The board appears (or not ?) supported, among installation files on
NetBSD site i can see several ARM kernels, including "CUBOX" and
"CUBOX-I" variants, so i assume that the support is in place.

I've downloaded the official armv7 installation image (checksum OK) in
an x86_64 NetBSD VM running on my main workstation, then installed
SolidRun U-Boot official version (with other versions -> black screen
only) using loop device method:

Host-001# ls
armv7.img              spl-imx6-sdhc.bin      u-boot-imx6-sdhc.img
Host-001# vnconfig /dev/vnd0 armv7.img
Host-001# dd if=spl-imx6-sdhc.bin of=/dev/rvnd0 bs=1k seek=1 conv=sync

Host-001# vnconfig -u /dev/vnd0

Then flashed the resulting image on SD Card via BalenaEtcher, also
trying several of them just in order to avoid a bad one, without

Here the boot log, captured via Cubox serial console:

Pretty sure this is the problem

Check what dtb it's looking for via u-boot 'printenv'

No other messages at all, board hangs until spontaneous reboot.




options 	EARLYCONS=imx, CONSADDR=0x02020000
(hopefully this is right for your imx6)

will help as well.
