I would like to change out the OS by gentoo, to have it similar to my other 6 K8s nodes.
I have already build an image which is running, with the rockchip-bsp repo and informations.
But console output is stops after “kernel starting”, and the tty file is not present on the linaro Filesystem when booted.
Which configuration do I have to change to get console output after u-Boot going.
I connected a screen to the HDMI output, but screen stays black.
These cm3s are running on a turing pi 2 whith raspberrypi-cm4 adapter cards. But I do have a radxa cm3-io board here also.
That also means that, if the system is not working after changes, I have to reflash with radxa-cm3-io Board with an sdcard, and than flash again from the sdcard to emmc. Makes it costly to go by trial and error.
