Our production requirement for Flash programming of the luminary LM3S618 is to add a Board serial number at location 0x7FFC during production programming on our Teradyne In-Circuit test system using the Flasher ARM in the standalone mode. To do so I have attempted to use the #FWRITE ASCII command and modify the Flasher.dat file prior to programming the device. The problem is that when I initiate the #AUTO command I get the error "Invalid Checksum of data block in file". I assume that there is a CRC value for the file that is checked prior to the write. Is there a location in the Flasher.dat file that I can modify according to the modified bytes at 0x7FFC that I can also modify to allow me to write my data?
