Electronic – Programming Pins (PGC/PGD) problem on PIC32mx

microchipmicrocontrollerpic

I made a design using PIC32mx and everything is working well. I was trying to debug my first program and for this case instead choosing PGEC1 and PGED1 I am using PGED2 and PGEC2. Problably that's the reason why I am getting the following message while debugging:

The target device is not ready for debugging. Please check your configuration bit settings and program the device before proceeding. The most common causes for this failure are oscillator and/or PGC/PGD settings.

This is the schematic I have done:

Where can I modify the configuration bits to enable the debug mode?

The sentence to enable the debug mode for my case is:

#pragma config   ICESEL = ICS_PGx2

Electronic – PIC12F617 Device ID read when debugging but not when programming

Your circuit looks fine. The 51.1 kΩ resistor and diode to Vdd on MCLR is a bit silly, but that's not getting in the way of the ICD reading the device ID. Two things to consider:

Make sure that you are trying to use the ICD3 as a programmer, not a debugger when you are just trying to program firmware that should stand on its own.
Maybe you are getting crosstalk between PGC and PGC? I usually put 100 Ω in series with the lines coming out from the PIC, followed by 47 pF or so to ground. That filters sharp edges the PIC can produce during readback, which can cross between the two lines. This is made worse by PGC and PGD being next to each other on the normal ICD cable. I often use a ribbon cable with a extra ground line between the two.
