05:21:03hardeepearHurts: no, the scramble code is a little different
05:22:43hardeepactually, i take that back, the scramble is the same... there are other differences though which will result in it not booting
05:24:24earHurts I've got a user telling me my recorder build doesn't work, but I can't load it on my fm.
05:24:45hardeepi can try it, what's the url?
05:25:55earHurtsHas anyonne managed to run the simulator under cygwin?
05:26:14hardeepearHurts: yeah, it works pretty well in fact
05:26:34hardeepalthough i prefer the win32 simulator because of the msvc debugger
05:26:34earHurtsdoes it require X?
05:27:02earHurtsfie on ms!
05:27:12hardeepearHurts: yeah, but you can use xfree86 provided with cygwin
05:28:48earHurtshardeep, on the build, see what menu->general settings->file view->chop file prefix gives you.
05:29:32hardeepi get the tree menus you mention in your docs
05:30:20earHurtsdoes the at/after work?
05:30:48hardeepthe options are there... let me see if they work as expected
05:31:56hardeepyeah, looks like they're working
05:32:32earHurtsyou were able to select at or after?
05:32:44hardeepyeah, and they worked as documented

05:33:21earHurtsok, if you now set chop to no, do your file manes dispaly normally?
05:33:52earHurtshnmmn. Thanks.
05:34:20earHurtsThis is contrary to Michael O'Quinn's report
05:34:42hardeeponly thing to note is that my settings had just been reset so the config block was fresh
05:34:57hardeepmaybe he had some bad settings laying around due to other patches
05:35:40earHurtsbnut he was using my build, which only has nmy patches.
05:36:09hardeepyeah, but he may have used a patched version before that updated the same config block areas
05:36:33hardeepwhich would've lingered around when he booted into yours
05:37:12earHurtsagain, thanks.

15:18:18Bagderdoes changing the time affect it?
15:21:09Stevie[FreedomPahowdy guys
15:24:24Stevie[FreedomPawhat's up
15:25:17Zagorwe're complaining, mostly :)
15:26:53Stevie[FreedomPawell does anyone know why the 8MB patch caps the buffer reads to 1mb?
15:27:26 Nick Stevie[FreedomPa is now known as Stevie[FP] (~whatsit2u@
15:27:27Zagorbeats me
15:27:44Stevie[FP]it seems to limit the usefulness of having 8mb
15:27:51Stevie[FP]unless you're seeking backwards a lot
15:28:07Bagderthat 1mb limit is not an absolute stop
15:28:18Bagderit only means it'll start playing before swapping all the buffer
15:28:30Stevie[FP]the code says
15:28:43Stevie[FP]amount_to_read = MIN(mp3buflen - mp3buf_write, amount_to_read)
15:28:46Stevie[FP]then, if MEM == 8
15:28:51Stevie[FP]i.e. 8mb
15:30:22BagderI know
15:30:23Stevie[FP]amount_to_read = MIN(0x100000, amount_to_read)
15:30:31Bagderbut it doesn't stop reading after that
15:30:39Bagderit is just a limit for this particular read
15:31:04Bagdersince filling the whole buffer at once takes too long time on 8mb units
15:31:13*Stevie[FP] writes a patch for this
15:31:48Bagderfurther down you'll see that it'll post another message to itself and then it'll read again
15:32:47Stevie[FP]ok, i c
15:39:43Bagderour set date function is a bit silly
15:40:04BagderI believe it get crazy when we read a very weird year
15:40:40BagderI'll fix
15:41:40dwihnoBagder: is it possible to do a %02in in a custom WPS? :)
15:41:51BagderI doubt it
15:42:06dwihnoBoo! ;)

15:46:39dwihnoI got an idea regarding the module loader today. How about enabling runtime modules for different remote controller interfaces?
15:46:56Stevie[FP]hey bagder
15:47:09Stevie[FP]New patch
15:47:24BagderI noticed
15:47:31Stevie[FP]how'd you notice that fast?
15:47:38BagderI subscribe to the list
15:47:48BagderI get all changes to all trackers
15:47:50Stevie[FP]there's a list that gets emails when someone submits a patch?
