Connectcore Imx6UL Micro AB OTG enable

Hi,

I am new to DIGI community, I want to enable OTG support on the micro AB in CC IMX6UL SBC Express. I have used the following setup in order to enable OTG for the Micro AB:

&usbotg1 {
dr_mode = "otg";
fsl,power-line-polarity-active-high;
disable-over-current;

status = "okay";
};

&usbotg2 {
dr_mode = "host";
fsl,power-line-polarity-active-high;
disable-over-current;

status = "okay";
};

But, Unfortunately I am not able to enable OTG on the micro USB. When I try drmode = "otg" @usbotg1, USB1 in host turns off and no longer detects USB.

Kindly, let me know for any suggestions.

Thank you.

Hi Igor,

I had gone through the link and tried it. USB host itself gets disabled. So, its not working. Is there an other way?

Thanks,
