Jeff Probe - Open Source JTAG by Flirc

Jeff Probe is an open source JTAG probe based entirely off the popular black magic probe. We needed a cost effective solution for in house debugging, the ability for customization, and something we can include on test fixtures. We leveraged our volume and made Jeff Probe in hopes to give back to the community and give students an opportunity to get an affordable JTAG solution. Unique feature for 2 wire serial interfaces, allows unused JTAG pins to route UART for single wire connection. Shows up as two USB interfaces, one as the GDB server, one as the UART to the slave device.
