Program your board using the esptool.py program, found [here](https://github.com/espressif/esptool). If you are putting MicroPython on your board for the first time then you should first erase the entire flash using: ```bash esptool.py --chip esp32s3 --port /dev/ttyACM0 erase_flash ``` From then on program the firmware starting at address 0: ```bash esptool.py --chip esp32s3 --port /dev/ttyACM0 write_flash -z 0 board-20210902-v1.17.bin ```
