00:11:35kugelwell, it's a macro expanding to our fdprintf (which takes a file descripter, not a FILE * stream). fprintf is called only stderr which is mapped to an fd instead
00:12:26Bagder... from before it was in the plugin.h one might presume

00:27:24RandomInsanoSo, telechips bootloader, doesn't seem to work so good. Built iAudio 7 bootloader, modified the main() function to just change GPIO port C, but I have zero response on those pins. Do I need to do anything with bootloader.bin other than use tccboot?

00:29:32RandomInsanoMy telechips CPU is a newer version of the 77X series from what I've compared in the spec sheets, with the IO addresses on the 8200 being remapped so many bits higher (0x80003020 for port C instead of 0x80000320 in the 77X series)

00:32:21Blue_DudeI want it to ... behave!
00:32:58Blue_DudeI don't think it's right to go with a different architecture just because the sim doesn't act like the target.

00:39:11Blue_DudeIt doesn't behave like a real DMA ISR callback so I'm kinda screwed.
00:42:42Blue_DudeAll this begs the question: if it needs a workaround to get the sim to work, is it worth doing at all?

00:43:43saratogaBlue_Dude: did you ask the SDL people about it?
00:44:18Blue_DudeOne possible solution is a way to get the sound.c driver to sleep for a tick or so. But I tried it and it bombed. I think sleeping that thread was a bad idea.
00:44:45saratogaRandomInsano: are you sure you've got everything linked correctly for the new CPU?
00:44:46Blue_Dudesaratoga: not yet. I spent a good part of the day away from the internet trying to get it to work.
00:45:33Blue_DudeAnd it seems to be an SDL issue. Maybe I just don't know enough about it to get it to behave. Or maybe it's a Cygwin thing. :(
00:46:41saratogahard to believe the SDL buffer sizes are hard coded
00:46:41JdGordonBlue_Dude: it is definitly worth doing, even if SDL needs special casing
00:47:21Blue_DudeI don't think it's hard coded. It's just that the lib function has a lot of latitude to decide what's best given the hardware.
00:47:49Blue_DudeJdGordon: I think this is beyond special casing. I'm not sure it'll work at all on the sim.

00:57:06ChernAlexP: that is a rather bad mix
00:57:19AlexPIt seems to work quite well usually
00:57:38AlexPAnd it doesn't separate the devs from users which we don't want
00:57:46saratogai've wanted different channels for a while since it makes skimming the logs a lot easier, but most people don't
00:57:56Chernaah, I guess that is alright for small developments
00:57:57n00b81I don't see why not.
00:58:13AlexPOne argument is that you end up having to read both anyway

00:59:00Chernso do you work for your own enjoyment? or do you slave for the users?
00:59:01scorchesupport topics often turn into development topics, so it makes going through logs harder as you would likely have to go back and forth
00:59:46AlexPChern: Hard to speak for everyone, but principally for ourselves
00:59:58Blue_Dudedevs are slaves to their own improvement requests.
01:00:00AlexPChern: Of course we do care about users, but not as the be all and end all
01:00:17AlexPi.e. if users want something the devs don't, then the devs win :)
01:00:51AlexPAnd it depends on the person of course :)
01:01:22ChernBlue_Dude: you hold a strong opinion
01:02:05Blue_DudeMerely ironic commentary. Don't consider it too deeply.
01:02:49ChernI was thinking of porting rockbox to the Playstation Portable, has anyone attempted to do such a thing
01:02:58AlexPNope :)
01:03:12AlexPIt wouldn't make much sense as is IMO, you would want it as an app
01:03:22Chernwell rockbox isn't an app, is it?
01:03:33AlexPIt is a complete firmware/OS
01:03:42Blue_DudeRockbox is an operating system.
01:03:48Chernthats an OS
01:04:10AlexPYeah, so using it as an OS wouldn't make much sense on the PSP IMO
01:04:12saratogais there any reason to run rockbox as an app on the PSP though?
01:04:20saratogait seems like a good firmware replacement target
01:04:27AlexPBut e.g. the simulator runs on a PC as an app
01:04:28saratogathats how those hacked media players on the gameboy work
01:04:40AlexPsaratoga: Oh, as a dual boot?
01:04:42saratogause the built in software as a bootloader basically
01:04:53AlexPI'm displaying my PSP ignorance here
01:05:06saratogawell that the DS not the PSP, but hardware wise they're not entirely different
01:05:14Chernyes they are
01:05:17AlexPI thought of it more as a platform, but I guess that isn't quite true
01:05:25saratogaunless you really want networking while you're playing music i'm not sure what the app option gets you
01:05:48saratogaactually i've always wanted to do a nintendo DS port of rockbox, but never really had the time
01:06:15Chernwell, I was hoping someone would have done it already
01:06:37Chernreplaced the onboard firmware os thingy to the rockbox
01:06:49Chernfaster loading times and more features
01:07:42saratogathese guys have a tool chain and drivers for the PSP
01:07:57n00b81That's not complete at all

