Can yo provide more information on the test you are trying to perform? What is the status of the CE pin? Are there any protections triggered which will prevent charging?

1：We can directly connect EVK for charging -->>EVK-REG.log

2:But the IC we stick on the PCB cannot be charged -->>MY-REG.log

Can you help me check if there is an exception in the register?

Thanks
