My problem just like https://community.st.com/s/question/0D50X00009XkdhZ/sdfindscr-function-problem

In ​the SD_init function ,I use HAL_SD_ConfigWideBusOperation to change bus wide.

but sometime it will dead in SD_FindSCR => while(!__HAL_SD_GET_FLAG(hsd, SDMMC_FLAG_RXOVERR | SDMMC_FLAG_DCRCFAIL | SDMMC_FLAG_DTIMEOUT | SDMMC_FLAG_DBCKEND))

I use Stm32F746 , HAL Library F7 v1.16

My SD hardware have Pull-up resistor(47k),can anyone give directions?

My English is not very well,If there's anything you haven't understood, please say so.

Thanks!!
