Tool/software:

Hi, Dear Expert

As title description, What is SDIO Spec? 

Does it SDIO 3.0 or SDIO 4.0?

Because I saw something different.

In TRM,

Which spec is correct one?

Thank You.

    Hi Gibbs,

    Thanks for catching this. The correct specs for DRA821U is SD3.0/SDIO3.0. The datasheet has the correct information here.

    The TRM is mistaken here, and we will plan to change this in the next revision of the TRM.

    Best Regards,

    Matt
