Can anything specific be gleaned from the error message:
It's from an 18M2, and I get the above message whenever I try to programme it in situ in a project board. Removing the chip and programming it in the development board (AXE091?) succeeds, but then the chip behaves nowhere near as expected when re-installed in the project board. I'm aware that verification errors are most commonly associated with power supply problems and I'll focus on that tomorrow when I start the fault finding, but if that error message points at something specifically then it's an advantage to know it. A quick measurement earlier showed the correct +5V on the 18M2 pin 14, and this supply is attached to a number of other boards containing 14M2s, all of which I have programmed without any difficulty.
?Error:
Verification error - 0xFFFFFF98 transmitted but 0xFFFFFFF0 received at byte 0
