MCXN947 compatible eIQ Neutron SDK

cllmrrkn — Mon, 23 Feb 2026 10:04:05 GMT

Hello,

I am trying to develop an object detection model on MCXN947, and I took the Multiple Face Detection example code as basis. However, when I put my own model into the files, I get the error "Incompatible Neutron NPU microcode and driver versions!". My SDK version is 25.09.00. Could you please tell me which eIQ Toolkit or eIQ Neutron SDK I should use to do my conversion?

Thanks

Hi,

Follow the attached lab guide here for how to update the MCX N Face Detect example for this exact issue. It will require replacing the "eIQ" folder in that ACH example with the newer "eIQ" code from MCUXpresso SDK, and then updating the Neutron libraries from the latest eIQ Neutron SDK: https://community.nxp.com/t5/MCX-Microcontrollers-Knowledge/Using-a-Camera-with-FRDM-MCXN947-for-Vision-AI-ML/ta-p/2313227

I'd recommend doing the MCX N NPU labs first though to understand the eIQ Neutron SDK and then do that Face Detect lab second.
