Serialization
The general procedure to write a serial number to a Flash device involves the following
steps:
1. Choose a location for the serial number inside or outside of the address range defined
in the hex file.
NOTE: The serial number must be written to a location that is not being written to by the
hex file.
2. Erase the Flash device.
3. Write the hex file to the Flash device and then write the serial number
or
write the serial number to the Flash device and then write the hex file.

2. Select the Enable check box.
3. Type the start value for the serial number in the Serial Value field and select the Dec

4. Type the location you want the serial number located in the Address Hex field.
