Flashing

CLI Flashing

In addition, you must install the esptool flashing tool:

https://github.com/espressif/esptool#easy-installation

Now you should be able to flash your board as follows:

Plug your ESP32-C3 board into your computer’s USB port.
Build and flash your TinyGo code using the tinygo flash command. This command flashes the ESP32-C3 with the serial example:
```
tinygo flash -target=m5stack-core2 examples/serial
```
The ESP32-C3 board should restart and then begin running your program.
