Hai,

I'm working in a project with STM32L433CCU3 controller,but controller not responding in a usual manner.Some time it responded normal and then it changes and it throwing error in STM32-IDE as below

Break at address "0x1fff3f36" with no debug information available, or outside of program code.

and STM32L433CCU3 pin no:44( BOOT 0) connected with Pull-down resistor but gives OUTPUT HIGH.

Anyone help me with this,what will be the solution..!

 

Thanks

What value of pull down?

Check netlist for other connectivity. 

Check blank or solder test board for shorts.

I have tried by using 10K ,4.7K, 1K Resistors to pull down,but still BOOT0 pin is HIGH.

Look to other causes..

BOOT0 is shared with PH3, then based on code and option bytes ... read

Sounds like BOOT0/PH3 is shorted to VCC.
