Yes this is intentional. u-boot only starts the network driver when it needs to use it (i.e. to send a ping or download something over tftp). After it has finished the network driver is stopped. Any traffic on the network will be ignored if u-boot isn't actively trying to perform a network operation, even if it is addressed to the device. > I have only tried the MX6Q Sabre auto device, since this is the only device I > have now. > > Thanks for the feedback. > > John > _______________________________________________ > U-Boot mailing list > [email protected] > http://lists.denx.de/mailman/listinfo/u-boot _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
