Other Parts Discussed in Thread: AM3351

We are testing broadcom wifi BCM43455 on our custom board based on AM3351, where the Wifi chip supports SDIO 3.0. Will AM3351 supports SDIO 3.0 version..? I'm currently using processor-sdk-02.00.02.11.

Please read section 18.1.1 from the AM335x TRM Rev. N.

It says "SDIO command/response sets and interrupt/read-wait suspend-resume operations as defined in
the SD part E1 specification v 2.00". Does it mean that it will not support SDIO3.0

I don't have access to the SDIO specifications, but generally they are created with backward compatibility.