15:47:55Stevie[FP]ah, ok
15:47:58Stevie[FP]actually I plan to patch it more effectively, but for now I think this will suffice
15:48:25Bagderhi mbr
15:48:26Stevie[FP]what I think would be best is to remember the USB attachment
15:48:41mbrBagder: seen my patch for time/date setting?
15:49:19Stevie[FP]and if we're still attached by the time we read another key, we return SYS_USB_CONNECTED again
15:49:22mbrit fixes the messed rtc ram after power loss, also
15:49:55Bagderdoes it? do we always get 0xff then?
15:50:05***Saving seen data "./dancer.seen"
15:50:19mbrI think so ..
15:50:19dwihnoAny news about running Rockbox from ROM?
15:51:23Stevie[FP]dalnet needs a new routing team
15:51:32mbrday and month is also beyond the valid range
15:52:02Bagdermbr: you could make the check if(timedate[3] > 30) {}
15:52:05Bagderjust in case
15:52:20mbrI think the registers are set to 0xff as the ram used for settings
15:52:51Bagderbut the clock surely gets updated
15:53:17mbrThats why I used the year
15:53:25mbrBut yes, this may be a problem
15:54:25Bagdermbr: I think you should apply and commit that fix and now allow any year that is beyond 2030
15:54:31Bagdernot allow
15:55:02Bagderoh, and then you can remove my silly fix for >2030
15:55:09mbrAnd include a range check for all other values?
15:55:55BagderI guess so, as otherwise the code won't be happy, like when we get 3-digit seconds or minutes
15:56:11BagderZagor: here?
15:57:59Stevie[FP]I reserve the right to experience life to the fullest, and that only happens at 137:254:80 PM

21:12:20Zagordidn't look at the code though :-)
21:12:59quelsarukadiamas: are you here?
21:13:03Stevie[FP]it's actually a simple concept that I discovered (but didn't quite understand) back in the 8088 real-mode days, before I understood how the memory addressing worked
21:14:01Stevie[FP]address pins that aren't connected to anything useful are effectively ignored
21:14:06Stevie[FP]so if you have a 2MB chip
21:14:31Stevie[FP]address P, 2MB+P, 4MB+P, 6MB+P, 8MB+P, 10MB+P, etc. are all equivalent
21:15:29Stevie[FP]so I pick a memory address P, write a known value to it, then write a different value at address P+2MB
21:15:39Stevie[FP]if the value at P changes, we have a 2MB chip
21:15:48Stevie[FP]if it doesn't change, we must have an 8MB chip
21:16:17Zagori'd have expected a machine check exception...
21:16:47Stevie[FP]no, because the bus controller doesn't know
21:17:15Stevie[FP]if I remember right, the DRAM starts at 0x09000000
21:17:49Stevie[FP]anything from 0x09000000-0x09FFFFFF accesses the DRAM chip
21:18:52Zagorright, but what happens when there is no DTACK?
21:19:14Stevie[FP]I don't know what a DTACK is
21:19:30Stevie[FP]all I know is that, at least on the 2MB model, it works
21:19:57ZagorDTACK is Data Transfer Acknowledge
21:20:13Stevie[FP]I'm assuming that it works in a manner similar to the 128K chips on our old boards here (which, I'll grant you, are SRAM, not DRAM)
21:20:31Zagori haven't read those parts of the data sheets much, maybe it doesn't apply to the sh7034
21:20:32Stevie[FP]the upper address pins are not connected
21:20:55Zagorah, of course. i'm being silly.
21:21:13Zagordid you get someone to verify it on a 8MB yet?
21:21:14Stevie[FP]so the DRAM chip effectively access address modulo 2MB
21:21:17Stevie[FP]not yet
21:21:20Stevie[FP]the first version had a bug
21:21:54Stevie[FP]temporary brain failure
21:22:55Stevie[FP]I fixed it and uploaded a new version
21:24:58Stevie[FP]are there two rom chips?
21:25:50tracktheripperZagor what does the grid of 0's mean in one debug menu option?
21:27:55Zagorwhich menu option?
21:28:02ZagorStevie[FP]: no, just one
21:28:13Zagortea time, brb
21:28:49Stevie[FP]then I do not understand why there are two ROM regions
21:28:58tracktheripperhang on zagor
21:29:05Stevie[FP]plus, there's something called v5.03, I don't know what that is either
21:30:42tracktheripperZagor its Debug, View MAS regs and View MAS codecs
21:30:57tracktheripperI just wondered what the grid of 0s mean

21:33:58tracktheripperand what does Dump ROM contends do in the Debug menu?
