CCS ICDU64 and MPLAB ?

[soonc]

The saga moves on.

I'm trying to get PIC24FJ128GA306 to do oscillator switching in debug mode.

I got the MicroChip ICD-3 as I'm told it can (may) switch oscillators while in debug mode.

I installed MPLAB 8.92 (recommended rather than MPLAB-X) and setup the CCS plug in.

I have loaded my project, compiled, but then MPLAB complains

Target Detected
ICD3Err0086: Target Device ID (fff80000) does not match
expected Device ID (46c20000). If you experience persistent
problems communicating, the ICD 3 test interface can be
used to help diagnose the problem.

Prior to using the ICD-3 I was using the ICDU-64 successfully doing a lot of debugging (until this clock switching issue popped up) and as the ICD-3 and ICDU-64 use the same RJ pin out, so I expected the debugger to run the code.

Just to test my setup I loaded my project in PCWHD and can still run the code with the ICDU-64 so I'm convinced the wiring is good.

Power is clean and in MPLAB Menu/Debugger/Settings/Status the Voltages are:-

ICD 3 VPP 3.25
ICD 3 VDD 3.45
Target VDD 3.29

Any tips as to what I'm doing wrong would be appreciated.

Your title is misleading. Your post is about ICD3 and MPLAB.

Check the ICD3 poster.

Make sure you do everything it says to do, and not to do.
- MCLR resistor between 4.7K and 10K. (10K is the usual value).
- AVdd and AVss pins connected to power and ground on the PIC.
- No components connected to the PGC and PGD pins on the PIC.
- First test it with MPLAB set to Release mode. Then try it in Debug mode.
- Check all connections with an ohmmeter.
- Test the ICD3 with the included self-test header.
- Use as short a cable as possible between the ICD3 and the PIC.

If that doesn't work, enter a trouble ticket on the Microchip forum.
