00:00:55slaterthere is no way to manipulate the bootloader, even when the firmware is completely erased the bootloader is still on there
00:01:42saratogathats actually how nearly all rockbox targets work
00:02:00saratogawe generally prefer to leave the bootloader alone even if it can be changed, that way you don't risk bricking your player
00:03:32slaterwell I don't know how I could achieve that on my given system
00:05:00saratogayou said the other day you had code execution
00:05:14saratogaso whats the problem?

00:05:38slateryou mean generate the bootloader binary
00:05:48saratogai mean execute rockbox
00:05:54saratogaload it into ram and then run it
00:06:05slaterthats what i am trying to do at the moment
00:06:21saratogaas an application
00:06:44saratogai'm asking if you have an actual reason to do that verses running it as a firmware
00:07:33mystica555i'd want it as an app on such a target simply to allow better audio playback, and still retain the extra goodies from the firmware it shipped with
00:07:33mystica555why remove whats useful?
00:08:33slaterI honestly don't see the problem. if it runs as an application thats cool, and maybe then i have enough knowledge to port firmware
00:09:03saratogaso basically, you're doing it because you think an application port will be less work?

00:22:05slateri think either way is hard to do. and for me i am still learning on all that stuff since its my first try ever doing it. I am doing this in my freetime as well and spending time so that others could also run rockbox. for me porting as an app is a more logical approach since I do not know every little bit about how to write drivers. i am a still a beginner.
00:22:54saratogaok thats all i was wondering
00:23:02CIA-7New commit by bertrik (r28537): Simplify unsigned int <-> unsigned char array conversion in ipod_remote_tuner.c (make it endianness independent)
00:24:03slateri mean i'd love to see it running as a firmware, but for know my knowledge is to limited on how to do it. I am reading through a lot of stuff and hope to be able to do it someday

00:56:51slateron the player? or on my pc?
00:57:19tmztif you have linux source porting to rockbox is probably pretty easy (compared to not having it of course), what soc is this?
00:57:31tmztno, I meant are you building a kernel
00:57:59slateri could build kernel with zimage
00:58:05slaterlimited to 1MB
00:58:23slaterthe rest of the kernel modules i could place in cramfs but its pretty full aswell
00:59:16tmztoh, rockbox port would certainly be better then
00:59:30tmztrbaaa needs sdl and some other stuff
00:59:34tmzthow much storage do you hve?
00:59:40slatersdl is already compiled and in it
00:59:56tmztokay, what cpu/soc is this
01:00:02tmztwhat is the audio codec
01:00:04slateri am at 15.5mb now i have 16 mb - about 200k
01:00:24slaterimx 37 freescale with vpu and audio codec

01:03:26tmztwhat kind of video support are you going for within rockbox?
01:03:34tmztI don't belive they support more than mpeg1 and maybe 2
01:03:47slaterrockbox i think only mpeg 2
01:04:21slateroh and mpeg 1 your right
01:05:23tmztokay, and framebuffer is it through dsp or direct? I haven't played with imx yet
01:05:51slaterfrom what I guess I am not 100% sure though its framebuffer
01:06:00slaterbut its samsung proprietary
01:06:10slateri can't tell for sure what the driver does
01:06:55slateri mean through dsp

01:13:48slaterits filled up with samsung dsp and other samsung libraries
01:15:56tmztoh, like their tvs

02:49:28Daniel75Sorry for the bombardment of questions
02:50:14soapThat is for the iPod 4G, not the iPod Nano 4G.
02:50:34Daniel75Two questions answered :P, thank you sir
02:51:18soapRockbox's own USB stack is unstable for the Sansa Fuze V2 so Rockbox relies on the Original Firmware's USB for now.
02:52:01soapAs far as Rockbox Utility and detection of the Fize V2, that I can not speak to. Check the forums.
02:52:16Daniel75So I can charge it.... And if I want to revert back to the original Firmware it should still be present on Internal memory?
02:52:56Daniel75Is there anything special I need to do to charge it/connect it to the computer since it relies on teh Original Firmware?
02:53:48soapI _believe_ you can charge from within Rockbox, no need to have the OF boot for that alone. Check the manual. The late-model Sansas are not my strength.
02:53:57 Quit linuxguy3 (Ping timeout: 276 seconds)
02:54:25soapYes, Rockbox dual-boots with the Original Firmware, it is not removed.

