About the problem of software restart of STM32duino
I have two questions as follows:

1. When the stm32 accidentally crashes due to the single use of stm32, the stm32 will only be stuck there, while the 328p will automatically restart.
2. When I artificially want to restart stm32, generally speaking, I will write the following program on arduino. With this program, 328p will restart, while stm32 will be stuck there and will not restart.
   Looking forward to your reply, I wish all the best!
   `#include <Arduino.h>
   void(* resetFunc) (void) = 0;//定义重启变量

void setup()
{
Serial.begin(115200);
Serial.println("启动成功");
delay(1000);
}

void loop()
{
Serial.println("重启");
delay(1000);
resetFunc();//重启
}`

There is no issue. STM32 Simply fallback to an error handler. And often it ends with a while(1).
Try
NVIC_SystemReset();

Most of those error handler are weak and can be redefined.

Thank you for your reply, your method is very effective! So if I want the program to be able to restart itself when it crashes, I need to write my own watchdog program?

[JingtaiChen]

I wonder how to do that?

And please avoid to open issue for question. Use the forum or GitHub discussion. But you will get better audience on the forum.

ok
thank you for your reply

Or use this library provided within the core:
