reading SD card on STM32F7

Hi there,

 

is there anybody with STM32F7XX and is able to read bigger file (larger than 30MBytes) from SD card until the end ? without DMA ?

i'm asking because i tried more types of cards, and i tried to setup clk div for SDIO to 400kHz and i don't have any success :-(

i always get error RXOVERR in SDMMC_STA after couple MBytes (2MB-3MB)

 

i need just confirmation that it's possible ...

 

thanks for all replies ...

 

Kind regards
