Hi all,

Does any function for "CYW43907 RMII Loopback test" in the wiced studio?

If no, does anybody know how can I verify the RMII is OK?

Hi,

Sorry for the delay on getting back on this.

I regret to inform you that the RMII pins cannot be set and controlled to GPIO functionality in CYW43907.

To verify the RMII pins, please use the Ethernet. By bringing up the Ethernet, you can probe the pins and verify its operation by referring to the Ethernet Interfacing timing diagrams in CYW43907 data sheet. 

Thanks.

Hi,

Function for RMII Loopback test in CYW43907 is not available in wiced studio.

Instead of RMII, MII loopback test can be performed in wiced.

Thanks.

Hi KotnaniK_71,

Actually, I don't really want to use Ethernet; in my case, I only need to verify these pins(RMII) can be controlled(pull high or low normally) in CYW43907.

That is why I ask you that Can I set these pins to GPIO function and control them?

Thanks.
