Debugging Pinguino-MX220 w/ MPLABX and PICkit 3

[andersm]

I'm trying to write code for the Pinguino-MX220 board using MPLABX 1.6 and XC32 1.2, using a PICkit 3 for programming, and while programming the flash works just fine, trying to debug just results in the error message "The target device is not ready for debugging. Please check your configuration bit settings and program the device before proceeding." Has anyone managed to use this combination successfully? My config bit settings are as follows, using just the FRC or FRC/16 as system clock didn't help.

Hi,
I have exactly the same problem.

Program and run fine in release mode but can't debug

Connecting to MPLAB PICkit 3...
Firmware Suite Version.....01.28.40
Firmware type..............PIC32MX
...
Programming...
Programming/Verify complete
The target device is not ready for debugging. Please check your configuration bit settings and program the device before proceeding.

My PicKit3 is a sure clone but i don't know if it's the pb

here are the pragma i used :

#pragma config FPLLMUL = MUL_20, FPLLIDIV = DIV_2, FPLLODIV = DIV_2
#pragma config FPBDIV = DIV_1
#pragma config POSCMOD = HS, FNOSC = PRIPLL
#pragma config FWDTEN = OFF
#pragma config FSOSCEN = OFF
#pragma config IESO = OFF 
#pragma config JTAGEN = OFF
#pragma config DEBUG = ON
#pragma config ICESEL = ICS_PGx3

Do you resolved it ?

[andersm]

Unfortunately not. I've tried using ICS_PGx1 as the debug port, but that made no difference. It would be nice to know if it's a bug in the PICkit firmware or the chip, but I don't really have the equipment to figure that out. I doubt it's an issue with the board, as it seems to follow the guidelines to a t and works fine otherwise. I filed a support request with Microchip, but have had no reply.

[andersm]

The same PICkit could debug a PIC32 USB Starter Kit 2 board without problems, so it's not the problem. I also tried using a clone PICkit 3 with the Pinguino board, but it failed with the same error (I guess it's a good clone then!)

[andersm]

At the suggestion of Microchip's support I went back to MPLAB X 1.51, and after downgrading to PICkit 3 firmware 1.28.18 debugging was working. Hopefully they'll release an updated version of MPLAB X with a fixed firmware soon!

Hello,

Maybe, you can try:

#pragma config ICESEL   = ICS_PGx1
#pragma config DEBUG    = ON

MPLAB X 1.7 includes PICkit 3 firmware version 1.28.57 which fixes this problem.
