Flashing

CLI Flashing on Linux

You need to install the Espressif toolchain for Linux to use TinyGo with the ESP32:

https://docs.espressif.com/projects/esp-idf/en/release-v3.0/get-started/linux-setup.html#standard-setup-of-toolchain-for-linux

In addition, you must install the esptool flashing tool:

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

• Plug your ESP32 board into your computer’s USB port.

• Build and flash your TinyGo code using the tinygo flash command. This command flashes the ESP32 with the serial example:

  tinygo flash -target=m5stack -port=/dev/ttyUSB0 examples/serial
  

• The ESP32 board should restart and then begin running your program.

CLI Flashing on macOS

You need to install the Espressif toolchain for macOS to use TinyGo with the ESP32:
