Hi, i have an issue with booting from sd card. I'm using Debian Stretch 9.3.0 (firmware-9.3.0-amd64-netinst). System CAN boot but issue is in cold booting (when you remove power). It will say "please insert boot device" if i press "ctr+alt+del" udoo boots normally. If i do warm reboot or shutdown and start system boots. I have reproduce this on multiple udoo. All running BIOS 103.
Looks the same as this issue: https://www.udoo.org/forum/threads/boot-on-sd-card-works-only-after-ctrl-alt-suppr.8100/
