Pic32prog is a utility for loading data into a flash memory of Microchip PIC32 microcontrollers. Supported adapters and protocols:

• Microchip PICkit2
• Microchip PICkit3 with scripting firmware (use Scripting Tool to upgrade)
• AN1388 HID bootloader
• Legacy FS_USB HID bootloader
• Olimex ARM-USB-Tiny JTAG adapter
• Olimex ARM-USB-Tiny-H JTAG adapter
• Olimex ARM-USB-OCD-H JTAG adapter
• Olimex MIPS-USB-OCD-H JTAG adapter
• Bus Blaster v2 JTAG adapter from Dangerous Prototypes
• Bus Blaster v3c for MIPS
• Flyswatter JTAG adapter from TinCanTools
• Arduino-compatible bootloader (stk500v2 protocol)
• mikroE MINI-32 bootloader (UHB protocol).

Usage

When called without parameters, pic32prog utility detects a type of microcontroller and device configuration. For example:

% pic32prog
Programmer for Mictochip PIC32 microcontrollers, Version 1.0
    Copyright: (C) 2011 Serge Vakulenko
      Adapter: PICkit2 Version 2.32.0
    Processor: 795F512L (id 04307053)
 Flash memory: 512 kbytes
Configuration:
    DEVCFG0 = 7ffffffd
                     1 Debugger enabled
                     8 Use PGC2/PGD2
    DEVCFG1 = ff6afd5b
                     3 Primary oscillator with PLL
                   1   Primary oscillator: XT
                   4   CLKO output active
                  3    Peripheral bus clock: SYSCLK / 8
                  4    Fail-safe clock monitor disable
                  8    Clock switching disable
                 a     Watchdog postscale: 1/1024
    DEVCFG2 = fff8f9d9
                     1 PLL divider: 1/2
                    5  PLL multiplier: 20x
                   1   USB PLL divider: 1/2
                  8    Disable USB PLL
                       Enable USB PLL
                 0     PLL postscaler: 1/1
    DEVCFG3 = 3affffff
                 7     Assign irq priority 7 to shadow set
                       Ethernet RMII enabled
               2       Default Ethernet i/o pins
                       Alternate CAN i/o pins
                       USBID pin: controlled by port
                       VBuson pin: controlled by port

Writing to flash memory:

pic32prog [-v] file.srec
pic32prog [-v] file.hex

Reading memory to file:

pic32prog -r file.bin address length

Parameters:

• file.srec - file with firmware in SREC format
• file.srec - file with firmware in Intel HEX format
• file.bin - binary file
• address - address in memory
• -v - verify only (no write)
• -r - read mode

Input file should have format SREC or Intel HEX. You can convert ELF format (also COFF or A.OUT) to SREC using objcopy utility, for example:

objcopy -O srec firmware.elf firmware.srec

Olimex JTAG adapter

Olimex ARM-USB-Tiny JTAG adapter is equipped with 20-pin connector:

PIC32-based boards usually use 14-pin JTAG connector:

The cable:

JTAG-Tiny	PIC32 board	Signal
3	1	/TRST -- yellow/blue
4	2	GND -- black
5	3	TDI -- yellow
7	7	TMS -- blue
9	9	TCK -- green
13	5	TDO -- red
15	11	/RST -- yellow/red
