The following is clipped from one of my posts to the Microchip forums: It recently happened. I have been developing on a dsPIC30F2010 in the same target circuit for several weeks (hobby project). Using MPLAB 8.00 through the entire process. I have an ICD2 40 pin header board with ZIF socket and have tried 16F and 18F parts powered from ICD2. It will raise VPP to programming voltage and and hold the chips in reset. When releasing from reset the ICD2 VPP line only rises to approx. 1.8 VDC. I suspect the DG411 analog switch IC in the ICD2, whose purpose is switching the VPP line to the various voltages required. Any enlightenment is much appreciated although I fully understand that troubleshooting from afar is not ideal! -- Regards, Stephen D.
