Hi all,
I am trying to program PIC32MX795F512L [url]www.kynix.com/.../PIC32MX795F512L-80V/PT.html[/url]on by own board using PICKIT3. The schematic of the board is attached. [image]2.bp.blogspot.com/.../image] I am getting the following error when I select the programmer.
PICkit 3 detected Connecting to PICkit 3... Running self test... Self test passed Firmware Suite Version...... 01.25.10 Firmware type......................PIC32MX PICkit 3 Connected. Target Detected Target Device ID (0000e000) does not match expected Device ID (04307053).
I can see that the PIC is sending out some non-zero bits through oscilloscope on the PGD2 pin, and it is consistent over runs. Still MPLAB is giving the above all zero id error.
Also, if I program in release mode, I am getting success as mentioned below........ but the pic is not operational. I have tried in two separate boards but with no luck. Programming...Programming/Verify complete
My configuration bits are as follows
#ifndef OVERRIDE_CONFIG_BITS #pragma config UPLLEN = ON // USB PLL Enabled #pragma config FPLLMUL = MUL_20 // PLL Multiplier #pragma config UPLLIDIV = DIV_2 // USB PLL Input Divider #pragma config FPLLIDIV = DIV_2 // PLL Input Divider #pragma config FPLLODIV = DIV_1 // PLL Output Divider #pragma config FPBDIV = DIV_1 // Peripheral Clock divisor #pragma config FWDTEN = OFF // Watchdog Timer #pragma config WDTPS = PS1 // Watchdog Timer Postscale #pragma config FCKSM = CSDCMD // Clock Switching & Fail Safe Clock Monitor #pragma config OSCIOFNC = OFF // CLKO Enable #pragma config POSCMOD = HS // Primary Oscillator #pragma config IESO = OFF // Internal/External Switch-over #pragma config FSOSCEN = OFF // Secondary Oscillator Enable #pragma config FNOSC = PRIPLL // Oscillator Selection #pragma config CP = OFF // Code Protect #pragma config BWP = OFF // Boot Flash Write Protect #pragma config PWP = OFF // Program Flash Write Protect #pragma config ICESEL = ICS_PGx2 // ICE/ICD Comm Channel Select #pragma config DEBUG = OFF // Debugger Disabled for Starter Kit #endif // OVERRIDE_CONFIG_BITS
Another observation: When I check OSC2 pin through oscilloscope, I see an oscillation@7MHz instead of 8MHz. Any idea on why the frequency is decreased will be of great help. I have attached a snapshot of the board too for your reference. Hope to get some light from the masters... Thanks in advance

What architecture that is supported by Keil would you select for that part?
