Flashing
CLI Flashing on Linux
You need to install the same toolchain for the ESP8266 as is used for the ESP32 to use the ESP8266 with TinyGo:
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 ESP8266 board into your computer’s USB port.
-
Build and flash your TinyGo code using the
tinygo flashcommand. This command flashes the ESP8266 with the blinky1 example:tinygo flash -target=d1mini -port=/dev/ttyUSB examples/blinky1 -
The ESP8266 board should restart and then begin running your program.
CLI Flashing on macOS
You need to install the same toolchain for the ESP8266 as is used for the ESP32 to use the ESP8266 with TinyGo:
