Glad for you!
It's strange, in my project P1.7 is unconnected, and 4G modem works like a
charm for 24/7.

I want to follow up on this post in the event that someone else is
experiencing the same problem.
I implemented a USB power switch as shown in the below schematic. I have
not seen a recurrence of the hot CPU problem after much testing. The 3G
modem and software have been working perfectly.

Its OK when PB turns on.

Thank you for the reply. The drawing is very helpful.
I noticed that P1.03 EN blinks high, then low, then high again after a
couple seconds. I assume that this is not a problem for the power switch.
I'll be checking this further after I get my hands on the component.

Thank you for your
Thank you for your comments. It seems I must revise the design for the
power. It's a bit out of my area of knowledge so will need to do some
research.
The Beaglebone Black has always worked perfectly for my application but the
PocketBeagle does not have the same USB socket available so I wired
Agreed. 3G modems can pull a remarkable amount of power (up to 2A!) under
certain circumstances.
That's going to tax the power systems of the PocketBeagle pretty heavily.
You need to have something which you can use to turn on/off the power to
the modem which bypasses the PocketBeagle power s
AP2192 for example.

Hi! Propably the trouble is in the wrong power circuit to USB modem. Use
the USB power switch to power USB device connected to PocketBeagle board.

One further note, during today's test, the temperature returned to normal
after restarting the bonescript only. I did not cycle power. The script
controls wvdial to connect the 3G Modem. One theory is that there is some
state between the CPU and modem that makes the CPU run hot and this is
