STM32N6570 and storing a model in the flash

[llcc]

Hello! How can I store the model's input data in the flash of the STM32N6570-DK, then deploy the model, read the input data from flash, and perform inference? Are there any relevant tutorials for this? I previously followed the model deployment tutorial in the link below. Can this deployment method support reading input_data directly from flash? If not, are there alternative approaches to achieve this goal? Thanks.

Hello @llcc,

We don't currently have any tutorial for that.

We should deliver in the coming days a tutorial about creating a X Cube AI appli to do an ai inference and a FSBL loading this appli from external flash to internal ram. I will update you once we have it available.

Have a good day,

Julian

Hello, I am currently trying to write my input_data_int8.bin file to flash, but I keep getting an error that says 'Error: failed to download the file'. How can I fix this? Thanks!

Hello @llcc,

did you select the external loader for the DK board?

Yes, I have. I've now identified the issue. It was caused by an incorrect Start Address setting. Changing it to 0x70000000 resolved the problem.
