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.

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 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
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

I'm using the PocketBeagle in one of my projects and have noticed 5 times
out of maybe 100 that the CPU runs very hot, enough to burn my fingers.
Running the TOP command, I see nothing using more that 1% CPU usage. When I
cycle the power, the temperature returns to normal. I'm concerned that it
Hello everyone,
I am using a BeagleBone Black to interface between a weather station and
radio modem. I am using two USB to serial converters and am experiencing
USB system crashes which I have not yet been able to solve. I am thinking
there may be some type of a conflict with the drivers when
The python module in pyserial is called serial, so no mystery there.
To run a version of pip for your python3.4 you can use "python3 -m pip [pip

I forgot to mention that I am setting the resolution via kernel command

resolution.

It appears that the USB3.0 port goes directly to the hub, so we will not be

On the Raspberry PI, USB is tied directly to a hub, so there's no way (
I've heard of ), to run it in 'gadget or peripheral' mode, even though the
CPU does support device mode. Will the X15 have this issue?

You will need to reinstall everything after updating the image. Knowing
it's a version issue though, you may be able to update the Cloud9 package
on your machine and it might solve the problem. I'm not sure how this is
done though. Check the Cloud9 docs.

Makes sense, thanks very much for commenting on this. I will keep my

Best I can tell, u-boot loads the kernel and the dtb file successfully but
boot locks up with "Waiting for root device /dev/mmcblk0p2..."
There are a number of things in the boot log that look

I might be able to continue using 11.10 but if at all possible we would
