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?
