STM32 may crash, and it will work normally after rewriting the program [Copy link]

 

Today I used a domestic 32 chip STM32F103RBT6 to run something and found that the board did not work. The buttons and indicator lights did not respond. After powering on again, it still did not work. When I connected it to the computer and entered debug, it was normal. Why is this happening? I did not do anything else but entered debug once and re-burned the program and it was normal. Please help me, experts

Was it resolved later?

Fake death? The system got stuck at a certain line of code, or hung?

The code may have hidden problems. More testing is needed to find them.

Added a watchdog?

It should not be a simple fake death. I tried to power off and then on again, but it still did not work until I re-burned the program.

No watchdog

What operating system is it running? Freertos?

Just a bare metal machine with simple operations such as ADC on-chip flash reading and writing

Maybe the program in Flash was modified or deleted, causing the program to malfunction?

It should be a program problem, causing the system to be erased incorrectly or locked. In this case, restarting will not work.

If there is online programming code for program memory in the program, pay attention to the setting of running conditions to avoid wrong operation.

Check the electrical level. The pirated emulator is externally powered, and the electrical level may be unstable when the emulator is unplugged.
