SdBusSubmitRequest CMD52 CMD53 wrong

The SD bus need transmit block one by one.
I do not know what is the block size of each?
and what different between SDTT_SINGLE_BLOCK and SDTT_MULTI_BLOCK?


How to send the image file down to the HW?
Idefine a function as below, but the return of the sdrp->ResponseData is
1000h
and the sdrp->ResponseLength is 4 all the time.

why?
Who knows difference in Response1 to Response5?
