Sounds like another point for a bootloader. And I now really agree with the point you have in the ZPL documentation about not messing with the 18F config bits even though they are writable. > > But for the argument 'but I use a HVP programmer and my image has LVP > disabled': note that when you reprogram the part you will likely erase > it as part of the programming process. And the erased state of the LVP > bit is? LVP on! As I said above I'm clear on the LVP pin problem when programming. So the new wrinkle is ICSP. Even when doing HVP only via ICSP one must make sure that the LVP pin doesn't float. Crystal clear now.
