stm32n6 using cubeai to train its model; compilation fails: `.rodata' will not fit in region `ROM'

[LQC_]

Hello
I trained handwritten digits using Keras, and then used cubeai of cubeMX to train and deploy, and then there was an error when compiling. Do you know how to solve it?

Hello @LQC_,

 

I would suggest you using the ST Model Zoo to deploy your model.

You can follow this tutorial: https://github.com/STMicroelectronics/stm32ai-modelzoo-services/blob/main/image_classification/deployment/README_STM32N6.md

 

You will be able to see the source code of the application deployed in the folder /application_code/image_classification/stm32n6

 

Have a good day,

Julian

Hello, I use st-minst in ST Model Zoo to deploy my project, but when I burned stm32N6570_DK, it didn't work. However, I tried flower and food and they both worked fine. Why can't st-minst work? Are there other steps required?
This is my command and .yaml content
