Hi Trumany,
I try to do eye diagram test according to the “USB 2.0 Test Mode Programming Sequence” in doc.
There is the steps in “USB 2.0 Test Mode Programming Sequence”. And we just do eye diagram test for port 1
step 2.
echo on > /sys/bus/usb/devices/usb1/power/control
echo on > /sys/bus/usb/devices/usb2/power/control

step 3. 
devmem2 0x03610470 w 0xC63

step 4.
devmem2 0x03610020 w 0x804

step 5.
devmem2 0x03610024 
Bus error (core dumped)

Now after I execute step 4, It always trigger "Enter" keyevent and can't stop it, keypad and mouse can't work else.
It occur error(core dumped) when execute step 5.

Please check the problems. 


What board did you do the test on? Is there a USB HUB on board or not?

Hi Trumany,
It’s NX board(jetson-xavier-nx-devkit-emmc) with BOARDID 3668.
Is there a USB HUB on board or not? --Yes

Do you mean NX devkit? Why do you do such test on devkit? It has been validated.
And as there is a USB HUB on that, for any compliance that is going through an external hub, please contact the hub vendor for the tool.
