I managed to get MicroOS running on the weekend :-) TL;DR: Put the custom UEFI firmware from https://github.com/edk2-porting/edk2-rk3588 on a SD-Card and you will be able to boot our TW/MicroOS ISO images. Leap doesn't work. Thanks to the custom EDK2 UEFI firmware from https://github.com/edk2-porting/edk2-rk3588, the board can boot our aarch64 UEFI images. I could install MicroOS from the ISO image on the NVME disk. The board boots and in general behaves and acts just fine. I could not yet get the eMMC to work in MicroOS. It doesn't show up in lsblk nor in the installer but I didn't had the time to look deeper into this. Perhaps the driver is not yet upstream, but I wouldn't know for sure as of now. The UEFI firmware currently runs on a SD-Card and that works fine. I'm not yet planning to flash the internal SPI just yet because it just works and I still want to get some confidence that everything is fun. I also tried to boot Leap Micro 5.5. Grub shows up, but after selecting "Installation" it remains stuck at a cursor. I guess the kernel is too old and the Radxa patches are not yet present there but that's just a guess. In short: Fun little board to play with. I will keep exploring this little fella a bit more but it makes me already pretty happy that Tumbleweed works once you use the custom UEFI firmware.

Hey,

I recently purchased a beautiful Radxa Rock 5B [1] to replace my ageing RPi4 Home server.

Since we have a Tumbleweed image for the Radxa Zero [2], I was having some hopes, that we might also have images for the Rock 5B. Is there something known about it?

Best, phoenix

I with Felix, I have 5B/5A, I love to get tumbleweed on them as well.

A recent U-Boot will serve as well to get the board running, and meanwhile the Leap installer got updated to recognise the SD card. Regarding the supply voltage I can only confirm that a USB power supply with working PD runs fine here after one without PD failed (reboot loops). Beyond that I didn't have to tune anything. The actual voltage is available as VIN6 to the SARADC (Schematics p29, R95132 and R95133 right hs down). The only remaining downside is that the screens stay black, because the DT does not show anything connected to the display engines yet. WiP.

Do you mean the 15.5 installer or the upcoming 15.6 one? Do we already have builds for 15.6?

will just work fine ( serial console only, see above )-:

HTH, Torsten

Thanks, kinda inclined to give it a try. I have a eMMC module attached to my Rock5B which never got recognized, neither on Leap (Micro) nor on MicroOS. It is recognized by the recommended Debian image however. Is there something known about this issue? Also sorry for hijacking the thread :-D