10:12:43pixelmawould you rather prefer an \opt that spans 3 lines? And I tried to help readability of the nested ones by using indentation
10:13:53wodzof course its my personal opinion but I really don't like implicit declarations (like \nopt) because it is not obvious what is the scope of such definition
10:15:31wodzwith explicit \opt you can grep the file easily
10:15:56pixelmaI find them more understandable than having tens of *_PAD in one line, you won't easily see if yours is included or not
10:22:25wodzpixelma: well its the same problem as with ifdefing - there are different ways to achieve the same effect and selected syntax is a matter of taste. And as with ifdefing there are corner cases which are not so obvious when reading

19:29:48saratogabertrik: that number is basically a register value for the memory controller, its generally an educated guess given how much memory a player has
19:29:51TheSeventhat appears to work
19:30:47saratogaif it works in ttctool, i would commit it
19:31:38bertrikTheSeven, it plays an audio file?
19:31:51TheSevenit plays raw pcm data at 0x08100000
19:32:03TheSevenglitch-free as far as i can tell
19:32:19TheSeventhe dma things are the interesting part
19:32:33TheSeventhe wmcodec init is just stolen from diagmode
19:33:00bertrikthe intent is to make the playback interrupt smarter, right?
19:33:04TheSevenbtw, that reminds me that i want to figure out the reason for that popping noise when rockbox boots
19:33:27saratogaa lot of players do that, its usually due the anti-click circuit on the DAC not existing or not being enabled
19:33:57TheSevensaratoga: a lot of players do *what*?
19:34:05saratogaclick when the DAC is powered up
19:34:19TheSevenwell, it doesn't do it in the OF, or at least not as badly
19:34:38saratogatheres often a way to shunt that click into a resistor or something similar
19:34:57TheSevenit's probably caused by doing things in the wrong order (there are analog muting circuits between the dac and output amplifier AFAIK)
19:35:13bertrikI think there's also a few players where there's some kind of analog switch outside the DAC

20:08:36Buschelsorry to hear that. hope you're feeling better now?

20:17:20saratogayes I'm feeling better, and will try to find some time to look at the code
20:17:53saratogasince your c code works, I assume its just some silly mistake in the ASM i posted
20:18:14Buschelamiconn: just a performance comparison svn vs. patch on non-PP ARM targets
20:18:17saratogai should probably try translating the c code one line at a time and see where it breaks
20:18:23saratogamy arm is so rusty i might not spot it otherwise
20:18:39amiconnBuschel: Hmm, I could do that now - on Clip+ and Beast
20:18:45Buschelsaratoga: yep. I am curious how much speed up you will see
20:18:53Buschelamiconn: perfect :o)
20:19:36saratogafor devices with fast IRAM (tcc I think) should be close to 2x
20:20:11amiconnBuschel: Any specific bitrates to test? What about layers?
20:22:17*amiconn notices that has neither .mp2 nor .mp1 files
20:22:24Buschelamiconn: no specific bitrate, but layer 3. just a choose a mp3 file with ~200kbps
20:23:36*amiconn should encode the test track with Pegase to .mp1 and .mp2

20:46:39Buschelthe speed up on S5L8701 is about +.25 MHz (~0.5%)
20:46:55Buschelso, I'll drop this patch as well...
20:47:20amiconnWhat's interesting is that our libmad is slower on arm11 than on arm9
20:47:26amiconnIt should be the other way round...
20:47:51Buschelram speed?
20:48:25Buschelit is the same for S5L (arm9) vs. PP (arm7)

21:16:25*TheSeven is still searching for a way to power up that wm8975 without making it pop
21:17:44bertrikso there isn't some GPIO that mutes audio from the DAC externally?
21:18:02TheSeveni don't think theres something outside the codec
21:18:11TheSevenbut there should be something inside actually
21:18:32bertrikif you look at the PCB you might be able to confirm
21:18:38TheSeveneven powering up the internal voltage reference makes it pop, and powering up the virtual ground even more
21:19:02TheSevenwith the output driver powered down!
21:19:06TheSeven(and also the dacs)
21:19:27bertrikI wonder how other targets with the same codec handle this

21:20:46TheSevenit also pops, but not so badly

21:26:58bertrikTheSeven, the WM8971 has some specific info on pop reduction, specifically the order in which to power up

21:28:25TheSeveni couldn't find it while flicking through the datasheel

21:41:15wodzTheSeven: I was fighting high pitch noise when powering up WM8750 in MPIO. I read manual dozen of times, sniffed i2c traffic to codec when OF powers it up and finally I found out by accident that there is GPIO which needs to be LOW on power up.
21:43:35 Join T44 [0] (
21:45:12wodzTheSeven: Manual to the codec doesn't even mention of such possibility. Besides there is paragraph in manual describing steps needed to reduce pop noise on power on.
