It's not an award winning topic... but I'm able to freeze a BBB in a very
easy and repeatable way.
I'm trying to realize this http://www.guiott.com/Lino/index.html.
The GUI is written in HTML5 using node.js via web socket on BBB with Ubuntu
13.04 (ARMhf)(http://www.guiott.com/Lino/HLS/LinoConsoleSerialComm.htm)
(https://github.com/guiott/lino-console).
The streaming is with mjpg-streamer from a Microsoft LifeCam HD-3000 on
the same USB hub of the TP-LINK TL WN722N WiFi adapter... and here are the
problems :-( the BBB freezes often for some seconds (watchdog process
arise on "top" window with more than 90% of CPU) if both streaming and web
sockets are working. The heartbeat led too stops blinking.
If I use a 1280x720 frame streaming I'm also able to stuck completely the
BBB with all led stopped. It's not a problem of stream frame loss, it's a
real OS problem.
node.js is 0.10.22 version and I tried with any version of mjpg-streamer.
The BBB is powered with an external power supply with 3A capability.
Could anyone please suggest me some more tests to perform? Do you think it
could be a problem of driver (webcam or WiFi stick)?
Thank you in advance for any suggestion you can give me.
Guido
