Easy-loader for Cowboy, Wellington and Oxford boot loaders

oxford2.jpg

Easy-loader uploads application hex files to either the Cowboy boot loader for enhanced PIC12/PIC16, Wellington boot loader for PIC18 or Oxford boot loader for dsPIC/PIC24.

Easy-loader also has a number of options to interrogate the boot loader to inspect chip flash and EEPROM content.

Install

Easy-loader is installed from source.

hg clone http://hg.kewl.org/pub/easy-loader
cd easy-loader
make
sudo make install

Usage

Typing easy-loader alone will output the following help.

USAGE: easy-loader [OPTIONS] DEVICE [HEX-FILE]

Invalid args.

Options:
 -a     arduino (DTR + CAP) reset
 -b N   use TTY baud rate N
 -d     hang up DTR after serial port open
 -e     read EEPROM
 -f     read flash
 -h     HELLO only
 -i N   use CAN bus message id N
 -k N   send BRK for N ms after serial port open
 -l H|R log serial input when done (H = hex, R = raw)
 -n     do not run firmware on exit
 -p     run pickle pctrl to reset device
 -q     quiet erase/write
 -r     hang up RTS after serial port open
 -s     simulate erase/write
 -t     time to wait in ms after serial port open
 -v     verify
 -w N   winklepicker mode N (1 or 2) reset
 -x     drain serial output after each transmitted byte
 -z A   erase page at address A

Version: 4

The device can either be a serial interface of CAN Bus interface. Support for CAN Bus is platform and boot loader dependent and is only available for Linux and the Wellington boot loader at present.

Example

Here a device (which is attached to an RPi) is reset using `pctrl restore' and then a hex file image is uploaded at 57600 baud.

easy-loader -p -b 57600 /dev/ttyAMA0 myapp.hex
