There have been no kernel changes at all ? If this using gcc 4.8, then document it. We haven't fixed ARM boot support for gcc 4.8, so these images should not be using gcc 4.8 as their default compiler, and we won't be fixing all of these via defect. So if this is 4.8, return it to the platform domain and indicate they should be setting the preferred version of the toolchain to a version that is known to work for these boards. 33305 2 ning.zhang 2013-05-27 07:59:53 +0000 (In reply to comment #1) > What's the important change here ?

Hi, I rebuild a beagleboard image locally (master: 176a46b088135f2891983bb8540bc45389341d90), it could start up well. And i check the gcc version is "gcc-4.7.2-r20". But i am not sure the gcc version of the http://autobuilder.yoctoproject.org/pub/nightly/20130521-1 images. I only got the image files, but can not check the gcc version with the image. 33378 3 yi.zhao 2013-05-30 02:15:03 +0000 For the new build from http://autobuilder.yoctoproject.org/pub/nightly/20130528-2/ . The system can boot up without problems. 33397 4 dvhart 2013-05-30 14:50:50 +0000 This was the result of a MUT build pulling in gcc 4.8 into sstate and the AB not rebuilding with 4.7. This is expected behavior as a change in the toolchain is explicitly prevented from triggering a rebuild. We will track this with the qemuarm kernel boot failure, Bug 4549. *** This bug has been marked as a duplicate of bug 4549 ***
