I am using AM3354 with eMMC (Micron 4 GB) connected on MMC1.

I am able to read and write single sectors(block) also multiple continous sectors (for eg. from 20 to 40).

But once i write single block after that i am not able to write on other sector. For eg. i write something on sector 0 (successfully written) then on sector 20 not able to write.

I am following beagle bone black schematic and Starterware 02_00_01_01.

Actually i want to create FATFS on eMMC1.

Kindly help.

fdisk + mkfs dont’t work?

then what is the solution. How can i create FAT FS on emmc using Elm Chan code.
