Easy-loader uploads application hex files to either the 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.

Easy-loader is installed from source.

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

Typing easy-loader alone will output the following help.

The device can either be a serial interface of CAN Bus interface. Support for CAN Bus is boot loader dependent and this is not available for Oxford boot loader at present.

Here a device attached to RPi is first reset using `pctrl restore' and the a hex file image is uploaded at 57600 baud.
