In my constellation thumb interworking does not work. glibc is arm compiled, the rest is thumb format. To test it I added ARM_INSTRUCTION_SET="arm" THUMB_INTERWORK="no" to my machine configuration. But that did not help! Both variables are overwritten in openembedded/conf/dist/include/angstrom.inc. So I commented it out in that file and voila, the result boots correctly. Is there a more elegant way to solve this? Perhaps allow to configure this in the machine conf?
