At what offset is the barebox partition you apply the barebox update to?
If the barebox partition offset is not at the very start, try setting offset
to zero.
Not sure about the i.MX7 specifically, but for other i.MX*, the image already
contains padding at the start, so it can directly be written to the medium, unlike
U-Boot, which needs to be written at an offset.
