Good afternoon (o;
According to the "Bootloader and bootloadable datasheet" the application checksum is defined as:
"The basic summation checksum is computed by adding all the bytes (excluding the checksum) and then taking the 2’s complement ."
So for the SCB_Uart example it writes in the checksum field the byte 0x60...
But when I walk through the hex file and sum up all bytes I get "0x8F"...
Does "excluding the checksum" mean it includes the other meta fields at address 0x7FC0 as well like application length and so on?
Solved! Go to Solution.

Bootloader datasheet says
Bootloadable Application Checksum:
This is the basic summation checksum that is computed by adding all the bytes of the bootloadable application image (excluding the metadata section)
