How to use SD card for storage ML model?

[nnxxpp]

My board is MCXN947 but internal flash is 2 MB. It is small for my tflite model. I know that MCXN947 supports SD card. How can I use SD card to save and run my model? I want to the flow is same before. Before I use the internal flash and debug via USB.

Thank you.

Thanks.

So in my case the external flash maybe is the best solution. How do you think about it? Please give me some advice and tutorials.

Hi @nnxxpp 

I think you can use external flash to store your code and XIP.

So you can refer to hello_world_qspi_xip example.

Hi @nnxxpp 

If you want to save your model in SD card, this is possible.

You can refer to this example.

But MCXN947 doesn't support booting from SD card.
