Incorrect, as that won't work, the "-@" generates symbol information, for use as an overlay. In 3.8.13, we an early version of "dtc: Plugin and fixup support" A later version went mainline as of dtc-1.4.3: https://git.kernel.org/pub/scm/utils/dtc/dtc.git/commit/?id=20f29d8d41f6d1bd2fbe466aa5676026eb012832 Debian (and thus ubuntu) only has dtc-1.4.2 in the stable branches.. Sid recently got dtc-1.4.5 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.
