Hi,

  We have a custom imx6 based hardware powered with Li-ion battery, our board has option to charge from either wall AC adapter or through USB connected to a host USB2.0 ( PC/Laptop ). As USB 2.0 can give current either 100/500mA.

  My question is without any modification to USB cable is there a way to know how much current is being drawn by my board from USB 2.0 host, does imx6 has any register to display it ?

 

Thanks,

Manjunath
