What is maximum tflite model size that can be deployed on MCXN947?

I am newbie with NXP board. I have a board MCXN947 and I read the specification of this board. It mentioned 3 Flash: 2MB with ECC, 64 Mbit fro QSPI flash and 512 Mbit Octal flash. So when deploy tflite model on this board, which flash memory I will flash into? I am concern about this problem because may be I can not deploy a "large" model. I am using MCUXpresso and examples from SDK + Code Hub.

I surprised about small flash memory of this board compared to MIMXRT1xxx boards.

Hi @nnxxpp

When deploy tflite model on this board, you will flash into 2MB Flash.

Hi @Harry_Zhang

2 MB is very small. If my model size is larger than 2 MB. I don't want to reduce model size. What I need to do ? Can I use other flashes or external storage to run model? Thanks.
