Yesterday I posted the following note: *********************** Jan 6 (14 hours ago) I just got a new BeagleBone Black and have flashed Debian 7.9 successfully. I was connected with USB to a Mac running OSX 10.10.5 Yosemite. I was using a 5v 2A power adapter and a TP-Link TL-WN722N wifi adapter. I used both with another BBB for about a year with no problems. I was in the process of adding the Adafruit wifi-reset script to the startup services when the BeagleBone died. Nothing else was connected.
Now whenever I try to boot the system, there is a single momentary flash of of the power light and thats it. Is this likely just bad luck on my part? Is anyone else having this problem? Thank you Fred Patrick ************************* I just ordered a new BeagleBone Black which leads me to ask some more questions: 1) Is anyone aware of failures caused by defective 5v wall adapters? 2) My understanding was that the external 5v supply took over whenever it is plugged in and that I could plug in the USB connection without worrying about interference or problems with power supply. 3) Before the board crashed, I had both the 5v 2a adapter and USB connector to Mac plugged in. If I issued a shutdown -hP now on BeagleBone using ssh on USB connection, the BBB would shutdown and after about 4 or 5 seconds the BBB would reboot with no input from me. Is this expected behavior? 4) My plan for the new BBB is to flash the eMMc with my existing microSD card, plug in the wifi adapter, boot the board from eMMc with power from USB connection, plug in 5v 2A wall adapter, setup wlan0, bring it up and download wifi-reset, add it as a service and reboot w/o the USB connection. Is there any known reason that this will not work.
