Problem with debugging using keil

ZYang.2

Hi 

I was using Keil 5 to debug my code on #1 board, somehow the code was kind of stuck, it has no response to reset, and cannot run anywhere, the same code works with no issue on the other self-build board(these two are basically the same), this #1 board works also with no issue earlier today, this situation just suddenly happened. It has no problem with compile, download, enter debug mode.... I`ve drained my brain and cannot figure out what is wrong,,, any suggestions??

Thanks in advance.

Make sure BOOT0 pin is pulled low.

Check clock settings and sources.

Add code to report if Error_Handler or HardFault_Handler​ are entered.

Check you are reconfiguring debug pins or entering low power states.​

Thanks clive1

The BOOT0 is exactly the reason why the code couldn`t run. I noticed that the voltage on BOOT0 was somehow pull to 2.7V.
