shutdown problems

I just purchased a new Beaglebone Black RevC and I’m starting to experiment a bit. I’m seeing some strange behavior when trying to perform a graceful shutdown of the board. When connected through the micro USB shutdown works as expected. When an external power supply is used, and I’m connected through Ethernet, I can’t get the board to shutdown properly.

Following are my two experimental cases:

Case 1 - Power through USB

  1. Start with all cables unplugged

  2. Connect to laptop through micro USB

  3. Lamp for 5V power turns on.

  4. Beaglebone boots in about 30s

  5. Push power button on Beaglebone

  6. Beaglebone shuts down in about 6s

  7. All LED’s are off.
    Case 2 - External power

  8. Start with all cables unplugged

  9. Apply external 5V power.

  10. Lamp for 5V power turns on.

  11. Beaglebone boots in about 30s

  12. Push power button on Beaglebone

  13. Nothing happens!
    In each case, I also tried connecting through an SSH session. In both cases, pressing the power button is issuing a shutdown command. I also tried explicitly issuing a shutdown command through the SSH session (i.e. shutdown -h now). When powered through USB it works; when powered externally the shutdown doesn’t occur.

Any ideas or suggestions?

Based on your error, I thought it might be that one. Any chance was
this one of the first embest boards? I know they has flashed a few
boards with an early pre-released version of the debian image. (this
was fixed in 2014-03-31)

sudo rm /etc/systemd/system/getty.target.wants/getty@ttyGS0.service
sync

(hard reboot/reset)

Robert,

This looks to have fixed the problem.

Regarding the source of the BBB, I don’t know if it originally came from Embest; I purchased in through a major online retailer.

I presume updating Debian to the latest image would also have corrected this issue? Perhaps I’ll give that a try next.

Thanks very much for the help.

It has an embest logo on it, sold by element14.

Correct:

The first 4 Gig RevC board I got was an Embest board and it had this
version of the software loaded, so it looks like they haven't updated in
a while and are still building/shipping with the March release.

I simply re-flashed with a current release and it's working fine.