01:12:35AlexPDepends on the language
01:12:42AlexPIt is often translated
01:12:52AlexPBut yes, I would expect most people to know it

01:14:17Chernyes, shouldn't probably do that

01:16:55Chernthe hardest part would be breaking the chain of trust in the system
01:17:22saratogai think thats already done
01:17:32saratogaas evidenced by the linux port
01:17:38Chernfrom boot
01:17:57n00b81The linux port is an app.
01:18:08Chernthere is the existing flaw in which they initialize a checksum with a value of 0 in the IPL page

01:23:04Chernanything more specific?
01:23:10saratoganothing else comes to mind

01:35:42ollebeturns out i was wrong about the storage in E10
01:35:59ollebeif anyone is interested, the SoC has 8 Mbit of NOR flash
01:36:16saratogathats just ROM, it won't really matter for rockbox
01:36:41ollebehow can you be so sure?
01:37:04saratogawhat use would we have for memory we probably can't write to and is too small to store anything we would want to write?
01:37:49saratogamaybe someday you would want to write your own bootloader to it to replace the OF one if theirs have some flaw, but most targets don't even bother doing that
01:37:58ollebei'm trying to figure out the original firmware, and I think an additional 8mbit of flash is relevant
01:38:28ollebethe firmware has to be stored somewhere, and this is one place where a part of the firmware might reside
01:38:46saratogaits probably just their bootloader
01:38:58saratoga1MB is too small for firmware on typical players
01:40:21linuxstbsaratoga: Lots of targets have the full firmware in NOR, so it can be important - we need to insert our bootloader there (e.g. the h1x0, h3x0).
01:42:20saratogai didn't say none did it, just that most don't
01:42:51*ollebe goes back to the disassembler
01:44:10saratogahow does installing work on the hx00?
01:44:45linuxstbOur bootloader is merged with an OF upgrade file, and then the OF is used to flash it to NOR.
01:45:05saratogaah so like the sansas
01:45:24*Blue_Dude beats head against SDL code. Cries.
01:45:32tmzt_kugel: alsa won't, but you can maybe use alsalib with win32 pcm output, though I don't know why
01:45:38linuxstbsaratoga: Which ones?
01:45:55saratogaAMS at least, PP too I think
01:46:12saratogaalthough its technically a NAND flash chip it goes on

01:46:24saratogasince NOR isn't so popular anymore
01:48:01 Nick fxb is now known as fxb__ (
01:48:59linuxstbYes, similar to AMS. PP is different - both the bootloader and OF are stored on the NAND, and sansapatcher replaces the OF completely with our bootloader, and moves the OF image somewhere else in the firmware partition so we can dual-boot.
01:51:08saratogaoh ok

01:52:32Blue_DudeOh FFS. is SDL just hosed in Cygwin or does anybody else have this problem?!
01:53:12Blue_DudeYou'd think the SDL.dll would work the same as the lib, right?
01:53:58saratogaRandomInsano: just because it links doesn't mean any of the addresses are correct
01:54:19saratogaare you sure you've actually put your code into system RAM where the system will execute it?
02:01:03Blue_DudeOK, I'm done. Anyone know how to get hold of the SDL guys? I'm totally stuck.

