there are no peripherals descriptions available, install required packs

[Peter]

Developing an application on nRF52 DK board using Eclipse Neon.3 (4.6.3). When the program is run the following message is displayed in red across the bottom: There are no peripherals descriptions available, install the required packs.

Tried the solution on this page. No joy. Help please. devzone.nordicsemi.com/.../

What SDK version are you using? Did you try to restart Eclipse after you applied the changes?

[Peter]

Using nRF5 SDK v12.1.0. Yes, restarted eclipse after the changes - in eclipse menu, File / Restart. What does that tell you? Can you explain what this error means?

[Sigurd]

How does your device settings look like? Have you selected the correct device?

See picture:

Cheers. That looks like the problemo. In the above screen under Devices tab it says "No devices available, install packs first". Trying to install this eclipse says plugin GNU ARM Eclipse 3.4.1 is installed. The installed plugins list includes "GNU ARM C/C++ Packs (Experimental)". What do I need to install?

[Sigurd]

According to the tutorial, you should install the following packages:

• GNU ARM C/C++ Cross Compiler
• GNU ARM C/C++ Packs
• GNU ARM C/C++ J-link Debugging

Please make sure that you have installed them.

I also recommend installing the nRF5x Command Line Tools. Find the installer for your OS in the list here, under "PC software".
