I'm glad to see your interesting on Radax board.

I have understanded the new scheme. I start to debug it on Radax board yesterday.

Of course, If you want to test, please follow these steps:

First select "Cix Sky1 on Orion O6 (Device Tree) " option on grub UI

Second press "Ctrl+x" to continue boot, and use "root" user to login

Third plug ethernet and execute shell commands:
1) mount /dev/nvme0n1p1 /mnt
2) scp arch/arm64/boot/Image /mnt/Image-pinctrl
3) scp arch/arm64/boot/dts/cix/sky1-orion-o6.dtb /mnt/sky1-orion-o6-pinctrl.dtb
4) umount /mnt
5) reboot

Fourth select "Cix Sky1 on Orion O6 (Device Tree) " option on grub UI and edit it, 

and then replace your dtb and image with sky1-orion-o6-pinctrl.dtb and Image-pinctrl

Please note: add clk_ignore_unused=1 config in grub

Finally press "Ctrl+x" to continue boot, then you can see what expected.

If you have any questions, please ping me any time. Thanks
