Robert Nelson, About the service /etc/init.d/networking
did you modify it for the beaglebone black ? Because we know that the BBB have problem with ethernet. But where did you try to correct the problem ? In the networking service ? Did you put a sleep ? Where can I reduce the time of the execution of this service ? micka, Le jeu. 19 mai 2016 à 19:48, William Hermans <yyrk...@gmail.com> a écrit : > *My apologies to All: I'm an interloper.
