The ipod ATS certification issue in the i.mx6s

[taehunkim]

Dear Sir,

We are developing our project with the i.mx6 solo.

We have the ipod ATS certification issue.

We could see the error packet of the usb with the usb sniffer when we turn on our board.

When we turn on the our board, the ipod device is connected with our board.

The error log is occurred when we connect the ipod to the otg port.

The normal log(HS port)
