Trouble measuring eye pattern on Colibri iMX8X

Hi team,
a customer is trying to measure the eye pattern from the USB host on a Colibri iMX8X (they are using their own custom carrier board), but he doesn’t seem to get any results.

Is there any application that can be used or setting which needs to be enabled in order to visualize this? What would be the best way to measure it or get the desired results?

Thank you!

Hi @jorge.tx , please check this post from NXP:

Kindly use the USB Certification Guide from NXP for this.

Kind regards,
