SD Card no file system error.

Hi,

I would like to make an application to access micro sd card via SPI from STM32F407VG-DISC1 board. I have configured the pins as seen in table below.

Main file is also attached. 

However, when I run the application I get FR_NO_FILESYSTEM error. My card is formatted as FAT32. It is class4 2GB micro SD card. 

When I remove the SD card then I received another error that is FR_NOT_READY. So, this got me thinking that, I have made proper connections, but there is problem with the code.

Could you please point me to the right direction ?

You have to un-mark one before you can mark a different one
