PROCESSOR-SDK-J7200: Support USB3.1 Super-speed with PSDK-J7200-Linux

Jack

Part Number: PROCESSOR-SDK-J7200
Other Parts Discussed in Thread: J7200XSOMXEVM, J721EXCPXEVM

Hi TI

Can you please check if USB3.1 can be supported by PSDK-J7200-LINUX?

A customer reported Type-C port does not work for USB3.1 as mentioned in SDK document as below.

According to google search, J7200 SDK seems that it configured USB module to USB2.0 only mode due to SerDes restriction.

Can you please confirm if USB3.1 can be tested in EVM Kit? and How to modify DT and other relevant code?

They did try to follow the J721e' DT file, But it still work only for USB2.0 high speed mode.

Please provide us with the necessary changes to activate USB 3.1 mode via Type-C port.

The following snapshot is captured while USB3 capable device is inserted

We need your prompt response.

Thanks.

Regards,

Jack
