AM5726: SDXC Support on Sitara

Hideaki Matsumoto

Part Number: AM5726

Hi,

Do we have any Sitara which supports SDXC of SD I/F ? If we don't have, do we have a plan to support it on future device ?

I know that SDHC is already supported. How about SDXC ?

Thanks and regards,
Hideaki

I found the following post on E2E.

https://e2e.ti.com/support/processors/f/791/p/626893/2312485#2312485

The controller supports SDXC and so does the Linux kernel. What we do not support is the exFAT file system these cards come pre-formatted with. You would need to reformat to ext2/3/4 to use it.

Is there any update from the above ?

Best regards,
Hideaki

Hideaki,

From what I am able to find, the AM57x SDXC status is still the same as you have on your side.

In current AM572x TRM we have:

33.3.7.6.2 SD Cards

33.3.7.6.2.1 System Conditions and Limitations

Even though the ROM Code identities SDXC cards, it does not handle its specificities such as exFAT support. It does neither support UHS-I nor UHS-II speed grades.

Check also below e2e threads, which are newer than the one you have.

Regards,
Pavel