02:04:39RandomInsanoI don't actually know how rockbox does anything really.
02:04:39saratogayou should probably compare to the OF and check then
02:05:08RandomInsanoI can barely read assembler. It's inital jump is in the 0x20000000 address space.

02:06:33saratogaeither could be wrong
02:06:58saratogaalternatively, you could try patching the OF with your code to verify that the GPIO pins work the way you think they do
02:07:03RandomInsanoThen here's the fun problem: how do I find out?
02:07:38RandomInsanoHow can I patch the original firmware? Plunk some compiled assembler then change the original telechips jump call?
02:07:58linuxstbRandomInsano: The telechips bootloaders can be built in two ways - either to run as standalone, or to be appended to the OF. I'm not sure what the default is for the iaudio 7...
02:08:05RandomInsanoThat'll be fun to figure out... Any docs to guide me?
02:08:35RandomInsanolinuxstb: What's the default on your telechips port
02:09:02linuxstbThe source is the documentation... I'm just looking now.
02:09:10RandomInsanoAnd how can I find out the differences? There isn't a lot of documentation on how everything bulds and compiles
02:09:37Blue_DudeSigh. SDL isn't ever going to work the same way as the target hardware. SDL is double buffered and requires the buffer to be full before the callback ends. Since my design requires the hardware to actually DMA, I think we're stuck.

07:38:12saratogaFWIW i've only got ARMv5 targets handy
07:38:22saratogai think the multiplier does too
07:38:46saratogaat very least since its 2 cycles latency on a multiply, theres probably an extra stall if you try to use it immediately

07:40:54saratogawhats a late register?
07:42:29jhMikeSthere's the early registers, which are needed upon issuing the instruction, and the late registers, usually result registers that are only updated in later stages, so they're not interlocked until a result is written. each is explained in the spec.
07:43:47jhMikeSto clarify, it's specified on a per-instruction or operand type basis
07:44:08saratogaah ok so basically the late registers are just things that only need to be ready by the end of the op, and not the beginning?

08:08:01saratogais there any advantage to trying to issue mul right after a ldm command? i'm wondering if the multiplier can be working at the same time as long as they don't share any registers

08:33:03saratogaits more then 10 MHz IIRC
08:33:43saratogai though they claimed like 20MHz, and only by significantly sacrificing accuracy
08:33:57*jhMikeS remembers seeing *something*
08:34:06jhMikeSwhat's PP claim?">
08:37:14saratogathis says 18MHz on ARM9E
08:37:38saratogathough since its arm ltd, i'm guessing they're using their emulator and assuming 0 latency memory
08:37:49saratogarather then an actual hardware implementation with DRAM
08:38:37saratogai guess turning the S clock way down would improve the total mhz since then teh DRAM would look a lot faster
08:39:35saratogaalso I like how almost that entire PDF talks about parts of the decoder that use negligible time
08:40:19saratogahaha and they brag about figuring out how to do a fourier transform in nlog n time
08:40:21saratogagreat work guys
08:40:26jhMikeSagreed, it seems perhaps it's 70-80% faster at 528 than 264.
08:41:00saratogaCarl Friedrich Gauss wants to high 5 you, but he can't since he figured that out 200 years ago and is now dead
08:42:10saratoga"The target architecture is capable of implementing a memory load in 3 cycles and store in 2 cycles. However, by organising the data so that memory access is via consecutive addresses it is possible to achieve effective load and store operations in a single-cycle, which significantly enhances the performance of the convolution operation."
08:42:16saratogawe don't do that
08:42:20saratogaactually we thought that wasn't possible
08:43:04jhMikeSyes, keep dependencies spread apart in the stream I always say
08:44:36saratogalooking at the imdct we also don't exploit the imdct_half trick from ffmpeg, though thats probably not going to make much difference
08:45:08jhMikeSwhat's that?
08:45:38saratogabasically, the output of the imdct has middle half symmetry, so you really only need to produce half as many samples
08:45:49saratogayou can generate the rest when windowing
08:46:08saratogabut the symmetry is kind of ackward, so in reality it doesn't save you much, at least not on arm
08:46:36saratogastripwax worked it out a while ago, i think you could save maybe 1 load per PCM sample produced
08:47:07saratogaand of course you saved memory, but since the mdct is only 36 samples for mp3, thats only 18 bytes saved!
08:47:22saratogaerr 18*4
08:47:34n1ssaratoga: loading and storing multiple registers at once is a nice improvement on coldfire too (when using asm, gcc seems to never use movem by itself except for storing and loading register on the stack)

