nRF9160 development on MacOS

[pemar13]

Hi

Why is Mac OS no longer listed as a supported operating system for the nRF Connect SDK (see http://developer.nordicsemi.com/nRF_Connect_SDK/doc/0.3.0/nrf/gs_ins_os.html)?

The setup of a MacOS-based development system is described in the latest version v0.9.0 of the Getting Started Assistant in the latest version v2.6.2 of nRF Connect for MacOS.

Following this description it is possible to get development using Segger Embedded Studio for Nordic v 4.16 to work assuming one finds a suitable version of ncs; the recommendation of using tagged releases leaves you with v0.3.0 from December, which, besides being far behind, doesn't work well. I hope a new tagged release is due in the coming days (before the end of the month).

The problem I have is getting the command-line version of development using cmake and ninja to work (runs find under Windows). The command ninja flash gives the error "[Errno 2] No such file or directory: 'nrfjprog': 'nrfjprog'".

I have "installed" the latest version of the nRF5 Command Line Tools (https://www.nordicsemi.com/?sc_itemid=%7B56868165-9553-444D-AA57-15BDE1BF6B49%7D, made sure the path is accessible from the terminal window I run in, and installed the latest version of the J-Link software (https://www.segger.com/downloads/jlink/#J-LinkSoftwareAndDocumentationPack) but this is obviously not sufficient although it is for Windows.

What else should I do?

Best regards,

Hi again!

So I finally got around to try again. In the end, it turns out there was only one thing wrong…

I basically followed the steps in your macOS guide, i.e., preparing for Zephyr, installing the GNU Arm Embedded toolchain, cloning ncs release v0.4.0, “installing” Segger Embedded Studio ARM v416 Nordic, and installing JLink_MacOSX_V644i.

At this stage building and programming using Segger Embedded Studio works fine.

After “installing” nRF-Command-Line-Tools_9_8_1_OSX and setting up a permanent path for bash to the folders nrfjprog, ninja flash fails as before whereas running nrfjprog -v results in the expected lines: ‘nrfjprog version: 9.8.1’ and ‘JLinkARM.dll version: 6.44i’.

The reason for this must be that ninja doesn’t know the path to nrfjprog. Indeed, manual programming using ‘nrfjprog --program …/build/zephyr/zephyr.hex -f NRF91 --sectorerase' works fine.

To solve the path issue, I created a symlink to nrfjprog in /usr/local/bin by executing ‘ln -s /path/to/nrfjprog/nrfjprog /usr/local/bin/nrfjprog’.

Now things work.

Best regards,
