I am getting the error:
“No MBR signature found
barebox image seems not valid: Bad MBR signature”
At first I was trying it with OpenSuse and thought the problem could have
been related to it being 64-bit, however I am also getting the error on a 32-bit
build of Debian.
A hexdump of sdb does show “aa55” at the end of the 1st
sector.
