Arduino MKR WiFi 1010
The Arduino MKR WiFi 1010 is a very small ARM development board based on the Microchip SAMD21 family of processors. It also has a NINA-W102 chip onboard which provides an wireless communication abilities based on the popular ESP32 family of wireless chips from Espressif.

In order to flash your TinyGo programs onto the Arduino MKR WiFi 1010 board, you will need to install the “bossac” command line utility which is part of the BOSSA command line utilities.
You can use Homebrew to install the BOSSA command line interface by using the following command:
brew install bossa
Or if you prefer, you can also download the installer from https://github.com/shumatech/BOSSA/releases/download/1.9.1/bossa-1.9.1.dmg
Once you have downloaded it, double click on the .dmg file to perform the installation.
On Linux, install from source:
sudo apt install libreadline-dev libwxgtk3.0-gtk3-dev git clone https://github.com/shumatech/BOSSA.git cd BOSSA make sudo cp bin/bossac /usr/local/bin
You can download BOSSA from https://github.com/shumatech/BOSSA/releases/download/1.9.1/bossa-x64-1.9.1.msi
VERY IMPORTANT: During the installation, you must choose to install into
c:\Program Files. The installer might have the wrong path, so edit it to match
After the installation, you must add BOSSA to your PATH:
set PATH=%PATH%;"c:\Program Files\BOSSA";
Test that you have installed “BOSSA” correctly by running this command:
Once you have installed the needed BOSSA command line utility, as in the previous section, you are ready to build and flash code to your Arduino MKR WiFi 1010 board.
Plug your Arduino MKR WiFi 1010 board into your computer’s USB port.
Build and flash your TinyGo code using the
tinygo flashcommand. This command flashes the Arduino MKR WiFi 1010 with the blinky1 example:
tinygo flash -target=arduino-mkrwifi1010 examples/blinky1
The Arduino MKR WiFi 1010 board should restart and then begin running your program.
If you have troubles getting your Arduino MKR WiFi 1010 board to receive code, try this:
Press the “RESET” button on the board two times to get the Arduino MKR WiFi 1010 board ready to receive code.
Now try running the
tinygo flashcommand as above:
tinygo flash -target=arduino-mkrwifi1010 [PATH TO YOUR PROGRAM]
Once you have updated your Arduino MKR WiFi 1010 board the first time, after that you should be able to flash it entirely from the command line.
You can use the USB port to the Arduino MKR WiFi 1010 as a serial port.
UART0 refers to this connection.
For information on how to use the built-in NINA-W102 wireless chip with the default firmware, please see the “wifinina” driver in the TinyGo drivers repository located at https://github.com/tinygo-org/drivers/tree/release/wifinina.
You can also use the Espressif ESP-AT firmware, although you will need to flash it yourself. Please see the “espat” driver in the TinyGo drivers repository located at https://github.com/tinygo-org/drivers/tree/release/espat.