21:34:44Stevie[FP]it creates 2 .bin files
21:34:52Stevie[FP]I don't understand how this CPU even boots
21:34:55tracktheripperwhat do they do?
21:35:20Stevie[FP]they don't do anything
21:35:23Stevie[FP]they're .bin files
21:35:30Stevie[FP]i can open them in UltraEdit for a nice hex dump
21:36:01tracktheripperand what does the grid of 0's do in view MAS codecs
21:36:10Stevie[FP]damned if I know
21:36:17Stevie[FP]I think it's just that most of the values are 0
21:36:25Stevie[FP]I think it should display more than 4 lines at a time
21:36:31Stevie[FP]since my FM can show twice that
21:36:47tracktheripperi thought they switch between 1 and 0 to indicate the MAS is working during MP3 playback
21:38:00tracktheripperwell im sure Bjorn and co knoiw
21:47:25hardeeptracktheripper: those are just the current values in the specified registers. You can see what each register refers to in the MAS datasheets (
21:48:20Stevie[FP]i don't get this

22:06:04tracktheripperohh right. Im sure the frogs who work for Archos can tell you
22:08:23tracktheripperarchos is a french company :-)
22:08:33tracktheripperor im sure Bjorn and co can tell u
22:10:03webmindanyone here know if usb2 is backwards compatible ?
22:10:15tracktheripperUSB2 is backwards compatible with USB 1.1
22:10:29Stevie[FP]webmind: pretty much all USB 2.0 devices can run as USB.11
22:10:31Stevie[FP]1.1 even
22:10:42Stevie[FP]i like the CPU's branch instruction mnemonic
22:10:47webmindk good
22:12:23tracktheripperWould the Archos work if u got a USP to parallel or serial lead?
22:13:05webmindtracktheripper, how do u mean ?
22:13:36tracktheripperthose cables that have a type A USB plug at one end and a parallel or serial plug at the other end
22:14:10tracktheripper"just in case all of your USB ports are being used...."
22:15:03tracktheripperZagor can I ask u something plz?
22:16:09tracktheripperI would love to see the option to reshuffle the playlist when it repeats. I use my Archos all day on random mode and its a pain manually reshuffling the list from time to time

22:30:34tracktherippercool even :-)
22:38:45[IDC]DragonI have disassembled and commented the Archos ROM bootcode, interesting things inside. Does anybody know if it's legal to publish that?
22:46:06Stevie[FP]hey IDC
22:46:28Stevie[FP]I found the glitch in my 8MB autodetection routine
22:46:39Stevie[FP]it should actually detect 8MB chips now
22:48:02[IDC]DragonHi Steve, I already saw that and repied. Yes, it works (and crashes).
22:48:20[IDC]Dragonreplied, I mean
22:48:57Stevie[FP]thats a bit different from what it did before (which was incorrectly determine 2mb)
22:49:00Zagor[IDC]Dragon: no it's not legal to publish the code. but you can publish discussion about it, and instructions how to extract/disassemble etc it
22:49:31Stevie[FP][IDC]Dragon: when does it crash?
22:50:07[IDC]DragonHello Björn! So I can tell what it does, and have to email it around?
22:50:22[IDC]DragonSteve: Whe roloing, as you said.
22:50:34Stevie[FP]it crashes when it ROLOs another build
22:50:45Stevie[FP]but when it's running itself it shouldn't crash
22:50:58Zagortreat the code as a book, then you'll know what I mean. you are allowed to publish excerpts and of course as much of your own comments as you like. you simply are not allowed to publish the entire code verbatim.
22:50:58Stevie[FP](actually it crashes when it ROLOs anything, even itself :-o)
22:52:46Stevie[FP]ok, it works!
22:52:50Stevie[FP]I did something right
22:52:55*Stevie[FP] marks his calendar
22:53:34Stevie[FP]ty :)
22:53:42Stevie[FP]if only I knew why it crashed when ROLOing
22:54:15[IDC]DragonDidn't went into the right code, I'd say.
22:54:38[IDC]DragonBjörn, are you into ROLO?
