Hi There,

We have done a imx6q based design and board bring up is going on.

All the power rails, clk, por are okay..(We followed our development board's power sequence which is working) but when we tried to connect OTG port to a computer it's not detecting it.

Board is not booted yet ..(no SD boot option provided)

Any help will be appreciated.

Thank you

Vishnu

HI Vishnu

one can check VDD_VBUS_CAP voltage and

check 24MHz frequency, if it is not stable usb communnication fails.

For testing one can load uboot with jtag, then test usb:

usb start , fatls usb 0:1

From PC (preferably with XP OS) one can run MFG Tools and connect board

with usb cable.

Best regards

igor
