=== Usage ===
When called without parameters, pic32prog utility detects a type of microcontroller
and device configuration. For example:
% pic32prog
Programmer for Microchip 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
