I've tried various versions of P-ICD on various PIC devices and just can't seem to get it working, I'm obviously doing something wrong but I don't know what. I really would like to get a proper debugger like yours working for my next project. My only fall back is using MPLAB and my PicKit2 and I hate MPLAB, the UI is just awful.

The nearest I've gotten so far is with 18F14K50 and a blinky LED program and a physical (not USB CDC) COM port. The handshake icon is green and the serial icons says open and is green. The text "stepping, waiting for response ..." appears on the bottom left. On other times I've received the "wrong source" message.

Do you have a known good combination of PIC device, application program and the four binaries that make up P-ICD?

Is it worth doing a compete reinstall?

Unfortunately, I am limited to 18F4550, 18F2550, 18F14K50, 16F877A, 16F628A, 16F690 and 16F887.

BTW the default additional code for 18F14K50 sets both TX and RX to outputs.
