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:
