That bit is.

The function takes two parameters, in $1 and $2 at the start.
The first parameter, copied into p, is the partition number,
and so it needs to go 0, 1, ...
perhaps_write_flash 0 224
perhaps_write_flash 1 16
perhaps_write_flash 2 16
perhaps_write_flash 3 16
perhaps_write_flash 4 1728
perhaps_write_flash 5 48
I also think you might want to remove the `-backup' in f's definition
near the start because your script said they were called e3-nand.0, etc.
What you've given here replaces the six blocks of if...then...fi lines
in your original script, leaving the bit before and after.

Cheers, Ralph.
