Keil and IAR dual core configure and debug for MCXN 947

Hi NXP,

I can't find the application note about dual core configure and debug for MCXN947 in Keil and IAR.

Hope you help to provide this documents to help us .

Thanks very much.

Hello @jimmyli ,

Sorry, we don't have AN for dual‑core configuration and debugging of MCXN947 in Keil or IAR.

However, NXP provides several official resources that can help you set up, configure, and debug dual‑core MCXN947 projects in Keil and IAR:

1. NXP’s MCUXpresso SDK includes IAR project examples (such as hello_world, TrustZone, etc.) that demonstrate how to build and debug applications on MCXN9xx platforms.
These examples show the correct project structure, build settings, and debug steps for IAR Embedded Workbench.

Run a demo application using IAR — MCUXpresso SDK Documentation

2. Dual‑core Reference Code on GitHub
NXP provides open-source dual-core communication examples for MCXN947 on GitHub.
These repositories include both core0 and core1 configurations and compiler support for IAR and Keil, useful as a reference for setting up dual‑core projects.

dm-dual-core-i2c-communication-on-mcxn947/dm_dual_core_i2c_MASTER/device/system_MCXN947_cm33_core0.h at main · nxp-appcodehub/dm-dual-core-i2c-communication-on-mcxn947 · GitHub

You can also obtain the SDK zip package for Keil/IAR from the SDK Builder. It includes many dual‑core examples for customer reference.

For instructions on how to use the SDK Builder and how to import the demo projects into IAR/KEIL, please refer to the following documentation.

SDK Builder — MCUXpresso SDK Documentation

Hope it helps.

Hi Celeste,

Get it.

Thanks very much.

BTW, I hope there can be some documents to describe about developing dual core projects in Keil and IAR, which can show the details of project configuration, how to compile, how to debug, how to generate and download the combined bin, and so on. This is very useful for customers to understand and develop their project by mcxn947.

Thanks again.

Hello @jimmyli ,

Thank you for your suggestion. I will pass it on to our internal team, and we will consider publishing such documentation.
