Replaced model does not work ML NPU for MCN947

Hello, I need your assistance.

I exactly followed your tutorial:

https://community.nxp.com/t5/MCX-Microcontrollers-Knowledge/MCXN947-How-to-Train-and-Deploy-Customer-ML-model-to-NPU/ta-p/1899497?lightbox-message-images-1899497=287107i2978774ED40465C2

I once used the sample project: dm-label-cifar10-images-on-mcxn947-main and dm-fashion-mnist-recognition-on-mcxn947 but both with same problem.

I have trained a very simple model, see in the attachment and I tested them on PC webcam which works perfectly. Then I convert it to FRDM-MCXN947 but then it seems the normalization isnt correct. The result always show something wrong. I am using the Neutron converter version MCUXpresso SDK2.14.0 because going higher it says the version does not match. Could you assist me? Thanks!

best regards

Sherlock

thanks for your quick reply. So I have tested with MCUXpresso SDK 2.16 and 2.15.004 which says the version does not match. With version 2.14.0 I was able to use the model but the image classification isnt detecting correctly. I will also try 2.13.1
