Hi Hsu,

The Beaglebone Black turns on immediately because the supply is 5V into the AC rail.

When the power source is just a battery on the BAT rail, a push-button press is required to start the system.

Are you designing a new system or debugging an existing one?

Hi Sir,

Yes, I am designing a new system about AM3352 process.

My customer is connecting power source on the BAT. But it is not work. It is pluging adapter and turn on system. PB_IN is not working.
