untested

hw video encode/decode (most probably not working)
external display (might work)

problems

gpu requires self built newer version of the xorg server and most proably older mesa version due to regressions in newer mesa versions

Thank you this appears to be functioning properly on an HP Chromebook 14 G3 (nyan-blaze).

Hey! Thanks for the great work. I'm writing to report that, on nyan blaze (2GB RAM),

HDMI works
Audio is not working (I'd like to make it work, but I can use some pointers)
WiFi is intermittent (I think it worked fine before running sudo apt dist-upgrade)

wifi_not_working.txt wifi_working.txt Here are some dmesg logs with wifi working and not working. In ChromeOS, it always work.

hexdump0815 commented 3 weeks ago

i'm surprised a bit - i have a 2gb nyan here as well and audio is working (one needs to switch the output by hand properly iirc) and also wifi is working - maybe the updates overwrite the wifi firmware at some point - just try to put those files back in place and see if that helps: https://github.com/hexdump0815/imagebuilder/tree/main/systems/chromebook_nyan/extra-files/lib/firmware/mrvl

good luck and best wishes - hexdump

How do I install this?

eutampieri commented 3 weeks ago

@legendaryfishwastaken what are you referring to? If you follow the guides on the repos, you'll download a rootfs image to extract to an SD card.

Is it normal that I have so many files?

hexdump0815 commented 3 weeks ago

@eutampieri - that might be right, but only the ones copied in from the extra-files area will be used on the nyan ... after copying them in it might be a good idea to "apt-mark hold firmware-libertas" to avoid the firmware files getting overwritten again (maybe the copied over firmware files were only required for the legacy kernel initially used - i do not remember anymore completely) ... but looking at this package it seems the firmware files installed have a different name, so no risk for the added files to get overwritten ... so lets forget about all that - it seems to not be the problem on your system - which kernel version is this?

i looked at your dmesg output and "mmc2: error -110 whilst initialising SDIO card mmc2: error -110 whilst initialising SDIO card" does not look good - what do you get with "dmesg | grep -i firmware"? ... maybe it is not even firmware loading related as the above error comes (accoring to the time stamps) before the firmware loading happens in your working dmesg output ... can you please put at full non working wifi dmesg up somewhere?

update: ok the extra copied firmware files were only required for the legacy kernel - https://github.com/hexdump0815/imagebuilder/commit/ce014e0f7f18fb1a90ca63f5555c7ccda72948eb - as such they should not be relevant for your problem
