Hi friends, looking for any project based on STM32F105 which can copy (Transfer) files from USB stick to On board SD card repeatedly. May be such a device can be used to batch copy files from USB stick to SD card without any Computer.

Probably wouldn't do it with the F105, given the choice.

The STM32F4-DISCO has code examples for USB-MSC reader, there's SDIO code, and FATFS implementation. To clone/copy a card you'd need to write some code to enumerate the files/sub-directories and copy/create them one at a time between the media.

Hi clive1,

why not STM32F105 as it USB FS Core and Native SDIO interface with DMA Support.

You can build your project with whatever part you want.

I think there are other parts, which are faster, have more memory, and more available/working code.

Ok, i will try to implement the concept with STM32F105 (Cheapest one with USB FS host & SDIO).
