@Urhengulas I've got an ST Link JTAG programmer and an ESP32, would love some tips on testing this out!

Sure!

1. Install your local probe-run

   $ cd path/to/probe-run
   $ cargo install --path .

2. Set up the https://github.com/knurling-rs/app-template for your board
3. Add the --verify option to the runner in .cargo/config.toml (link)
4. Then just run a few of the examples, e.g.:

   $ cargo rb hello

5. Try it in combination with some of the other configuration flags, e.g. --measure-stack, --no-flash, --connect-under-reset
6. If that behaves as expected you can mark the PR as ready for review.

PS: Please add the change to the CHANGELOG.md.

@Urhengulas Turns out the ST Link debuggers don't work with the ESP32 https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/jtag-debugging/index.html#jtag-debugging-selecting-jtag-adapter

Would it be possible to test this out on your end?
