    Bootloadable Application Checksum

      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?
