I'm trying to run `fatfs_sdcard` example from LPC54628 SDK. I\m running the example without any modyfications. When debugging mounting (f_mount) and selecting drive (f_chdrive) works fine. But when creating directory the program exits, beacuse the function returns code `FR_NOT_READY`. I have read some information and people say that maybe it's low level problem. I'm using 8GB KINGSTON class 4 SD card with adapter. It's the problem with the card? Maybe I have to format it properly? Now it's formatted using Windows as FAT32 module with default allocation unit. Maybe have I change something in the project?
