This app is dedicated to programming your micro controller and nothing else. It starts up fast, programs reliably and gets out of your way.


Allows flash programming over a RS232 serial connection. No need to break out the JTAG programmer.

Easy to use

Select a port, choose your firmware and you're ready to program. The app also remembers which serial port and firmware file you last used and loads them on startup.

Select a Serial Port

Works well with modern USB serial converters. Handles ports being added and removed gracefully.

Identifies the processor for you

No more picking your processor model out of a popup list. Bootstrap Bill interrogates your processor and chooses its settings appropriately.

Chose your firmware

Reads files in Intel HEX format (default output from IAR Compiler Suite)

One click Programming

All settings are remembered between application relaunches so all you have to do is start Bootstrap Bill and hit Program.
