Sorry this took so long, here is the code as a component: https://github.com/PaulFreund/libSWD-esp32 It should be able to use all features of libSWD, I only tired to read the ID code and memory data by address so far. I tested successfully with up to 40Mhz and because of the handy 3-wire mode in the...

PS: I will publish some code in the following days

I got it to work! Without hardware hacking :) The SPI master has a 3-Wire mode. To add frosting to the cake it is implemented to a level that allows memory/flash reading and writing with ready made functions thanks to the work of libSWD! Next topic for me is to investigate if I can use urJTAG and if...

thank you very much for your description! I will definitely update you with my progress

I would like to use the ESP32 as a debugger to read and write memory/registers and maybe debug other connected processors. I see different ways of achieving this, depending on what the peripherals of the ESP32 allow and here I would like to have your feedback. SWD has its similarities to SPI (see ht...
