Hi, everyone!
AFAIK openSUSE does not support Raspberry Pi 4 Model B yet. [1]
I’ve bought that board, I know the very basics on how to use it [2] and I want to help to port openSUSE to it. How can I start?
I'm working on some (still hacky) support for RPi4. You can find the JeOS image in my home project [1]. Beware that I was able to break the build of U-Boot yesterday. I'll try to fix this tonight.
I just gave that image a try and after a while staring at a console with no activity I noticed that it's the JeOS with jeos-firstboot, so I had to remove "console=tty" to actually see anything. Using the HDMI console won't really work without USB support.
Why? HDMI output should work.
Also, chrony-wait should be disabled, it delays booting by 10min as no network is currently working.
Yes, networking is on my list.
What doesn't work: - USB (expected), but the OTG port seems to be available. It's forced to host mode by the kernel though as gadget support is not enabled - WiFi: brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000): clkctl 0x50 I see that you force-disabled WiFi stuff in JeOS.kiwi, I had to copy over the firmware manually
Does it work reliably? I heard that it has some hick-ups.
- Ethernet: Gets detected just fine, but when actually sending packets the kernel freezes (sometimes with NETDEV WATCHDOG: eth0 (bcmgenet): transmit queue 1 timed out) - Sometimes the UART (clock?) glitches and there's garbled text
Really? Did you change anything in the config.txt? I haven't experienced this up to now.
What does work: - u-boot, grub, kernel, sd card, serial - I/O activity LED :D - cpufreq: Speed of "bc" corresponds roughly to CPU frequency
So very nice progress already!
Thanks :)
I'll try to build a kernel with dwc2 peripheral support, maybe that's enough. Probably not though, considering it's USB-C...
That's not enough. Nicolas is working on some patches to enable PCI, which is needed by USB.
Thinking twice I suspect that this was not correct.

Cheers, Fabian
