Hi,
I have interfaced SD card to MCU. I can read and write to the sd card. But I want to read and write to the SD in FAT32 format.
Cheers

Hi,
I have sent you a function set that can help you to implement FAT32/FAT16 in your Project.
You should review all the functions and modify it to adapt with your design.
Enjoy it.

Hi,

I have created a file and when I read the boot sector data, the file name should be in the boot sector (512 bytes) right? Boot sector shows that it is FAT32 and many more info.
Is there any other command to be initialised before getbootsector?
Cheers

Hello!

No, the name of the file you have created is not (or at least should not be)
in the boot sector.
The file name might be in the root sector (which is not the boot sector), or in
another sector in case your file is in a folder.
