Adafruit nRF52 BSP via git (for core development and PRs only)

1. Install BSP via Board Manager as above to install compiler & tools.

2. Delete the core folder nrf52 installed by Board Manager in Adruino15, depending on your OS. It could be

OS X: ~/Library/Arduino15/packages/adafruit/hardware/nrf52

Linux: ~/.arduino15/packages/adafruit/hardware/nrf52

Windows: %APPDATA%\Local\Arduino15\packages\adafruit\hardware\nrf52

3. Go to the sketchbook folder on your command line, which should be one of the following:

OS X: ~/Documents/Arduino

Linux: ~/Arduino

Windows: ~/Documents/Arduino

4. Create a folder named hardware/Adafruit , if it does not exist, and change directories into it.

5. Clone the Adafruit_nRF52_Arduino (https://adafru.it/vaF) repo in the folder described in step 2:

git clone git@github.com:adafruit/Adafruit_nRF52_Arduino.git

6. This should result in a final folder name like ' ~/Documents/Arduino/hardware/Adafruit/Adafruit_nRF52_Arduino ' (OS X).

7. Restart the Arduino IDE

BSP FAQs

The following FAQs may be useful if you run into any problems:

I cannot upload sketch to Feather nRF52 !! Although I have followed the tutorial correctly.

This is probably caused by the bootloader version mismatched on your feather and installed BSP. Due to the

difference in flash layout (more details) and Softdevice API (which is bundled with bootloader), sketch built with

selected bootloader can only upload to board having the same version. In short, you need to upgrade/burn

bootloader that come with the BSP using this guide

On Linux I'm getting 'arm-none-eabi-g++: no such file or directory', even though 'arm-none-eabi-g++' exists in the

path specified. What should I do?

This is probably caused by a conflict between 32-bit and 64-bit versions of the compiler, libc and the IDE. The

compiler uses 32-bit binaries, so you also need to have a 32-bit version of libc installed on your system (details). Try

running the following commands from the command line to resolve this:

sudo dpkg --add-architecture i386

sudo apt-get update

sudo apt-get install libc6:i386
