nRF5340 Compiler and IDE

Frikkie Badenhorst

Hi there,

We are currently using IAR embedded workbecnh IDE for our development on non-Nordic products. We are thus considering the possibility of also porting our Nordic projects to IAR, since we are experienced in IAR and the IAR compiler is also a lot better than GCC.

We are currently using the VS Code extension to develop. Which compiler is used out of the box with VS Code? Is the firmware written to support the IAR compiler? Do you perhaps have any information on porting projects to IAR? Are there any plans to implement IAR support in future "out of the box"?

I look forward to hearing from you.

Regards,

Frikkie

    Hi Frikkie,

    The IAR compiler is currently not supported by Zephyr nor our nRF Connect SDK, unfortunately.  The SDK uses the GCC toolchain and adding support for IAR will require changes to both the code base and the build system. I'm also not sure if IAR offers any integration with Cmake. Either way, I think the VS code is going to be better as an IDE with its cmake, devicetree and kconfig integration. Having other compilers to choose from would have been nice though. I will add this as a feature request.

    Regards,
