Dear Expert

We are doing USB interface modifications of LS1028A RDB by connecting both usb3.0 interfaces to the M.2 connecctors for connecting 4g modem and we are not using any USB connector.

we are not using below usb interface pins

1. R_USB1_VBUS- not using

2. USB1_ID -connecting to ground with 1K

3.USB_DRVVBUS-not using

4.USB_PWRFAULT-not using

5.USB2_VBUS-not using

6. USB2_ID-connecting to ground with 1K

 

Is it ok? Please comment.

Hi @mkraj,

Please refer to Table 32 in the AN12028 for pin termination details if the USB interface is unused.
