I need help to investigate the following problem:
I use in my project autobahn to communicate with python on linux side asynchron.
Sometimes Yun is not reachable over wlan, if I connect in this case wired ethernet, I will see the connection on the router, but I cannot connect via putty and connection over ip via browser is also not possible. but linux is working partly, because the python script ist running, because linux is responding on the serial interface to the 32u4.
If I reset the linux (hardreset) everything works fine for several hours or days, then it crashes again.
What can I do, to investigate the problem. Are there logfiles activable to see the history after the crash?
Yun uses ar9331 which made by qualcomm has wireless radio interferes with the USB clock PLL after few hours (hardware bug). qualcomm release patch to work around it. the new OS include that patch.
