RE: Working with nRF connect SDK 2.7.0 on IAR Embedded Workbench

I also wanted to build under the old SDK for low-level peripheral testing, but this is less than simple. IAR can be run as both compiler and IDE under Visual Code, but that was just too much work. These files from nRFConnect v2.7.0 need to be copied into this directory for the blinky peripheral example to get you started if wanting to build under the old SDK. Note this is not a simple task to work under the old SDK.

This is an example of the .icf link file:

devzone.nordicsemi.com/.../blinky_5F00_pca10156.icf

This is an example project; note that using secure or non-secure is a major headache (nRFConnect SDK makes this easier):

devzone.nordicsemi.com/.../blinky_5F00_pca10156.ewp.txt

Edit: If using a version of IAR which doesn't know about nRF54L15 use nrfjprog to download the hex and then "debug without downloading":

Hi Ruthrapathy,

This is mentioned in the documentation for nRF Connect SDK : nRF Connect SDK is IDE agnostic, which means you can use your own IDE if you prefer.

You can use IAR as the IDE, however you would need to use west build systems to build the application.
As for the question why IAR is not supported, we have to focus on one single build system and it's the same system to build Zephyr RTOS.
The recommended IDE to be used with NRF Connect is Visual Studio Code. Different from the past with nRF5 SDK that we relied on 3rd party IDEs to support us in developing the IDE and compiler, with VSCode we have a team in Nordic that working on it to build our own build system and integrated in VSCode as the nRF Connect extension.
