SDIO partial block DMA transfer possible?

Hi,

I'd like to transfer less than a full block of data (i.e. less than 512 bytes) from the SDIO FIFO to another peripheral that's mapped into an FSMC address directly using DMA without having to first transfer the full block to SRAM then again out to the FSMC address.

Is that possible? The SDIO spec hints at partial block transfers being possible but I don't see the capability in ST's driver code.

Regards,
- Andy
