Hi all

I have a question about boot sequence in i.MX6UL.

In Figure 8-2, there are a branch of "USB OTG1 Activity Detected".

I think the detection means USB Plugged-In Detector.

Am I correct ?

If no, please teach me what is the meaning of "USB OTG1 Activity Detected" ?

Hi Ko-hey,

Yes, you are right.  When USB OTG1 Activity Detected then execute Complete USB HID enumeration,due to activity detected. Finallly go to download the images. 

It means USB Plugged-In activity.
Have a great day,
Rita
