15:36:44pamaurylebellium: I just noticed something very odd
15:36:57pamaurythe usb cable of my A15 doesn't work with old devices like E580 or E460
15:37:16pamauryactually if you look at the pins, you can see that it has one pin that is not populated compared to older cables
15:40:38lebelliumboth cables in front of me have 9 pins populated
15:40:44lebelliumbut I don"t remember where they come from
15:41:06pamaurythis one only has 8 populated!
15:41:17lebelliummaybe the A15 cable is still in the original box
15:41:19lebelliumI check
15:41:47pamauryinteresing, so if I use Sony's test_backlight binary to switch off backlight and use aplay to play music, it doesn't stuter when backlight is off
15:42:27lebelliumaha yes the cable is still brand-new unused in the A15 box. And yes there is one pin missing
15:49:20***Saving seen data "./dancer.seen"
15:52:57pamauryit's annoying, a bought some cheaper VMPort to jack and AC VM port charger in hope to get a VM port with all pins but no
15:53:17pamauryI want one to experiment with the UART but Sony seems to make a point of having unpopulated pins
15:53:25pamauryI think I need to rip off a dock
15:53:32pamaurybut those are expensive and rare
15:56:11pamaurylebellium: do you have any Sony dock you don't want anymore? ;)

18:46:40CH23johnb2: are you trying to flash a disk image to the clip+? i had a read only clip+ as well, but i could copy within rockbox from my µSD card to the internal memory still, and installed multibootloader that way.
18:47:26johnb2I tried copying from sd before, but the file never persisted.
18:48:21BilgusI wwon't be back for a few hours but i'll check in when I get a chance
18:49:12Bilgusjust make sure you read back after each try and make sure what you read back either matches the backup you made at start or the new image

18:49:51Bilgusyou just don't want to leave it in a corrupted state
18:57:52BilgusIf we are going to make a real recovery firmware we should probably set up a way to do it from within rockbox like make it not pop up the usb screen and lock it to a debug menu
18:58:48Bilgusright now I just lock the buttons so no one gets confused I really don't want them accidentally formatting that drive if they plug it into a windows pc
18:59:21Bilgusso maybe it should have a message
18:59:28Bilgusand a prompt
19:01:18Bilguseven better would be to figure out how to do a NAND test and bad blocks marking from within the firmware but I fear thats above my abilities

21:16:59wodzpamaury: the lack of qemu documentation AND various device models at various stage of transition between the oldest/older/super fancy new APIs makes it really a pain

21:17:56wodznot speaking about weird custom OO model crafted in plain C + macro magic
21:18:40pamauryyeah last time I looked it was horrible
21:18:58pamaurythere are so many different APIS and nothing is documented
21:20:57wodzI'd say the worst thing is that codebase is mix of various APIs and styles doing basically the same at the end.
21:21:26wodzso a bit similar to rockbox codebase :-)
21:22:07pamauryyeah, in some sense it's worse than rockbox though, because of the never finished transition to the new device model, it's not clear how you should write drivers
21:38:42pamaurythis audio problem on the nwz is really weird
21:39:11pamauryas far as I can tell, no underflow is happening, yet audio still stops for like .25s randomly when baklight is off

21:44:10pamauryI've done a hacky test and if I disable our pcm-alsa code and call aplay to play a file, it seems fine
21:44:27pamauryso I suspect this is related to ALSA, maybe it's an ALSA bug, or some bug in Sony's implementation
21:44:46pamauryI just don't underatand why it's related to backlight

21:49:27***Saving seen data "./dancer.seen"
21:55:58pamaurythe weirdest thing is: if I use pcm-alsa async mode I get this behavior, and if I use the old pcm alsa tick code, it essentially dies the moment backlight turns out and never recovers
22:00:34wodzwhich mode sony's aplay is using?
22:01:27pamauryit doesn't use async mode as far as I can tell
22:01:46pamaurybut it's implementation is hell-safe, it will recovery from virtually any error you can throw at it

22:05:59lebelliumwhat are the additionnal pins for?
22:07:32pamaurythey could have an accessory mode that controls the player I think, like apple accessory mode
