Changing one word in Flash with CCS Device Programmer

Colleagues,

The previous generation of CCS Device Programmer allowed direct modification of PIC’s Flash memory. I.e. it was possible to write 0x0001 to address 0x7FFF after downloading the firmware hex file. In an old project I was using this feature to hack serial numbers into devices (then the serial number was accessible through read_program_memory() ).

I can’t seem to find this feature in the most recent generation of CCS Device Programmer (currently, I have 4.025 and ICD-U64). Is it still there Question

Conceivably, it was removed from GUI, but still available through command line. Is there a way to modify one byte in Flash Question

Any suggestions, references, or insight are appreciated!

- Nick

P.S. Moved this topic to ICD forum from the General forum.

According to CCS support (I've called them), random access to Flash from CCSload is on the todo list of features.
