Re: Help amdgpu kernel 6.4 sifive unmatched

Hi Bo,

Thanks for your feedback! I forgot to mention the model of my video card 😅

It is a Radeon RX 570. The system output is:

´´´

I also for experiment removed xserver-xorg-video-radeon and xserver-xorg-video-ati in order to only have xserver-xorg-video-amdgpu installed. And removed all kernel flags but

´´´

root@unmatched:/# cat /proc/cmdline
root=/dev/nvme0n1p4 rw quiet console=ttySIF0,115200 net.ifnames=0

Thanks! I'll continue trying options 👍

Regards,

Edson

What is your graphics card? my is AMDnRadeon HD 5000/6000/7350/8350
Series, so one firmware-amd-graphics maybe can work here.

yeah, I have such dmesg after rebooting every time. But once it passed
the complaint, the whole system worked normal.
The log maybe from power issue with the graphics card.

In fact, the wiki you followed I think was some obscure. I am not sure
your u-boot-* file was put where. But
I remembered if putting them on SD and nvme separately and this caused
maintainance trouble: after upgrading kernel
need to copy from SD to nvme. So I just simple here: on nvme, there is
only rootfs; on sd card, there is only
u-boot-* file. it works! But if you enable to boot from onboard SPI
Flash as the wiki, you do not need sd at all maybe.

Here is my pre-built Unmatched Debian image(hope this helps):
https://github.com/yuzibo/Unmatched-Debian-image/releases/tag/0.0.2

Then dd these images into nvme and sd separately then the system
should work. On my system, there is no kernel parameters,
just:

rv@debci-01:~$ cat /proc/cmdline
root=/dev/nvme0n1p1 ro quiet
