Open-source SWD programming adapter

Monday, February 29th, 2016

Ethan Zonca from Protofusion writes, "After making the switch from AVR to STM32 microcontrollers, I redesigned my old 6-pin ICSP pogo-programming adapter for SWD. The new design allows programming with pogo pins or a small pin header soldered to the pogo pads for debugging, all with the same cable. The...

Introduction to cortex serial wire debugging, 3-part tutorial

Monday, November 26th, 2012

Squonk refers us to this 3-part tutorial on the ARM SWD debug protocol. LPC ARM Cortex-based microcontrollers from NXP can be controlled via SWD, ARM’s Serial Wire Debug protocol and the Coresight register set which allow nonintrusive debugging. This blog post series summarizes use of the SWD protocol to do...
