RTOS/AM5728: Mounting multiple partitions with FatFS

Tool/software: TI-RTOS

Dear friends,

I am using Sitara AM5728 IDK and standard uSD card with 2 FAT32 partitions configured and recognized by windows.

I am trying to "mount" the second partition from RTOS FatFS.

My starting point was the MMCSD_FatfsConsole_idkAM572x_DMA_armExampleProject, in which I changed the default volume to 1 instead of 0.

Unfortunately, it seems like FatFs only recognizes the first partition.

I tried to format the second partition as primary and logical, but this does not help.

Your help is very appreciated.

Thanks,

Avi Tal.

Hi,

I had a similar testing with a SD card. By using some utility I created several partitions and was able to see it in a Windows 10 machine. I tried FATFS_Console_idkAM572x_armExampleProject on AM572x IDK EVM to mount the second partition, I had some code changes for this purpose. But it looked that I was only able to mount the first partition. We are looking at it and will update once we succeed.

Regards, Eric

Hi,

This is exactly what I did.

It seems like FatFs needs upgrade so it is able to recognize multiple partitions.

Looking forward to your update.

Thanks,

Avi Tal.
