Hello,

I’m used the install Ubuntu 13.10 OS on the two Beaglebone Black. (Testing the small web server)

However, when the reboot will not boot. ( Input the “shutdown -r now” command after connected the ssh. )

One device is a all LED is on always, not boot and connect. (Rev A5C)

The other device is a first LED is Blink always, but not boot and connect. (Rev B)

Apache, php, mysql other than software has not installed.

Please advice about how to solve this problem.

Can you connect a serial cable and capture the console logs?

See:

The serial cable plugs directly into the Beaglebone, and is used to debug problems with the unit.

Make sure all flow control is of. I’ve purchased some cables where TX and RX are reversed, check that well
