I think stlink doesn't initialize itself in the nucleo-f767zi

[YoungKim]

I have a nucleo-f767zi. When I connect it to my Linux computer by USB cable, LD4 keeps blinking red slowly and LD6 goes to solid green. And it stays there forever. I checked in the document LD4 should go to blinking red quickly then solid red. Can you help me?

I am sorry. The usb cable was only for power.

It works after I change the cable for both data and power.
