Hi,

   I use MCIMX6L2EVN10AB of my own board, when I use the USB port configered as USB1.1, and I found that the eye diagram is bad. I want to know which registers can be used to strengthen the drive capability of USB? I know some other cortex A9 cpu has registers to configer the usb drive capability, but I don't know if IMX6SL has or not.

  (By the way,  I know there is hardware solution to improve the eye diagram, but firstly I want to know if there is software solution.) Thank you!
