Use Case:
Use the ESP32 IDF Docker Image from Espressif and create binaries for the ESP32-Lyradt Boards. The Docker Image will be used interactively.
The ESP32 ADF will be local on the Linux Host.
We get the ADF Environment with the command:
git clone –recursive https://github.com/espressif/esp-adf.git
Mount a local host directory inside Docker Image
docker run –rm -v $PWD:/project -w /project -it espressif/idf
Access USB port /dev/ttyUSB0
sudo docker run –rm –privileged -v $PWD:/project -w /project -it espressif/idf
or (more secure)
sudo docker run –rm –device=/dev/ttyUSB0 -e ADF_PATH=/project -v $PWD:/project -w /project -it espressif/idf
With Env Var like ADF_PATH
sudo docker run –rm –privileged -e ADF_PATH=/project -v $PWD:/project -w /project -it espressif/idf
Available commands:
idf.py build (build with CMake)
idf.py flash
idf.py monitor
xtensa-esp32-elf-gcc --version
make -version
cmake -version
make menuconfig
make && make flash monitor (build with GNU Make)
Flashing:
idf.py flash If you have problems then push "Boot" Button and "RST" Button and release first the RST Button.