22:55:09[IDC]DragonSo, how does it work?
22:55:20Stevie[FP]do we read from the LCD status register at all?
22:55:35[IDC]DragonI always wondered how you exchange the code under your feet.
22:55:59[IDC]DragonLCD status register???
22:56:17Stevie[FP]yeah, if you do an i2c read instead of i2c write, it seems you get a status result
22:56:46[IDC]DragonIs that any good for 8MB? ;-)
22:57:38Zagor[IDC]Dragon: it's pretty simple, since the code only uses the first 200k. we simply copy the rolo code into a higher memory address and run it there.
22:57:47Stevie[FP]well, i'm glad the autodetection works
22:58:20ZagorStevie[FP]: um, i don't remember if we ever read the status
22:58:25[IDC]DragonBjörn: Then you have the other 200 k wasted? Is is all position independent?
22:58:27Stevie[FP]it doesn't look it
22:58:58Stevie[FP][IDC]Dragon: I think he means he copies the bootstrapping code into a higher memory address and loads the new image at the base address
22:59:15Zagor[IDC]Dragon: no, we link the rolo code for the high address. the we load the new .ajz into ~1MB, copy it back down to 0 and execute it
22:59:42[IDC]DragonAh, the rolo code, I see.
23:00:15ZagorStevie[FP]: actually we need to load to a temporary hi-ram buffer, since the disk code is in low ram
23:01:41Zagorlook in the linker control file (, you will see a section called .topram which is at the very top of the memory. that's where rolo is.
23:02:06Stevie[FP]from there a simple memcmp is in order?
23:05:31Stevie[FP]when we write to the display
23:05:34Stevie[FP]we write 8 bits at a time
23:06:00Stevie[FP]each 'page' is 8 pixels high
23:06:18Stevie[FP]so effectively we write 8 rows, then the thing wraps to the next column
23:06:43[IDC]DragonThat's all software bitbanging, right? I wonder why the display isn't a crawl.
23:06:51ZagorStevie[FP]: yes
23:07:04Zagor[IDC]Dragon: yup, all software. and all over a serial link!
23:07:27*Stevie[FP] notes that a freaky look would result from setting the base column address to '4'
23:07:38Zagorand it *is* a crawl, comparatively speaking... with a better link we could probably have done grayscales
23:07:49Stevie[FP]indeed =/
23:08:19[IDC]DragonNo SPI feature on those ports?
23:09:24[IDC]DragonHow about som optimizes assembler for that, running from IRAM?
23:09:43[IDC]DragonSPI it that serial link, I think.
23:09:45 Join LinusN [200] (
23:09:58[IDC]DragonHi Linus!
23:10:01LinusNyou can't read the LCD status register in serial mode
23:10:09LinusNonly in parallel
23:10:14Stevie[FP]well that rules that out
23:10:19Stevie[FP]somebody's been reading the logs :P
23:10:32LinusNno, i'm psychic
23:10:39Stevie[FP]somebody's psychic
23:10:42Zagor[IDC]Dragon: it already is assembler. feel free to optimise it :-)
23:10:44Stevie[FP]oh, guess what, Linus?
23:10:58[IDC]DragonHow about IRAM?
23:10:58Stevie[FP]I wrote something that actually works!
23:11:08LinusNStevie[FP]: you fixed ROLO?
23:11:10Zagor[IDC]Dragon: worth trying
23:11:17Stevie[FP]but the detection part works
23:11:35Stevie[FP]I don't have the tools and/or skills and/or knowledge necessary to debug the problem =/
23:11:52Zagoractually, it's already in iram :-)
23:12:00*Zagor checked the code
23:12:11[IDC]DragonBjörn: And that write function seems to get called very often, for every byte.
23:12:41[IDC]DragonMaybe it could take some more.
23:12:42LinusN[IDC]Dragon: there is room for optimization in the LCD code, but last time i tried, the LCD couldn't cope
23:13:02[IDC]DragonOh, that's another limit, agreed.
23:13:18LinusNmight have been a bug in my code of course
23:13:45[IDC]DragonHow fast can you clock it, are we close to that?
23:14:04LinusNi don't remember
23:14:32[IDC]DragonMaybe I'll measure it when it's open next time.
23:14:47LinusNdo so
23:15:26[IDC]DragonMay I change the subject on booting?
