hi Jennie,

sorry, i had to work on a other Projekt last time. But now it goes on with this

Thats not what i mean. At Microchip you can read and write the EEprom on the chip with the tool. So you can control what you controller had written or you can write spezial start defines

Hi Thorsten.

EEPROM is read-only space.EEPROM data can be read out in debugger but can not be written with debugger tool.

See attached video of how to read EEPROM data from debugger.

Have a great day,
