I need to compute the checksum for a firmware image and I'm looking for suggestions on what works best.
I'm using SES and I don't see any checksum or CRC of the firmware image displayed after building the project.
I found that the SEGGER J-Flash software will compute a CRC of the data, but it seems to be broken as I can't
make it compute only the application flash region, even after deselecting the UICR region. But this is a separate
issue. I'd like to know what methods people generally use to compute a checksum.
