Hi,

Request to please point to the link and example code for accesing the file system for externaly connected memory drive like memory card,micro sd card , usb pen drive or any ST specific component/evaluation board/shield.

Thanks in advance ,

Which Nucleo board, they make at least 3 variants (32, 64, 144) across several models of STM32 part.

I've used MicroSD cards via SPI on a shield like

.

I've work with other people who have removed the L15x part and replaced it with another supporting SDIO connectivity.

The Nucleo144 seems to provide pins to support SDIO.

I've posted MSC and FATFS examples for the STM32F4-DISCO that might be portable, and there are SDIO examples as part of the F4 SPL packages.

I think there should be a couple of SPI MMC/SD card examples around, which should be portable.

It is STM32F4 Nucleo Board.Can you please point to the STM32F4-DISCO example and h/w connections figure.I will try to port it to STM32F4.

Thanks in advance ,

There are at least two different STM32F4 nucleos.....
