#172167 - I'd suggest you focus on the datasheet Responding to: ???'s previous message |
You must find the precise differences between the MCU you used in the past and the one you're using now. Does the one you want to use now even allow IAP in the lower 8kBytes of program memory (0x000-0x1FFF)?
I would suggest you specifically look for the details that Jan has recommended you consider. RE |
