BQ25713: Failed to charge for unknown reason

Part Number: BQ25713

Hi,

We have some boards that charging didn't start after adapter plug-in with unknown reason.  At this moment, the register dump looks like below.

From above, I found REG0x20[3] is set to ‘1’ indicating SYS_SHORT.  After writing REG0x00[6]  to '1' and replug in the adapter, charging still not started.  At this moment, the register dump looks like below.

Please suggest what can be the next step to debug on this board?

Thanks,

Antony
