I recently added an external 5V supply to the BBB barrel jack because I am going to add a relay cape.
If I issue “sudo shutdown -h now” the BBB looks like it is going to shutdown judging by the messages on the Jtag port but then re-boots?
See messages below.
I am using USB connectivity. If I unplug the 5V adapter and issue “sudo shuwdown -h now:” it works.

Thanks
Sorry i can't re-produce this on a BeagleBone Green..
Please run: sudo /opt/scripts/tools/version.sh so i can more easily validate..

Regards,
Tarmo,
Thanks. That would explain why another guy does not have this issue.
My thought is to do away with the USB → P.C. cable and go with Ethernet.
That way BBB only has 1 power source. Removing USB power then
sudo shutdown -h now works.
Ken
Have you tried 'poweroff"?
Ex:
sudo poweroff
Cheers,
Jon
Jon,
Yes. Same result.
sudo poweroff
Re-boot. See my reply to Tarmo.
Oh, you were using both the USB power and the Barrel Jack power?
Is this supported?
I always thought it was one or the other; not both.
Jon
Jon,
Originally when I got the BBB I only needed power from the USB cable.
However after adding a “cape” I needed more power. So the 5V
barrel power.
After looking over the schematic for the BBB and the TI 65217 power
management IC it appears it will take power from either. And if one
drops it will use the other.
That’s why I am moving to an Ethernet connection.
Ken
