UR connection mode is defined with the HWrst reset mode

[non]

Hello all developers Today I came to ask for advice. I have an STM32 Nucleo-144 development board with stm32H723ZG. At first it worked fine. But suddenly there was a problem of not being able to connect to the stm32cube programmer. I was wondering why the Voltage was about 0 volts.

Hi @non ,

Try to connect your device under reset. Here some other recommendations that may help you in the article How to solve debugger connection issues.
