Hi Ben, I believe that having the boot partition aligned to 4MB boundaries can cause problems with old x-loaders, so by default the Linaro media create scripts only align the non-boot partitions to 4MB boundaries. You can override this by adding --align-boot-part to your linaro-android-media-create line. If my reading of the code is correct by default boot partitions will be aligned on sector 63 unless they are a Snowball, Mx5 or Samsung board, which all have their own requirements for where a boot partition should be and ignore the align-boot-part flag. Hope this helps, James _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
