JTAG Hat Turns Raspberry Pi Right into a Networked Debugger

During the last yr or so we’ve spotted a certain uptick within the collection of other folks the use of OpenOCD at the Raspberry Pi. It’s an affordable and handy answer for poking round with more than a few microcontrollers and embedded units, however now not all the time essentially the most chic. Having a look to toughen at the scenario relatively, (*5*) has been operating on a purpose-built JTAG Hat to scrub issues up just a little.(*8*)

Onboard degree shifters permit you connect with JTAG and SWD interfaces from 1.8 to 5 V, and when you energy the objective software from the Pi itself, there’s even enhance for measuring the voltage and present. To attach as much as your goal, the open {hardware} board includes a “legacy” pin header best possible for jumper wires, in addition to a devoted 10-pin Cortex Debug Connector. Whether or not you spin up your personal or purchase one assembled, it indubitably looks as if a device price having round when you incessantly in finding your self operating with the fitting chips.(*8*)

(*1*)Along with the design information for the {hardware}, [Matthew] has additionally supplied some great documentation on get the instrument aspect of items up and working. Beginning with a clean SD card, it walks you in the course of the preliminary setup of the Raspberry Pi during the set up and configuration of a patched model of OpenOCD designed to enhance the JTAG Hat.(*8*)

If you happen to spend extra time operating with 8-bit AVR chips, don’t concern. Closing yr we lined a equivalent challenge to show everybody’s favourite Linux SBC into an all-in-one microcontroller construction powerhouse.(*8*)
