AFAIK openSUSE does not support Raspberry Pi 4 Model B yet. 
I’ve bought that board, I know the very basics on how to use it

I'm working on some (still hacky) support for RPi4.
You can find the JeOS image in my home project .
Beware that I was able to break the build of U-Boot yesterday. I'll try to fix
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
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
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
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!
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.
