Base AAA stacked on CORE S3 SE.

void setup() {
  auto cfg = M5.config();
  cfg.output_power = false;
  M5.Power.begin();
  M5.begin(cfg);'

This code boot from the battery.
But, this code does not output +5V to the port.

cfg.output_power = true;

In this setting, CORE S3 turns on for a moment and then turns off.

I changed the settings within loop.

M5.Power.setExtOutput(true);

+5V is output, but CORE S3 turns on for a moment and then turns off.
If USB is connected, it works fine.

I am having trouble using the sensor connected to the glove port.
Can anyone give me some advice?
