Some bootloader's support hashing partitions. This is a great feature for testing
|
||
|
|
correctness. However, the format for the way the hash is returned depends on the
|
||
|
|
implementation. The hash could be send through an INFO response, or be as part
|
||
|
|
of the OKAY response itself. This script is called with the first argument
|
||
|
|
as the string mesage from the okay response. The second argument is each
|
||
|
|
info response joined by newlines into one argument.