08:48:56saratogalookinag at synth_full.S, i bet reordering the imdct output wouldn't help much on arm9 since most of the ldr time is probably hidden by stalls in the multiplier anyway

13:14:02lovelesslinuxstb: it's the fallback when flashing a faulty firmware lets you only get into manufacturing mode
13:15:50linuxstbloveless: Yes, but I don't think you need i2c now do you? i.e. for early development you can just use e200tool to upload and run your own code. i.e. replace "arm_code.c" with your own code.
13:15:54n1sah that's very useful
13:16:01pixelmalast logged in here over 5 months ago (doesn't mean he said something)
13:16:30lovelessn1s: from what i can tell its not a mode as such. there is a button combination to put the view into the mode where it accepts download of a rom image, but the current pp5020-specific code of the e200tool fails very early in the init at processor detection. the i2c code implemented there should be largely compatible except for the base address, perhaps.
13:17:41 Quit mirak (Quit: Ex-Chat)
13:18:26lovelesslinuxstb: i am not sure i understand. i will have to look into the e200tool again to see how far it can currently access the view.
13:19:20 Join Casainho [0] (
13:19:38lovelesslinuxstb: the way i see it, flashing in manufacturing mode is implemented via i2c running in a minimal rom stub that is transferred via usb.
13:19:48 Join CGL [0] (~CGL@
13:19:58linuxstbloveless: The way e200tool works is that it firstly uploads an ARM binary (arm_code.c) using "USB boot mode". This code is specific to the older Sansas, and contains a USB driver that is then used to make a new connection to e200tool, where two-way communication happens.
13:20:08lovelesslinuxstb: but please correct me if i am wrong there
13:20:28linuxstbSo for testing your code, you simply need to use usb boot mode to upload your code. e200rpatcher does the same thing.
13:20:51linuxstbi.e. you can ignore most of the functionality of e200tool.
13:21:45 Join robin0800 [0] (
13:22:25lovelesslinuxstb: so probably the USB code currently fails on view

13:23:52linuxstbi.e. at this stage, you want a safe way to run your code on your view. "USB boot mode" (aka manufacturing mode) is simply a way to load a binary into RAM via USB, and that's a feature of your Sansa's boot ROM. This code isn't flashed.
13:24:05lovelesslinuxstb: interesting. i am not too familiar with these processes. it's exactly why I am looking for some tutoring here. :)
13:24:57linuxstbIf I was you, I would ignore e200tool, and look at e200rpatcher.
13:25:24lovelessI am aware of the untouched boot rom, but from there my knowledge about the bootup goes fuzzy

