Hi @qimao-marvin 

The password and LC config word seems to be correct, I can see no problem here.

Isn't HSE firmware installed on this device? Could you check HSE GPR register at 0x4039_C028? If HSE firmware is installed, the LC config word is ignored and the life cycle needs to be advanced via HSE service. 

Regards,

Lukas
