Help QuadSPI interfacing with MX25R6435F on B-L475E-IOT01A

Aadi__ · ‎2025-01-16

I am developing an audio recording application that captures audio from a MEMS microphone, stores the data in DMA, and saves it as a .wav file using the QuadSPI protocol. I have integrated the FatFS middleware for file system management. While the code compiles without any errors or warnings, my PC fails to recognize the mass storage device when I attempt to read the recorded data.

So the problem is not related to the CubeIDE/Mx nor to the QSPI interface/Flash memory it's more related to the USB usage.

Could you please elaborate more and be concise in your question as the title and the issue description are different?

PS: moved the thread to MCU products and edited the label.

Thank you

Hi @Aadi__

Could you specify where exactly do you see the issue while reading recorded data? Did you try to isolate the issue by simply using USB MSC functionality alone?
