HI,

I'm trying use SDIO interface on STM32F469I-Discovery board ​and I'm always getting FR_DISK_ERR for the command "f_open(&myfile,myPath,FA_CREATE_ALWAYS|FA_WRITE)" Same problem is observed  with 1-bit and 4-bit SDIO mode. I have enabled "Use DMA template" and using FAT32 formatted 16GB Micro SD card with a sector size of 4096 bytes. And also I have enabled SDIO Global interrupt. What is the maximum size of Micro SD card supported by the STM32F469I-Discovery board?Can anyone help me in resolving the issue?

Thanks in advance

Sunil
