I updated to my self-build 6.6.135 [1] kernel today. I soft-rebooted, and the issue did not reappear. Hopefully it stays this way. [1] https://github.com/armbian/build/pull/9705

Also interested in this. Was able to install using `sudo ./sunxi-fel -p spiflash-write 0 u-boot-sunxi-with-spl.bin`, where the u-boot image came from the Armbian I downloaded (scp'd it off). That makes use of a patch submitted to the sunxi-tools repo (https://github.com/linux-sunxi/sunxi-tools/pull/232), which does actually work. It is quite happy to boot the image from SD card, and runs even when there is no SD card installed, which is great! However, I don't see any SPI or mtdblock messages in dmesg, and naturally, none exist in /dev/. Am I missing something? Or is SPI not enabled currently for some reason?

Native Steam Client For ARM Linux https://interfacinglinux.com/community/sbcsoftware/native-steam-client-for-arm-linux/

Upstream support for rk3588 is still wip. For desktop usage I suggest to either try "edge" which may have the feature you want already merged in or try "vendor" kernel which is based on Rockchip BSP.

@DaBo Thanks for sharing this. Are you able to run Armbian on this? Is LAN, HDMI, etc working fine on this?
