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.
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.
We have a bunch of documentation at the link below, which can get you started with Bumpy:

We recognize our top users by making them a Tindarian. Tindarians have access to secret & unreleased features.
We look for the most active & best members of the Tindie community, and invite them to join. There isn't a selection process or form to fill out. The only way to become a Tindarian is by being a nice & active member of the Tindie community!
Electronut Labs started as a blog on Electronics and Programming. After a long career in the software industry, Mahesh Venkitachalam wanted to return to his childhood interest in building electronic gadgets. The projects and articles in the blog gained in popularity, culminating in a book with elements of programming and hardware (Python Playground, No Starch Press).
Today, Electronut Labs is a company based in Bangalore. We offer consulting services in Embedded Systems design – helping companies bring their ideas in hardware to market. We are also big proponents of Open Source and education, and our maker products and training courses cater to this market. Our passion for hardware ensures that we’re not just content to build for others – we have our own line of well designed, useful products which keeps us at the cutting edge of technology.
