Bumpy blackmagic probe compatible SWD debugger

What is Bumpy?

Bumpy is an inexpensive Open Source blackmagic probe compatible SWD debugger designed to be used with ARM GDB. It supports many platforms, but was primarily designed for use with our Nordic Semiconductor nRF BLE boards.

When we built our Bluey nRF52 BLE dev board, we were looking for an inexpensive option for our users to upload code to bluey and debug it using ARM GDB. We then came across the blackmagic probe (BMP) project - an Open Source debugging tool for embedded microprocessors. It greatly simplifies the debugging and code uploading process using just ARM GDB - no need to run a GDB server or use an additional complex tool like openocd. Although the BMP hardware is excellent, it's bit beyond the budget of our target audience as an add-on programmer. So we decided to make use of their liberal open source license and build something that fits our budget, albeit with less capabilities.

Bumpy takes advantage of the ST-Link support of the BMP, and its design is based on both BMP and Chinese St-Link V2 clones available for cheap in the market.

What can you do with Bumpy?

You can use Bumpy to program and debug a whole bunch of ARM microcontrollers. In particular, Bumpy is perfect for programming out Bluey nRF52 dev board.
