How to compile sample project from SDK for nRF52 successfully after importing it to IAR workbench

[Avinash]

Right now I am facing a problem as mentioned below: I downloaded nRF52 SDK version 12.3.0. It contains lot of example code. I found .eww file in each example project folder. I was able to open the project by double clicking on the .eww file. In IAR IDE, under workspace, it lists down the project name and associated files. It lists all the included header files as well. However, the problem arises when I try to compile the project. It gives lot of errors which are kind of dependency errors. I am not sure, how to readily use the given example code, compile them and run it on target board. Following are some of the errors that I see on compiling any of the example project:

Hi,

It looks that you are using not supported IAR version. If possible please downgrade to: IAR Workbench 7.60.2.

[Avinash]

I am using IAR workbench 8.11.2. I am not sure how downgrading IAR version will solve the problem. May I know, how you identified that it is could be IAR version mismatch issue?

[Jakub Rzeszutko]

Please refer to this topic: devzone.nordicsemi.com/.../

[Avinash]

Thanks for the explanation. But, I am unable to find older versions of IAR workbench to download. Is it possible for you to provide me link to download IAR v 7.60.2?

[Jakub Rzeszutko]

I would recommend to contact IAR directly.
