Hi All,

I am evaluating the STM32f4 discovery board. I want to implement the USB mass storage functionality.I interfaced the SD card using the SDIO 1-bit mode.But, I want to share SD card's data in the PC use of USB Mass storage option.

Please help to make it happen.

I need some reference code or document for the same.

Please let me know if you need more information from our side,

Thanks,

Parth Modi

Hi Clive one,

Thanks for quick response.

I check your suggested post.But I find reference code's download link is expired.

So, can you share the working download link for the same?

Thanks,

Hi Parth. The download is working for me. The same URL is reposted here:

https://community.st.com/servlet/JiveServlet/download/43657-1-3309/stm32f4_discovery_msc_sdhc_release_1.zip

Does this download URL work for you ?

Hi Clive one,

Thanks for link.

I tried your suggested example code and i get the USB mass storage drive on the host's PC. But this drive contain the 0 byte space. I used 1-bit sdio interface for interfacing SD CARD.SD card's capacity is 16GB. I am use the IAR as Development tool.

I found this code based on the standard peripheral library. But,I need the USB MSC device sample code with the HAL

library.

Please Share me the working example code with the HAL

library

.

I work for company. So, Can you share the technical support details for the same.?

Thanks,

You'd have to modify code so it doesn't switch to 4-bit mode, and uses the right card detect pin.

I'm not using IAR or HAL, you could try using CubeMX to generate your code.

What technical support details are you seeking? Is your company looking to contract support?
