I just tried the latest Leap 15.3 image, openSUSE-Leap-15.3-ARM-JeOS-chromebook.armv7l-2021.05.31-Build8.7.raw.xz The system boots (just press ctrl-u on start-up to boot from SD card), but neither u-boot, nor kernel do show anything on the screen, which stays black, despite the backlight being enabled. I can login blindly with root/linux and execute some commands. I will try to debug further later.
