I finally have had some time to try to get opensuse Tumbleweed to boot on my 2Gb rock64. The image I used was downloaded from: https://download.opensuse.org/repositories/devel:/ARM:/Factory:/Contrib:/ Rockchip/images/ After dd'ing the image to the emmc, I installed the Arch u-boot using this install guide: https://archlinuxarm.org/platforms/armv8/rockchip/rock64 Using these kernel arguments in grub2/grub.cfg . I'm able to see where the boot process stops: $linux ($root)//Image-4.19.5-1-default ${extra_cmdline} loglevel=7 earlycon=uart8250,mmio32,0xff130000 console=ttyS0,1500000n8 splash=silent plymouth.enable=0 root=UUID=d90c3637-cea7-412c-8aa7-e3a5a47dad39 rw So after unpacking the initramfs, it stops after saying it can't open the rtc.
