Hi  Guys,

      We are working for DM3730 CPU,and use PMIC TPS65951. By now ,we use all  TPS65950's driver for TPS65951,and the system boot is OK,But when i use USB OTG functions,i have some problem.When  the OTG used as USB HOST,there is a bug:

1>we need insert the USB device to OTG port before system boot.

2>after system booted, i can read or write the device,but when i reinsert the device ,it will can not use .

3>if i booted the system ,then insert the usb device to OTG port , it will can not detect the usb device.

Is anybody have some suggestion?

Thanks

Tommy

    Hi Yuliang ,

    We are facing problems enumerating the OTG port for the host functionality .

    Im getting Vbat on the VUSBIN>CPOUT pin instead of 5V .

    What is the voltage you are getting on CPOUT pin on your board ??

    Regards,

    Rajesh N
