How do I program the Arduino Primo Core using the Arduino Primo?

Question

the Arduino Primo Core website (https://store.arduino.cc/usa/arduino-primo-core) says that I can program the Arduino Primo Core using an Arduino Primo.

I have no idea how to do this!

Can you do it through the Arduino IDE? Which pins on the Arduino Primo Core should I connect to which pins on the Arduino Primo?

Thanks for your help!

Answer 2

Juraj's answer answered my question, however I've gone back since and found the link to be broken. Fortunately I saved the file so I'll summarise here for others:

1. Download the nRF52 platform using the Boards Manager:

2. Connect the Arduino Primo Core to the Arduino Primo using a SWD connector (J2 on Arduino Primo Core and J9 on the Arduino Primo):

3. Plug the Arduino Primo into the PC using a USB data cable.

4. Select "Arduino Primo Core" from the Tools > Board menu:

5. Select the corresponding port of the Arduino Primo from the Tools > Port menu:

6. Select the Blink sketch from the File > Examples > 1. Basics menu.

7. Upload the sketch. If the light blinks on the Arduino Primo Core it has worked!
