mcbootflash 5.1.1

Flash firmware to devices running Microchip's 16-bit bootloader.

mcbootflash

Mcbootflash is a tool for flashing firmware to 16-bit Microchip MCUs and DSCs from the PIC24 and dsPIC33 families of devices, which are running a bootloader generated by the MPLAB Code Configurator tool.

Microchip provides an official GUI tool for this purpose, called the Unified Bootloader Host Application. Mcbootflash is intended to be a drop-in replacement, with some differences:

• No GUI
• Free and open source
• Written in Python instead of Java

Additionally, mcbootflash can be used as a library by applications which want to implement firmware flashing as part of a larger suite of features. See the documentation for details.

Installation

pip install mcbootflash
