About remaining the VDDUSB_CAP voltage in i.MX6DQ.

Dear All,

 

On custom board, VDDUSB_CAP connected 10uF and 0.1uF capacitors.

(On SABRE-SD, VDDUSB_CAP connected 10uF [C627] and 0.22uF [C633] capacitors.)

 

Because the discharge time of VDD_USB_CAP is too late, there is possibility of remaining the 0.6V voltage at the next Power ON.

Is there a problem in this voltage (0.6V)?

 

If the voltage cause the problem, could you tell me the workaround?

 

Best Regards,

Keita