13:27:48lovelesslinuxstb: so your approch would be to come up with some testing code, push it via manufacturing mode, and see if, say, the led blinks etc.
13:27:51linuxstbe200rpatcher basically just uploads a binary in USB boot mode which is then executed. Currently, you need to compile e200rpatcher with that binary embedded into it, but you could modify it to read it from a file. That binary will be your test code.
13:28:00linuxstbloveless: Yes, exactly.
13:29:22linuxstbThe code e200rpatcher uploads is in bootloader/main-e200r-installer.c You compile it by selecting an "I"nstaller build for the e200r.
13:31:32lovelesslinuxstb: okay. i might still stick to my plan of getting i2c in the e200tool working just for getting some practise. ;) you could call me an ARM noob, I guess. although i read a great deal about the platform in general, but i lacked most of the pp specifics. got some idea about the memory layout.
13:32:21linuxstbloveless: I don't think I would do that - if you damage the boot rom, you've likely bricked your sansa...
13:33:38lovelessno, i don't intend to touch the bootloader. just the usb/i2c code that is uploaded into ram via usb.
13:35:23lovelessor am I missing something here?
13:35:34linuxstbOK, but in my opinion your time would be better spent on other things - you don't need that code at all...
13:36:19lovelessI am just looking at the e200rpatcher now. will need some time to feel at home there
13:37:54linuxstbloveless: The main function is do_patching() - which uploads the binary to your Sansa in manufacturing / USB boot mode. The binary e200rpatcher uploads is designed to modify (patch) a hidden part of the NAND disk, hence the name.

15:08:50linuxstbloveless: The first thing I would do is to upload some code that has a small delay loop and then reboots the device. You can vary that delay loop to give different feedback. This would confirm your code is running. After that, you can try other, more useful things.

16:39:54amiconnkugel: Our creat() and open() used to have flags, but that was removed
16:41:57amiconnIt makes no sense to keep a parameter that does absolutely nothing in rockbox. It only costs binsize
16:42:14kugelwell, wasn't it flags actually? I saw in the logs that people used to call it with O_WRONLY
16:43:06amiconnFlags do exist
16:43:39kugelnot for creat()
16:43:43amiconncreat(9 has no flags in posix either, 'cause it wouldn't make sense
16:49:48kugelnot having mode decreases portability. but that wasn't much of an issue until now
16:50:54amiconnYes, but having it costs binsize for no gain
16:51:25amiconnYou could #define things for portability. It's not that you could port a posix app to rockbox without changes anyway...
16:51:59kugelI don't want to port a posix app to rockbox, but rockbox to a posix system ;)
16:52:56Bagderit'd be easy to have the rockbox version be #define open(x,y,z) rockbox_open(x,y)
16:53:36kugelyes, unfortunately it's the other way around
16:53:54Bagderthat's easy too, as then you'll just have a wrapper function

16:56:11kugelso you're saying I should rather add 0666 to every creat() call, and do a #define open(a,b,c) rockbox_open(a,b) instead of replacing all creat() calls with file_create()?
16:56:47 Quit mirak (Remote host closed the connection)
16:57:35BagderI haven't given it enough thought to say which way I prefer really...
16:58:23kugelI have done the second, but I don't feel strong about it. I'd rather keep some sort of posix compliance though
17:03:52kugelhm, the more I think about it the more I prefer the s/creat(file)/creat(file, 0666)/ way
17:04:27kugel(though I'd use 0664 instead)
17:05:21gevaertskugel: no reason. This is still passed through umask
17:05:32 Join mirak [0] (
17:06:36kugelI think 0664 is more appropriate, why depend on some extra mechanism to make it to 0664 for us?
17:06:55Bagderextra? that's just how it works!
17:07:11gevaertsbecause (a) we don't know what the user wants, and (b) the extra mechanism is always there
17:07:34Bagderthe whole point of umask is to allow the user to decide the rights
17:08:44Torneindeed, umask is not optional. 0664 is wrong on some systems as well :)
17:08:50linuxstbkugel: There aren't that many calls to creat() in the core anyway - most are in plugins. So the binsize impact shouldn't be much. But if we use a mode for creat(), shouldn't we also be doing it with any calls to open that create a file - there are quite a few of those...
17:10:19FlynDicefunman: (logs) I've taken your PIO patch and modified it to use the same transfer mechanics that the linux patch uses for PIO. I adjusted most units to bytes vs words except a conversion to words happens just befor the actual transfer.

