You just stumbled on the biggest issue... Debugging's going to be fun.. Specially if the end user doesn't have a usb-serial cable.. After u-boot patches the device-tree, the kernel will never know.. (that's also why things, video/mmc/wl18xx will also just work better) Regards, -- Robert Nelson https://rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
