Hi @ChienNQ,

USB1_ID pin muxing is available on GPIO1_IO10 only. One can check the same from the Config Tools for i.MX Applications Processors.

Thanks & Regards,

Hi @ChienNQ,

I hope you are doing well.

The USBx_ID is muxed with GPIO. One can refer to Page 1350 of i.MX8MP Reference Manual.
USB1_ID --> GPIO1_IO10
USB2_ID --> GPIO1_IO11

To implement the USB OTG functionality without USB-C, one can refer to the below-mentioned link which is valid for i.MX8MP as well.

I hope it helps.

Thanks & Regards,

Hi @riteshmpatel ,

Thanks for support. 

We build our device form compulab SOM UCM-iMX8PLUS . 

And they did not connect GPIO1_IO10 to SOM. Can i use another GPIO like GPIO1_0 for ID function?

Please see this link for more detail https://www.compulab.com/wp-content/uploads/2022/03/ucm-imx8plus_reference-guide_2023-01-12.pdf

Thanks and best regards,

Hi @riteshmpatel ,

Thanks for support us. 

One more question, in case IMX8MP Plus is in bootloader mode, is it always in device mode? and regardless of the state of the ID?

Thanks and best regards,

Trend Nguyen
