Hi Team,
I am using the flash kernel project and the serial flash programmer in order to update the firmware in CPU1 flash.
I have changed #define checksum_enable to 0 in the serial_flash_programmer project and the Device Firmware Update function fails (it was succesful before this change).
This is the error message that I get:

I have also changed #define checksum_enable to 0 in the flash kernel project.
Does the checksum need to be enabled in order to work? I disabled it in order to speed up the DFU.
