FREERTOS + USB Device (Mass Storage Class) + SDcard (SPI Interface) - Is it possible?

Hi All,

Is it possible to have a FREERTOS system with a SPI SD card interface that appears to the PC as a Mass Storage Device?

The STM32 will write information to the card and the PC is required to copy it off the card for the USB interface.

If so, any links on how to achieve this.

Thanks.

You can use STM32 as a USB card reader. FreeRTOS makes no difference to achieve this. example:
