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
