Hello Hilbert,
I looked into the Coreboot logs (SeaBIOS ones, you have posted recently).
My comments with: <<=================================== _______
ress ESC for boot menu.

I have no idea if yuo have there attached HDD/SSD drive? If you do, with GRUB2 + Linux (whatever Linux distro it is), it depends how the drive is configured?
Either for UEFI (will NOT work), either for UEFI + MBR or MBR only - should work. You need to investigate what yuor attached drive is: cat, dog, or combination (UEFI, MBR, or MBR + UEFI)?
Please, upgrade me with the info I requested (memory and drive)?
Thank you, Zoran _______

Hi David,
After trying to use SeaBIOS as payload, I got more information about reboot issue as attached file. While U-Boot just reboots directly and Grub hangs, the SeaBIOS’s dump complains “No bootable device” at the end. Do you think is it the cause of reboot? Can I say my U-Boot and Grub versions are not supporting BDX-DE?
