OpenOCD broken / missing
According to the documentation of the ESP-IDF[1], it should contain an ESP32 compatible version of OpenOCD.
However, qthing seems to lack this feature:
[fxk8y@mooshroom:~/git/subraum/qthing_TheNewAndFancyOne]$ openocd --version
The program 'openocd' is not in your PATH. You can make it available in an
ephemeral shell by typing:
nix-shell -p openocd
[fxk8y@mooshroom:~/git/subraum/qthing_TheNewAndFancyOne]$ find . -iname openocd
[fxk8y@mooshroom:~/git/subraum/qthing_TheNewAndFancyOne]$
[1]: ESP-IDF / OpenOCD:
If you have already set up ESP-IDF with CMake build system according to the Getting Started Guide, then OpenOCD is already installed.
