BB-AI. To power up the device requires the power button to be kept pressed for 15 seconds

[nmingotti]

In a BeagleBone-AI to power up the device, instead of pressing shortly the power button once, to make the machine boot it is necessary to keep the power button pressed for 15 seconds and the release it. In the old OSes apparently the problem is inverted, power-up works as expected, power-down doesn't work properly.

I saw the problem appearing in 2 different BB-AI devices. The tests below were run in a brand new BB-AI just unboxed. No capes, no wires attached except for the USB-C cable.

With default operating system — boot eMMC
