due to build system issues we don't build xloader from source atm. Patrik added a blueprint "build MLO from source" to the backlog before he left to vacation: - https://blueprints.launchpad.net/linaro-android/+spec/linaro-android-mlo-from-source With some luck we might tackle it for this cycle (or august since patrik is on summar vacation this month). -- - Alexander _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
