When I tried to power STM32L432KC board externally with 5V supplying the voltage at pin 5V directly, it causes NRST pin to go low and the board becomes unresponsive, means there is no DAC Output connected to multimeter. Shall I pull up NRST pin externally? Please let me know your suggestions.
Is there any way to solve this issue or I miss any efficient way to power STM32L432KC externally with 5V? My goal is to run this board with external 5V power supply and want some DAC output.
