EEPROM DATA UPLOAD VIA BOOTLOADER on PIC18
PostPosted: Fri Feb 17, 2006 6:23 pm     Reply with quote
Hi,
i wrote my own bootloader for PIC18.
I know that EEPROM data are "mapped" starting at 0xF00000 ...
my bootloader read the .hex file and write the data via the
WRITE_PROGRAM_MEMORY function.
now, all right with programs data, impossible to write the location from 0xf00000.
Are this locations writeble only in program mode (with VPP applied) ???

Thanls in advance for the help

Regards

Mauro

You can always write to eeprom, you don't need to apply Vpp.
Just remember that for writing to program Flash memory you use the function Write_program_memory(), for EEPROM use the function write_eeprom().
