Help QuadSPI interfacing with MX25R6435F on B-L475E-IOT01A

[Aadi__]

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

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?
