Hi Nicolas,

thank you Fabio for adding me, I’m going to give a
try soon with imxrt1020-evk board and check, as well as with imxrt1050-evk.

It passed some time since I’ve added them to
uboot and maybe something is broken now.

Also, if you then have further question ask me.
Do you mean to run some OS after uboot?

Linux is still there waiting for someone interested on it, as well as uboot support for other peripherals.

PS: sorry for too posting but I’m on mobile.

Best regards
