idf.py monitor doesn't connect #62

Closed hampa closed 2 years ago

hampa commented 2 years ago

I'm trying to use the command idf.py flash monitor or just idf.py monitor.

It always fails. I can flash properly but just not monitor.

Any hints on what the problem is?

My binary is too big or something? I've changed so that it loads Void as default.

Seemingly there is a compatibilty issue between the version of OSx you are using the version of espidf / idf.py used. As described in the error-output by: dlsym(RTLD_DEFAULT, kIOMasterPortDefault): symbol not found

Here is a link, dating back to 2020 which at least describes a possible bypass-solution by changing the call to idf.py as well as commenting out some lines in it: https://github.com/espressif/esptool/issues/540

Yes, that was it.

Upgrading espressif worked.

Hi, cool to hear about that. And if everything is working with the new ESP-Toolchain that's perfect of course. Just one hint on that, I once ran into other problems regarding the ESP IDF Filesystem when using another version. According to: https://github.com/ctag-fh-kiel/ctag-tbd "git checkout release/v4.1" version 4.1 still is recommended. So in other words: if you every should run into other problems with that environment you may have to do a fallback and patch idf.py by yourself to make it work. But hopefully of course this will not happen - just saying because of my own experience ;-)
