I'm curious... Would it be possible to "misuse" the i2c/twi bus for this as well? I couldn't find someone doing that yet. Because it's already a two-wire interface it's perhaps more readily available on hardware. Are their particular difficulties with such an approach that you foresee?
This is a preliminary informational request. I might implement it later after I've looked into it more and I get some first feedback on the idea from an expert like you.
Hi, very nice also the post on https://www.pcbway.com/blog/technology/OpenOCD_on_Raspberry_Pi__Better_with_SWD_on_SPI.html / https://lupyuen.github.io/articles/openocd-on-raspberry-pi-better-with-swd-on-spi
