USB OTG issue on i.MX8QXP

[AndreSilva]

Hi NXP Support,

I am facing issues when try to connect any device o to the USB otg port on i.MX8QXP mek board. I already tried a few bsps from 5.4.47 to 5.10.9 and the result is the same, even trying the image packages avaiable for download at nxp website.. It looks like the USB enters in a loop moding try to enumerate the device, actuallly, if I only conect the OTG cable it starts the loop, don't even need to connect any device, here is the log:

just after the boot I got: 

[ 35.908399] usb_otg1_vbus: disabling 

and when I connect the cable:

and this messages keep coming until I have the cable connected, I also tried different cables. Could you please tell me how to fix it ?

I really need to get an USB camera running on my system.

thanks,

Andre
