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.
