Was able to get openocd to work for NanoDAP and Pico2 but only wit the rasberry git. Checking out tag 0.12 from the openocd repo result in a calloc build error. Checking out openocd 0.12 master builds normally but executing gives a ROM mismatch. BTW after building openocd master branch the exe utable shows the version as dirty The raspberry git did not show this error and worked to flash the Pico2. Details here: https://github.com/wuxx/nanoDAP/issues/37 For those interested in Pico, this is a great blog post: https://admantium.com/blog/pico02_setup_debugging/ FWIW...

Do you have tcl scripts in sync with the compiled binary? Anyway use non modified source from our git before reporting an issue. Tomas
