Espressobin anyone ?

[Søren Schmidt]

Hi

That does the trick, I now have my SDcard found and can boot and run from it.

However, there is still the problem with currdev not be set. I instrumented the loader a bit:

Consoles: EFI console  
    Reading loader env vars from /efi/freebsd/loader.env
efiblk_get_pdinfo_by_handle failed
stat /efi/freebsd/loader.env failed
FreeBSD/arm64 EFI loader, Revision 1.1

However the file is there and readable:

/efi/boot:
total 16
-rwxr-xr-x  1 root  wheel  15946 Jun 10 14:29 armada-3720-espressobin.dtb

/efi/freebsd:
total 536
-rwxr-xr-x  1 root  wheel  543176 Jun 10 14:29 loader.efi
-rwxr-xr-x  1 root  wheel      16 Jun 10 14:29 loader.env


Setting it manually to disk0p2 makes boot possible.

Also I needed this patch to get t he SATA driver detected, otherwise it fails with error 6.

Both are easily worked around, and I can get on with the project this was acquired for, thanks for getting this fixed!

Any plans to get it MFC’d back to 12stable ? Otherwise I might look into that as that’s what we use here…
