STM32F4 + USB MSD + SDIO Working Example

[voyvoda .]

Hello,

I am using STM32Cube_FW_F4_V1.21.0 library version.

I would like to implement USB mass storage device example along with SDIO interface. When I connect my STM32 device with the PC, I wish to see my SD card content on my PC.

I made some configuration in the cubemx. However it is not working.

Could someone share a working copy ?

Do I need to modify the content of the "usbd_storage_if.c" file ?

When I compile and download the code. I see a USB problem.

What could be the possible solution ?

Have you ported it to your specific board? STM32F4 is overly broad, perhaps you can be more precise about the board in question.

Clocks, pins, HSE frequency and PLL settings? HSE_VALUE?

Thanks Clive,

it is PLL Settings. Now it is working
