As instructed by website I have downloaded latest NRF52 package for IDE and still Arduino primo core option is not showing on the IDE menu...only primo. Can someone help pls.
Also seeing the same issue. Looks like there is a gap here with the transfer from arduino.org. These are available to purchase, but cannot be used.
As a workaround, you could add the latest version of the arduino.org repo to your own hardware folder in your Arduino directory.
The latest version of the repo: https://github.com/arduino-org/arduino-core-nrf52 (you can download a zip)
Basically, you need to create this path: ../Arduino/hardware/primocore/nrf52/ and put the files from the first link there, then restart the Arduino IDE
In Arduino under the tools/board menu, the primo and primo core will be in the list again
Hope this helps!
