SDIO transfer speed

Prodigy 10 points

Hi All,

I want to know the time required in nano seconds for transferring 256 bytes of data to SDIO card on DM368 platform running 2.6.32 kernel at 432Mhz. SDIO clock is at 50Mhz.

Platform: DM368

OS: Linux 2.6.32

CPU Freq: 432Mhz

SDIO clock: 50 Mhz

Memory: 128Mb

What will be the latency to transfer 256bytes of data through SDIO interface ?

Thanks,

Satish.
