UEFI boot hangs with MINNOWBOARD

[Luca Pizzamiglio]

Hi Ed,
thanks for the reply

I tested the last available memstick (r277486) of CURRENT to install
FreeBSD, but it didn't finish the boot process.
The boot process hangs after showing the framebuffer information (
bi_load_efi_data() in bootinfo.c).

I'm using a DVI monitor with a mini-HDMI<->DVI cable.
With a very hold DVI monitor I cannot see anything. Then I moved to a
recent DVI monitor, but it hanged as well.
Then I recompiled CURRENT (updated to Thursday) and added several
printf to the EFI section (both boot1.efi and loader.efi).
I also updated the UEFI of the board to the most recent one, without luck.

I'll come back on Wednesday, I'll recompile everything removing all my
printf and let's see what happen.
Is the display so relevant?

Thanks again for the help, it's really appreciated!

Best regards,
pizzamig
