IMX8MM mini UUU without type C connector

[dudisasson]

Hi,

I have a new board we designed according to the IMX8MM mini EVK. we removed the type C connectors and replaced them with an usb2 OTG connectors. 

I used the following link and compiled the Uboot & kernel with the changes mentioned there.

 https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/i-MX8MM-i-MX8MQ-USB2-0-Design-Without-US...

Uboot - CONFIG_USB_TCPC=n

Device tree - 

&usbotg1 {
    status = "okay";
};

&usbotg2 {
    status = "okay";

and removed the references to ptn5110.

when trying to load them with UUU, this is what I get in the terminal:

Hi dudisasson,

It appear that all the configuration you did is good, where did you take the source code?
