True. What we would need to make it simple :
- have arithmetic expressions in hush
- have a "dd" command with options skip,bs,count
=> that is actually a requirement to flash (as cp uses blocks of 4096, while
flash with oob wants block of writesize+oobsize which are seldom multiples of
512).
I was thinking that a "dd" command would be handy. Would you accept it in
barebox ?
Cheers.
