I have an issue about the voltage of USB OTG DP pin of i.MX6.
In normal case, the DP pin should have a voltage change as bellow when the kernel is starting up.
※I measured it on i.MX6DLSabreAuto and connected the OTG port to PC.
But my customer met an problem. On their board, after the D+ pin rising to 0.6V, it will not fall down
and keep on 0.6V for ever.
Could you give me some advice to analyze the reason?(I think it is something about kernel,but I have not find it)
