Resolved! STM32U585OIY6QTR ADC reading garbage values

I am planning to do an aging test which need capture the voltage of a net, but i found STM32U585OIY6QTR report a value about 40 while the actual voltage of ADC channel is close to VREF.Then i write a simple ADC demo to verify ADC configuration, and r...
