Hello, did you happen to solve the issue on this matter? im obtaining the same error on the same version of Segger Embedded, I would like to make this project work for this particular new version of segger

[giopoli2000]

But if you want the easy fix, just download the Segger Embedded version 5.70a and you will not find the same linker problems you are having now

Hello, @giopoli2000 . I could not solve the problem. Also 'solved' by downloading an old version (as you sugested) of Segger Embedded and it is now working.

It would be great if this project could be upgraded for the new version of Segger Embedded!

Thank you for the reply!

Hi all, I had this problem too with the latest SES (6.30) version, after a bit of searching I found this post on the Nordic forums that helped solve it: https://devzone.nordicsemi.com/f/nordic-q-a/86110/nrf5-sdk-17-1-0-examples-is-not-compiling-in-latest-ses-6-20a Cheers, Matt
