Has anyone ever tried this kind of thing?

"This application note provides C functions for accessing the Flash memory using the Self programming..."

isnt self programming what the bootloader does?

Yes. Reading tbe app note more, it says the FLASH writing must be done from within the Boot section of memory. Not what I thought it was going to be.

what we all want it to be heh :wink:
