i'm having issue with reading SD card on STM32F746,
i need to read file with size 1.5GB from SD card using SDIO with FatFS library,
i used CubeMX for clock calculations :
external HSE crystal 12MHz
PLL: M: /6, N: x216, P: /2, Q: /9,
CLK48 = 48MHz, HCLK = 216MHz, SDMMC clk switched to PLL48CLK = 48MHz
everytime when try to read same file , i got disk io errors from SDIO controller, it happens randomly after 2MB - 3MBytes ... without DMA,
please anybody could help me to solve my issue ?
when i use SD card in card reader - file is read continuously until the end correctly ...
EDIT: same testcase went successful on STM32F417 ... but on F7 failed :-(
error got from HAL in SDMMC_STA register : RXOVERR ... but i don't use DMA :-(