17:12:09FlynDicefunman: I get a DTO but there are still bytes left. With rx watermark at 20 there are 84 left but if I change to 80 only 24.
17:12:16amiconnlinuxstb: When umode was removed, it saved quite some binsize
17:12:43amiconnEven if the function just ignores the argument, each call has to pass it
17:12:44kugelthe mode would be removed through #defines

18:09:33saratogaanyone object to putting up an official fuzev2 bootloader now?
18:09:35linuxstbsys/types.h is something different.
18:09:38saratogawe have one for the clipv2
18:10:23kugelmy sys/types.h defines (u)intN_t, and is included by stdint.h
18:10:30linuxstbsaratoga: If it works (i.e. safely dual-boots), then go for it. Don't forget to build it with a real versoin number and tag in svn though.

18:11:12linuxstbYes, but what is your system?

18:11:30kugelubuntu 10.04
18:12:21linuxstbSo just to be clear, in Ubuntu, sys/types.h includes inttypes.h, and inttypes.h includes stdint.h ?
18:13:03kugelinttypes.h includes stdint.h, which includes sys/types.h

18:13:56linuxstbsaratoga: Perfect - I think that's exactly what others use.
18:14:08kugelI don't see why we need released bootloaders for unusable targets, but well..
18:14:34kugelthe clipv2 once was unstable which is why it has one
18:15:00saratogaso that people don't use random bootloaders they find on the internet
18:15:20kugelrandom as in the ones funman regularly posts on abi?
18:15:36saratogadid he post a bootloader?
18:15:40kugelpeople shouldn't be using rockbox on the fuzev2 at all, so I don't care what bootloders they use
18:15:59linuxstbkugel: OK, but on my Debian unstable system, stdint.h doesn't include sys/types.h. So I don't think you can assume that everywhere. C99 _does_ specify that inttypes.h includes stdint.h though.
18:16:04kugelreleasing a bootloader somehow implies for me that we're doing support for it
18:16:44kugelso it was technically correct to replace sys/types.h with inttypes.h, wasn't it?
18:16:57linuxstbkugel: No - that's what I'm trying to say.
18:17:14linuxstbWell, it depends _why_ that file was using sys/types.h

20:11:13lovelesslinuxstb: yes, that's what I did.
20:11:30lovelesslinuxstb: main-e200r-installer.c compiles just fine if I use system_reboot() that comes in via system-pp502x.c and it's respective includes and dependencies. but when I spell out the inner workings of system_reboot() directly in main-e200r-installer.c, the compiler bails out at assembling the cpsid mnemonic.

20:13:24lovelesslinuxstb: it should be this one, but I'll check.
20:14:19linuxstbloveless: Yes, system-pp502x.c should be right. So it's the disable_interrupt() function that's causing the problem? If so, then just comment it out, as interrupts shouldn't be enabled anyway (I think).

21:24:18kugellinuxstb: i have a patch fo creat(), what should I do about open()? you said there are some files which use open to create files?
21:26:23linuxstbkugel: Yes, just grep for O_CREAT. I guess those could be changed to use creat if they are using the equivalent flags to creat()
21:26:50linuxstbBut I wouldn't say it's important. Personally, I prefer open(), as it's more explicit...
21:27:40*kugel wonders how horriby outdated firmware/test is
21:27:57linuxstbThat's the FAT driver testing code?
21:28:55kugelnot the slightest idea ;)
21:32:03kugelmaking open() posix compliant would probably have an impact
21:32:34kugelI think you can't inline variadic functions, as they mean passing parameters on the stack

21:38:13linuxstbkugel: Hmm, as the mode is only needed when O_CREAT is used, perhaps we should be using creat. Then (IIUC) we can stick with our two-parameter calls to open() everywhere else.

21:41:22linuxstbkugel: I see the answer to that is "yes"... So no, that won't work.
21:42:16kugelwe can still ignore the mode in rockbox easily, but just changing it to be variadic has an impact
21:42:32kugel(an impact I don't really care about, but I guess amiconn does?)
