56F84763, firmware update, Bootloader, SDM

Currently I'm working on a field update for our 56F84763 processors.

And right now I have a problem with the flashing of the device.


Our project is small, so we work with the SDM.

For the flashing I load the flash routine in the program memory RAM of the device. Which is outside the addressable memory space in SDM.

Sometimes the flashing works, sometimes it does not. I don't know if its the fault of the actual code or some restrictions in the device.


My actual question is: do the limitations of the SDM (i.e. 16 memory addresses) only apply for access in data memory? Or does the same apply for program memory?

I'd be happy if someone could point me at the right document. I found lots of bits an pieces, but its hard to get the full picture.


Thanks and best regards,
