it's directly the mcu design.I use de default USART2 pin (PA2-PA3)I have tested with USART4 and all works fine.I think we have a real problem with this mcu G0B0 and USART2

Other thing, my STM32G0B0 is recognized as G0B1 (mcu sourced directly from ST) on the stlink tool.I have soldered this mcu on nucleo32-G031K8 for my prototype and already integrated on my final design.

Hi @Community member , i have tested yout proposition with simple led blinky and i have the reset on my STM32G0B0 (with uart2 disable).The break is handle nowhere, it's my problem and the origin of my idea about design mistake.
