Hello,

I wrote in the past "notes / process tasks" to follow for fresh install
OpenBSD on a RockPro 64, was done for 6.7-current.
I don't know if still available:

https://blog.burelli.fr/en/arm/arm64-install-openbsd-rockpro64/

For now i am using quartz-a-model from Pine64.


Succently:

* dtb has to be installed on the USB Key, because kernel on usb key has
to detect the emmc and has to be able to write on it. Without
installing dtb on the USB key, it's impossible to write to the emmc
card.

--> After reboot the installed kernel should detect and write on the
emmc. install dtb if not.

Ations to do on another machine to prepare the installation (sd1 is usb
key):
doas mount /dev/sd1i /mnt
doas mkdir /mnt/rockchip
doas cp /usr/local/share/dtb/arm64/rockchip/rk3399-rockpro64.dtb
/mnt/rockchip/
doas umount /mnt
