Used Ram over External SDRAM and TFlite Micro runtime

[pepsi_zero_sugar]

It seems like a used ram size fit to External SDRAM in STM32H757i- EVAL Board.
However, I can see the error when doing analyze.

Also, I cannot see any TFLite Micro runtime generated code.
I can see empty function.
I was totally fine with STM32CUBE AI runtime.

You have to select the Template code, System performance application or Validation application to have code generated in those sections

I selected the Validation application.

I was wondering if TFlite model Used Ram: 1.29MiB, then MCU need x10 size RAM?
It is showing that 1.29 MiB. However, 8 MiB External SDRAM is not enough.

with tflite runtime we don't manage automatically the use of external RAM.

That said you can generate the code and modify the linker script to place the activation buffer in external sdram (with of course an impact on the performance)
