Moin Hinnerk,
(yes, exactly what you have said: "Moin" is the way to go!!! :)) 8)))))
The problem with the kernel sources here on the beagle bone side of
the street arises not from the kernel sources themselve -- so to speak
the Torvaldic parts of Kernaltica -- but more from the parts which
were implemented and designed to speak to the hardware itsself.
3.8.x has good "cape" support ("cape": additonal pluggable PCBs)but
less good USB and ethernet.
3.14.x has better ethernet and USB but does not switch off the board
if shutdown (aka "battery eater") and does random reboots. The GPIOs
for the "capes" have to be configured more or less manually with
3.14.x.
Now I am experimenting with 3.15.x...we will see.
The whole process from "I want" to "I have" is time consuming,
because each time a lot of sources are downloaded and my DSL is
"old school" ;)
Thanks a lot for your help!
Viele Dank für Deine Hilfe! :)
