Hello,

Please incrementally bring additional components (e.g. xmodem) one-by-one into minimal application. This would allow to understand issue quickly. If problem persists please help to share minimal application and I will take a look.

Reference pointer I had provided was actually component hosted in an independent repository and used as git submodule within main IDF repository. Alternatively you may also use `EXTRA_COMPONENT_DIRS` to specify path to extra components and that way they can be easily shared among projects or applica...

You can put it as submodule within `components` directory of your project/application.

For example: https://github.com/espressif/esp-idf/tr ... components

Hi Tibi Documentation pointer at https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/build-system.html#multiple-components-with-the-same-name can be helpful for you. Idea here is to duplicate component within your project under `components` directory, and it shall take preference ...
