USB3.0 test pattern on 66AK2Hxx

Hi, 

Would you like generate test pattern from Linux or Windows?

How the EVMs USB port is used? 

Please provide the your test setup diagram. We will work with team and get back to you.

Thank you.

Hi Rajasekaran,

Thanks for your reply.

Either the Linux or Windows were all ok for me. I only had experience on Linux to test USB2.0.

Let me show you my test steps in another TI's platform.

(1) High Speed

      # mount -t debugfs none /sys/kernel/debug/

      # echo "force high-speed" > /sys/kernel/debug/musb/testmode

      # echo "F" > /proc/driver/musb_hdrc.0

      # echo "T" > /proc/driver/musb_hdrc.0

(2) TEST J

      # mount -t debugfs none /sys/kernel/debug/

      # echo "test J" > /sys/kernel/debug/musb/testmode

(3) TEST K

      # mount -t debugfs none /sys/kernel/debug/

      # echo "test K" > /sys/kernel/debug/musb/testmode

Hi OC,

Looks like test mode support only available for USB2.0. Please refer the USB 3.0 User guide(SPRUHJ7), Section 3.2.3.5 PORTPMSC2 for more information.

Thank you.

Hi Rajasekaran,

I checked user guide that did not explain enough to help us to test eye diagram on USB3.0 port.

Could you kindly help to indicate a appropriate method for USB3.0 eye diagram test?

Thanks in advance.
