Reprogram PIC18F4525 without erasing EEPROM using Load-N-Go
PostPosted: Thu Jan 14, 2010 3:40 am     Reply with quote
I just purchased a Load-N-Go. I need to perform on-field reprogramming for our security product. There is calibration data stored on the data EEPROM and I would like to reprogram the PIC18 without erasing the data EEPROM. No code protection was use on the PIC18.

However, I am not able to reprogram the PIC18 without erasing the data EEPROM. How do I set the CCSLOAD? or do I need to modify the exported HEX file from MPLAB? Pls help. Thanks!

Hi, Did you manage to program the flash without programming the data EEPROM? Thanks.
