How to test USB2514i (hub) eye diagram in imx6Q

[zohanlin]

Dear all,

I want to test the USB2514i eye diagram in imx6Q, and it is connected to USB HOST.

I use the command as below :

memtool -32 0x020c4080=0x3

memtool -32 0x02184340=0x2
memtool -32 0x02184384=0x1C040000

I can detect the signal between CPU and HUB, but I can't detect anything between HUB and miniPCIe.

Could anyone tell me how to solve the problem?

Thanks,

zohan
