Hi

CCS-IDE with ICD-U64.

Is it possible to prevent EEprom form erase, when programming from CCS-IDE with ICD-U64? If it is, how to?

I had this same problem with 18FxK22 series and contacted CCS about it. According to Darren Rook, this is an issue with the chip itself, not the programmer.

On their actual programmers (like the Mach-X), the setting is 'inherited'. You run up CCSLoad, and and untick the option in this for 'data EE', and 'config bits'. Then exit, and run from inside the IDE, and it then doesn't erase the EEPROM. Problem is that if the config bits are selected, it has to do a full erase, so it can't then save the EEPROM.
Don't know if the same applies with the U-64, but it might be worth investigating.
