OK understood. How important is it that we use vold for sdcard (rather than by-name in init.rc)? alternatively, we could install vold during install in lmc and during lava install and set the correct value there. Note: on mx5 we have a 1 partition offset because there is an additional non-data-fs partition for u-boot on sdcard. -- - Alexander _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
