    So where are we with the Pyra--really?

    I did some work last weekend but didn't really get anywhere so didn't post about it. I no longer get any errors from aplay now, so I guess that's progress :-) but no sound

    The Communication Cube

    The blood and slavery related to the materials used in most mass market phones puts me off getting a new one :p

    Audio Driver (with bounty!)

    Okay, got a bit further debugging this today. Looks like the older drivers used a "platform driver" called "omap-pcm-audio" but this driver was removed and another, generic driver was introduced called "sdma-pcm". This new driver is not really a standalone driver, but more of a way for other...

    Audio Driver (with bounty!)

    Alright, got AESS running on Letux-3.15 kernel now - it was as I expected: too many drivers disabled to cut down on build/boot time. According to htop, playing a 96 kHz audio sample consumes around 1-2% cpu :) same with a 44.1 kHz audio sample. Next step will be to compare this branch to...

    Audio Driver (with bounty!)

    After quite a lot of fiddling I at last got the AESS firmware to build for Linux-3.15 today. Wasn't able to play any audio with my Letux-3.15 kernel, but will have to debug another time. Probably messed up my config trying to slim it down too much :oops: Getting audio working with the...

    Unfortunately no progress. Been too tired during the weekdays and too busy during weekends :(

    Hardware Repair

    According to the datasheet from Digikey, the part numbers mean this: KT11 - this line of switches P2 - hard actuator, 2.36 mm travel SA3M - Right angle with pick & place tab 3 - 3 (?) 5 - gold plated LFG - RoHS compliant and compatible. Gold plated So it looks like it is compatible

    What are you playing this weekend/these days?

    I've been playing Final Fantasy 1 for NES lately, in an emulator on my original Xbox :)

    Audio Driver (with bounty!)

    Looks like that Linux-3.15 repo is simply missing the two commits that adds omap-abe-mmap.c: https://github.com/Risca/linux/commits/omap5_uevm-3.8/sound/soc/omap/omap-abe-mmap.c Notably, the second commit is some kind of big bang "Just fix it" commit before release (my interpretation). However...

    I'll take a look!

    Audio Driver (with bounty!)

    I finally got some time to work on this and I got some news! Before you get too excited: no, I haven't been able to play sound yet :( but I've made some realizations. The old Linux-3.8 driver actually have 2 audio "platform drivers": omap-pcm.c - introduced in 2008 with support for Nokia...

    Everything's a radio if you design it bad enough :-P

    New Kernel for Buster released

    Those look like files used by Letux-OS related to packaging the kernel and userspace configurations. It may be relevant for the Pyra, but has no place among the kernel code (IMO)

    Debug via USB-OTG

    I will :P not much, just a little bit

    Audio Driver (with bounty!)

    Still work in progress, I'm afraid. The DSP is running now, but additional configurations are needed before we can actually use it

    Audio Driver (with bounty!)

    I've sent a patch to the Letux mailing list and notified @hns about the findings. He sounded very excited in his reply :D He was gonna do some testing on his PandaES asap. The PandaES is a similar architecture to the Pyra. I've also pushed the code I used for debugging this issue...

    Audio Driver (with bounty!)

    Finally got some work done on this today, and I might have found the reason the AESS firmware is not running as it should! You see, early during firmware loading we do this: static int aess_load_fw(struct snd_soc_component *component, struct snd_soc_tplg_hdr *hdr) {...

    GOG.com

    Now I understand, thank you. I realize I'm not really the target audience for the client. I install maybe 2-3 games/year and it's mostly story driven single player games you can complete. Don't care much for competition or achievements. I only have a GoG account (shut down my steam account a...
