how to run it ???

seems like driver bug for me, or card draws too much current and hangs till fw init

maybe it can be fixed like mt7996:

but also possible that semaphore was not released in the code-path…then you need to debug the firmware loading code (e.g. with printks).

Hi
Frank is it available Debian GNU/Linux 12 (bookworm) on R2 ??? or Ubuntu 24.04 .
Is there any instructions on how to build such a system? ( I can try it myself )

frank-w · September 11, 2024, 6:56pm

My images-repo also supports r2…on my gdrive there are prebuilt images (automatic-images folder)

I guess you need to set your clock,e.g.

date -s "2024-09-12 20:51 CEST"

Just change to your own time(zone) and run apt update again

SDXC · September 12, 2024, 7:38pm

Thank you now it works

SDXC · September 15, 2024, 10:34am

what are the main differences Debian GNU/Linux 12 (bookworm) vs ubuntu 24.04 LTS (Noble Numbat,I check both, they have the basic number of packages , e.g. systemd network

frank-w · September 15, 2024, 11:08am

ubuntu is based on debian but is an own distribution…some users prefer ubuntu, some debian
