Adding my own libraries to the firmware

[liquikitten]

Hello, I encountered a problem combining the firmware with my .bin file. My .bin file contains .mpy scripts (made using mklittlefs). I was guided to combine this by this site https://docs.espressif.com/projects/esptool/en/latest/esp32s3/esptool/basic-commands.html
The problem is that when flashing the merged firmware, I cannot use my libraries, because for some reason they are not displayed in the list of available libraries. How can I properly add my libraries to micropython firmware?

The usual way of embedding modules in a firmware build is documented here.

I tried this method, but I got the following error when assembling

You have to set up the build environment for ESP32 properly as detailed in esp32/README.md. Note that you have to update the submodules in the esp-idf directory after checking out the esp-idf version and to run the install script. That's all documented in README.md. When that's done you can change back to the micropython/esp32 directory.
idf.py is located in <esp-idf_dir>/tools. Make sure that this is in your PATH. To set the proper paths, I run . <idf_dir>/export.sh.
