Read back the inside of the microcontroller firmware, found some flash been tampered with, back to normal after burning, but again and again to electricity, also can emersion this problem, now we are sourcing for 30 k, this problem is very frequent, software is used to do well, haven't seen this problem before, please help to analysis, we put the ok product and fault switching chip, bad chips still appear this problem, the proof is not other problems of the circuit and power supply, software has limited the scope of data, using the watchdog, etc., all cannot solve the problem, doubt is bad chips, please help analysis,

CodePudding user response:

Write the software part of the FLASH to try to block
Is there a voltage monitoring function reset circuit?

CodePudding user response:

Who can solve the problem, look at how much,

CodePudding user response:

Reset is not, is the RC reset,
OK, first to block,
