hello.
this is the first time I've had this problem , I describe this problem next:
1 the io initialization input is normal (this is the feature I want)
2 when I power off and restart, I find that the same pin initialization input is not responding
3 repeated power-off / power-on operation the pin initialization input sometimes does not respond
why does this happen, please tell me
thanks

Not sure what you mean by "io initialization input is normal", but:
1. Check if BOOT0 pin is at logic LOW (connected to GND directly or via resistor).
2. If there is a high-capacity capacitor (like 1000uF) in the power supply path, wait longer between power off and power on, or use Reset button.

thank you for your help
1. "io initialization input is normal" means that the pin function i want is the input function.
2. just like you said, BOOT0 pin is at logic Low
3.max capacitor of the power supply is 100uf
thanks

Hi @shan chen ,
Please share your minimal project, not only the main file (if possible the .ioc file). So the members of the community and us can help you.

thank you for your help
sorry, i tried many times, the .ioc file transfer failed
do you have any suggestions about the problems I mentioned or have you encountered similar problems before
best wishes
