Re: MPLABX Suddenly started showing Target Device ID (0x0) is an Invalid Device ID
I am nowhere near as qualified as DevMod1, but I'll share my experiences anyways:
1 - Disconnect programmer, count to 10, reconnect programmer & try again.
2 - Disconnect programmer, shut down MPLABX, count to 30, reconnect programmer, count to 10, restart MPLABX & try again.
3 - Disconnect programmer, shut down MPLABX, count to 30, restart the computer, reconnect the programmer, count to 10, restart MPLABX & try again.
4 - I must have done something stupid (probably unintentionally) & fried the PIC. Figure out how in the blazes I fried the dang thing, correct the problem, replace the PIC, & try again.
5 - I have never solved a Target Device ID (0x00) issue by performing the Emergency Firmware Recovery process, but I do try it occasionally nonetheless.
6 - Contact Microchip, explain (IN DETAIL) what I've been doing, what I've been experiencing, and wait 2-4 days for their reply.
I don't need the world to know my name, but I want to live a life so all my great-grandchildren proudly remember me.
