 15:08:00 | natanelho | wait, megabit or megabyte? |
| 15:08:05 | dongs | bit |
| 15:08:07 | dongs | so 8gb. |
| 15:08:17 | dongs | i.e. the max that was in sansa clip+ |
| 15:08:27 | natanelho | so sandisk offered the largest possible memory:-< |
| 15:08:46 | pamaury | natanelho: try running fsck |
| 15:08:52 | natanelho | whats that |
| 15:08:56 | pamaury | sudo fsck -a /dev/sdc |
| 15:09:03 | pamaury | it will try to fix the file system |
| 15:10:06 | dongs | k. still comes up as 1.3tb after soldering, im 99.999% sure the connections are solid |
| 15:10:15 | dongs | will try again when i get 4/8gib chips. |
| 15:10:21 | natanelho | I think sdc is my flash drive, which runs the linux |
| 15:10:51 | natanelho | pamaury: will it damage it? |
| 15:11:41 | pamaury | natanelho: no |
| 15:11:49 | dongs | pamaury: i think most interesting would be stepping through bootloader wehre it initializes the SD layer and stuff and see error/return codes there |
| 15:12:15 | pamaury | natanelho: based on your dmesg output, sdc is the rockbox drive |
| 15:13:13 | pamaury | dongs: rockbox panics on sd error for the internal storage |
| 15:13:20 | dongs | mhm |
| 15:13:28 | dongs | you mean *PANIC* mount: 0? |
| 15:13:32 | dongs | thats what i get when i remove usb :d |
| 15:13:51 | dongs | why doent it panic earlier tho when i plug usb in? |
| 15:13:56 | pamaury | that's normal :-p No you would gte *PANIC* sd init -9 |
| 15:13:56 | pamaury | for example |
| 15:14:04 | dongs | ah |
| 15:14:20 | natanelho | fsck says "* is missing, cant fix yet" and stil lists a lot of my files, WTF |
| 15:14:20 | pamaury | mount panics because it cannot find a valid filesystem on the driver |
| 15:14:44 | dongs | hopefully its just because this ancient 512megabyte nand chip is just junk |
| 15:14:49 | pamaury | natanelho: did you remove your drive without safely ejecting ? |
| 15:14:51 | dongs | and it will just work(tm) with 8gib |
| 15:15:13 | natanelho | pamaury: maybe a few years ago, |
| 15:15:27 | natanelho | when it last worked |
| 15:15:51 | natanelho | I didnt touch it since, and I dont remember the cause of the problem |
| 15:16:43 | natanelho | pamaury: does it mean its possible to fix it? |
| 15:17:39 | pamaury | natanelho: if you don't care about the files currently on the device, I would say just reformat |
| 15:17:54 | natanelho | the command still runs |
| 15:18:05 | natanelho | how much time will it take? |
| 15:18:16 | natanelho | I care about them somewhat |
| 15:18:28 | pamaury | natanelho: ok, then wait until the command finishes |
| 15:18:45 | pamaury | it might take a while, depending on how broken your filesystem is |
| 15:18:50 | pamaury | fsck cannot fix all problems |
| 15:19:01 | natanelho | estimate? no? |
| 15:19:53 | natanelho | if its more then 5 hrs I wont bother... |
| 15:21:19 | natanelho | how bad could removing w/o safely ejecting a usb be for the device? |
| 15:21:24 | natanelho | like, deadly? |
| 15:21:47 | pamaury | not for the device, but your filesystem may end up corrupted and you may need to reformat, in the worst case |
| 15:25:39 | natanelho | theres a setting in windows that I might have touched, something along the lines of "make the device able to be removed w/o safely ejecting or use the old method (which is faster?)" AFAIK |
