Electrical – Programming USB OTG PIC32 through USB in MPLAB

I have a PICKIT2 and there are some devices that it can program if you use the standalone PICKIT2 software but which it can't program from within MPLAB. It looks like the situation is the same for your device with pickit1.

If you look at the release notes for MPLAB it has a file for supported devices (On my machine it was stored at C:/Program Files (x86)/Microchip/MPLAB IDE/Readmes/Device Support.htm). That file indicates that specific PIC device is NOT supported for programming with a PICKIT1 using MPLAB.

And yet the PICKIT1 documentation does indicate that device is supported for programming.

Does the pickit1 come with a standalone programming program like pickit2 does? If so you can probably use that to upload the .hex file to it

You have to set the configuration bits. Near the end of the device's header file (line 5880 for dsPIC30F4013) is a listing of all the device's configuration bits that need to be set or cleared to ensure proper operation of the device, as well as code comments for how to do it.

For example:

_FOSC( XT & CSW_FSCM_OFF )  // Configure for external XT crystal oscillator, turn off clock switching and monitoring

The oscillator and watchdog timer configurations are very important.

EDIT: In your edited post you tried using the phase-locked loop option for the oscillator. You have to add the following code in your main routine in order to use an external oscillator + PLL:

/*
 *  Set up the PLL for full 60 MIPS operation (dsPIC33EP512MU810)
 *
 *  Fcy = Fin*K/2 --> 60MHz = 8MHz*K/2 --> K = 15
 *  K = M/(N2*N1) --> 15 = M/(N2*N1)   --> N2 = 2, N1 = 2, M = 60
 *  Fcy = 8MHz*15/2 = 60MHz
 *
 *  p. 164-171 datasheet

void configPLL()
{
    PLLFBDbits.PLLDIV = 58; // M = 60
    CLKDIVbits.PLLPOST = 0; // N1 = 2
    CLKDIVbits.PLLPRE = 0;  // N2 = 2
    OSCTUN = 0;
    // Writing to the OSCCON register requires a special unlock sequence
    // Using a compiler built-in write instruction to handle this
    __builtin_write_OSCCONH(0x03);  // Select primary oscillator with PLL   
    __builtin_write_OSCCONL(0x01);  // Request oscillator switch
    while (OSCCONbits.COSC != 0x3); // Wait for the PLL to lock
}
