nRF52 Toolchain Setup in Mac OS X

Readme.md

Equipment

• MacOS Mojave 10.14.4
• MacBook Pro (Retina, 13-inch, Late 2012)
• nRF52-DK (PCA10040)

Toolchain Setup

1. Install GCC

brew tap PX4/homebrew-px4
brew update
brew install gcc-arm-none-eabi

2. Download and unzip inside ~/Development/nRF52/

• nRF5-SDK 15.3.0 in SDK_15.3.0 folder
• nRF5 Command Line Tools 9.8.1 in CLT_9.8.1 folder

3. Symlink command line tools

ln -s ~/Development/nRF52/CLT_9.8.1/nrfjprog/nrfjprog /usr/local/bin/nrfjprog
ln -s ~/Development/nRF52/CLT_9.8.1/mergehex/mergehex /usr/local/bin/mergehex

4. Change the nRF SDK to use my version of arm-gcc changing the file ~/Development/nRF52/SDK_15.3.0/components/toolchain/gcc/Makefile.posix to reflect the location of my homebrew installed version

GNU_INSTALL_ROOT := /usr/local/Cellar/gcc-arm-none-eabi/20180627/bin
GNU_VERSION := 7.3.1
GNU_PREFIX := arm-none-eabi

5. Install J-Link Software and Documentation pack for MacOSX 6.44e

Testing

cd ~/Development/nRF52/SDK_15.3.0/examples/peripheral/blinky/pca10040/blank/armgcc
make
make flash

I just made a concise version of Aaron Eiche's Programming an nRF52 on a Mac

Hi, I'm trying to use LTE Link Monitor to send some AT Commands to my test on Thingy:91 and Thingy:52. I've connect the device using a good USB cable, but I'm getting the following messages in the log window:

15:03:08.445 Application data folder: /Users/angelo/Library/Application Support/nrfconnect/pc-nrfconnect-linkmonitor
15:03:08.619 Error while probing devices: Error occured when get serial numbers. Errorcode: CouldNotOpenDLL (0x7) Lowlevel error: JLINKARM_DLL_NOT_FOUND (ffffff9c)

In the menu there is a "no devices available" .

What am I missing?

Regards
