Documentation for the machine package for the Arduino Zero
In order to flash your TinyGo programs onto the Arduino Zero 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 cask 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-*
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 much choose to install into c:\Program Files
. The installer might have the wrong path, so edit it to match c:\Program Files
.
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:
bossac --help
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 Zero board.
Build and flash your TinyGo code using the tinygo flash
command. This command flashes the Arduino Zero with the blinky1 example:
tinygo flash -target=arduino-zero examples/blinky1
The Arduino Zero board should restart and then begin running your program.
If you have troubles getting your Arduino Zero board to receive code, try this:
Now try running the tinygo flash
command as above:
tinygo flash -target=arduino-zero [PATH TO YOUR PROGRAM]
Once you have updated your Arduino Zero 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 Zero as a serial port. UART0
refers to this connection.
