I use RT1061 to configure SD Card, SD Card is mounted successfully.
Have you checked the examples we have available in our MCUXpresso SDK?
sdcard_fatfs example mounts a file system based on a SD card and then does "creat directory/read directory/create file/write file/read file" operation.
You can download the SDK in this link: https://mcuxpresso.nxp.com/en/welcome