23:17:08LinusN[IDC]Dragon: ?
23:17:12[IDC]DragonI haven't done the real test (because it requires to pull the 3 LCD input lines low), but with a simulator I managed to "boot" from UART.
23:17:53[IDC]DragonMeaning, we could execute something without anything useful in flash.
23:18:08LinusNi see where you are heading
23:18:54[IDC]Dragon1st stage we can only load into IRAM, the DRAM is not initialized yet.
23:19:33[IDC]DragonA bit crammy in there. Do we have the 7032 with 8K or the 7034 with 4 K?
23:20:05[IDC]DragonAs I guessed, the other one has no ROM.
23:20:43[IDC]DragonThe ROM code is prepared for multi-boot, the LCD lines decide.
23:21:38[IDC]DragonIt grabs image "n" from a list. In the available firmwares these entries all point to the same block.
23:22:18[IDC]DragonScrambling is mandatory for such a block.
23:22:29LinusNwe need to find a way to do this without the LCD trick...
23:22:48[IDC]DragonChange the ROM, I'm afraid...
23:23:01LinusNwhat does it do if there is no valid image in flash?
23:23:22[IDC]Dragonit checks for the "ARCH" ID right at the start.
23:23:45[IDC]DragonIf that's present, it will blindly use whatever values it finds.
23:23:55Stevie[FP]what LCD trick?
23:24:19Zagorhas anyone compared the flashed version with the same file version?
23:24:20LinusN[IDC]Dragon: and what if it is no ARCH?
23:24:27[IDC]DragonIf there is no "ARCH", it will flash the red LED a couple of times and the sleep in coma.
23:24:33LinusNStevie[FP]: pulling the three LCD lines low
23:24:59[IDC]DragonPort B, bit 1-3 (not 0)
23:25:14Stevie[FP]and what does this do exactly?
23:25:33LinusNif you do this, the cpu will boot into a special debug monitor
23:25:35[IDC]DragonIt goes to a UART boot mode, expecting code from there.
23:26:00[IDC]DragonIt's not a monitor, just a very simple code.
23:26:52[IDC]DragonBut you can use it to trasfer "something" into the box and execute it. In my example, a flash programmer.
23:27:42[IDC]DragonLinus, the suspense goes on:
23:28:20[IDC]DragonThe image being descrambled from flash is quite small, about 9k.
23:28:50[IDC]DragonIt's not the final firmware.
23:29:02Stevie[FP]that's at 0x2000000 or whatever?
23:29:38[IDC]DragonInstead, this is your "debugger", in fact it seems to be a flash tool.
23:30:35[IDC]DragonI don't know how to operate it, just saw the strings in there.
23:31:30[IDC]DragonRemember the box "talking" with 115200 baud on power up? That's this tool. You can hold it with any char from a terminal.
23:31:48Stevie[FP]115200, now that's MY kinda serial speed
23:32:05[IDC]DragonBut then it wasn't responsive.
23:33:58Stevie[FP]do we have a quick reference table somewhere of what contraptions are mapped at what addresses?
23:34:39Stevie[FP]example: external DRAM at 0x09000000
23:34:44Stevie[FP]internal RAM at 0x00000000
23:34:52Stevie[FP]external ROM at 0x02000000
23:35:03[IDC]DragonLinus, please check your mail, I've sent you the files.
23:35:56[IDC]Dragoninternal RAM is 0x0FFFF000-0x0FFFFFFF
23:36:23[IDC]DragonYou can get all that from the SH CPU datasheets.
23:37:20Stevie[FP]internal ROM at 0x00000000
23:37:42[IDC]DragonYes, 64k from there.
23:37:56[IDC]DragonArchos is only using about 1.7k.
23:37:58Stevie[FP]but what's at 0x01 or 0x03?
23:38:10Stevie[FP]and, for example, where is the RTC chip, where is the FM chip
23:38:34[IDC]DragonCheck the code ;-)
23:38:34Stevie[FP]we've got 16 possible values
23:39:19*Stevie[FP] rather dislikes values written as 0x100000 or 0x2000000
23:39:38Stevie[FP]0x200000 and 0x2000000 look the same damnit
23:40:21Stevie[FP]after about 5, all strings of 0s look the same =/
