The Micro:Bit is a very small ARM Cortex-M0 board designed by the BBC for computer education. It's fitted with a Nordic nRF51 Bluetooth enabled microcontroller and an embedded programmer. You can get it at:
How to setup the Ada development environment for the Micro:Bit
GNAT Community now comes with micro:bit and pyOCD support built-in. So you only need to download the ARM ELF and the native package from here
The Micro:Bit comes with an embedded programming/debugging probe implementing the CMSIS-DAP protocol defined by ARM.
To use it on Linux, you might need privileges to access the USB ports without which the flash program will say "No connected boards".
To do this on Ubuntu, you can do it by creating (as administrator) the file /etc/udev/rules.d/mbed.rules and add the line:
then restarting the service by doing
$ sudo udevadm trigger
Open one of example projects and build it
Start GNAT Programming studio (GPS) and open the micro:bit example project:
Press F4 and then press Enter to build the project.
Program the board
Plug your micro:bit board with a USB cable, and wait for the system to recognize it. This can take a few seconds
In the GPS toolbar, click on the "flash to board" button to program the micro:bit.
After a few seconds, you should see a text scrolling on the LED matrix.
That's it, you are ready to hack the micro:bit with Ada!
