ATA File System Known Working SD Cards

Other Parts Discussed in Thread: TMS320C5515

Hi,

We're using the ATA File System Library from TI in a TMS320C5515 to interact with a SD card on our board.

I have some generic micro SD cards I'm using on my development board and they are working with no issue.

The other day I tried a brand new 2GB from SanDisk and I'm having issues trying to create files with the ATA File System, the method

ATA_create() consistently fails.

To make sure that it wasn't the physical SD card, I did verify that a PC can properly interact with the SanDisk micro SD card.

Does anyone know of a known list of working SD cards and the ATA File System?

Or, is there a way to know if a card will function properly with the ATA File System without having to test it first?

Thanks,

Ben

    C5515 is developed to use with SD devices that comply with SD Specifications Part 1 Physical Layer Simplified Specification v1.1 or v2.0 and formatted in FAT16/32. We tested with a large numbers of market available SD and MMC cards at that time. Spec compliance is what I would use to idenify working cards.
