# ESP32C3/S2-micropython-build

building ESP32C3/S2 micropython notes





Clone esp-idf repository; For ESP32-C3/S2 need V4.3.1+


> _git clone -b v4.4 --recursive https://github.com/espressif/esp-idf.git_ 





After you've cloned and checked out the IDF to the correct version, run the install.sh script:


> _cd esp-idf_ 


> _./install.sh_       # (or install.bat on Windows)


> _source export.sh_   # (or export.bat on Windows)


The install.sh step only needs to be done once. 


You will need to source export.sh for every new session. (For environment variables)


(Or $export ESP_IDF=~/esp_idf $source export.sh)





Clone MicroPython repository...


> _git clone https://www.github.com/micropython/micropython_ 


> _cd micropython/_ 


> _make -C mpy-cross/_ 


> _cd ports/esp32_


> _make submodules_


> _make BOARD=GENERIC_C3/S2 -j4_


> _cd build-GENERIC_C3/S2_


> _(or w/ USBCDC_


> _make BOARD=GENERIC_C3_USB -j4_


> _cd build-GENERIC_C3_USB)_





This will produce a combined firmware.bin image in the build-GENERIC_C3/ subdirectory


(this firmware image is made up of: bootloader.bin, partitions.bin and micropython.bin).


Project build complete. To flash, run this command:


> _esptool.py --port /dev/cu.wchusbserialfd130 write_flash -z 0x0 c3_firmware.bin_


> 


For ESP32-S2

> _esptool.py --port /dev/cu.wchusbserialfd130 write_flash --flash_mode dio -z 0x01000 s2_firmware.bin_


>


Thonny connectted to micropython w/ PyDOS.
