Instructions

You need to have some dependencies pre-instaled in your OS:

  • Python 3
  • Pip
  • Python VENV

Then Flash:

  • Put 3 binaries in the same folder you are executing the steps, example Downloads folder, you need to be in that folder where are the binaries.
python -m esptool --chip esp32c3 -b 460800 --before default-reset --after hard-reset write-flash --flash-mode dio --flash-size 4MB --flash-freq 40m 0x1000 bootloader.bin 0x8000 partition-table.bin 0x10000 micropython.bin

Linux:

python -m venv esp-env
source esp-env/bin/activate
