The links are a little old though, so maybe newer qemu versions can configured to be stricter. https://stackoverflow.com/questions/19990756/aligment-faults-ignored-on-armv5te-in-qemu https://patchwork.ozlabs.org/patch/550535/ -- _______________________________________________ Openembedded-core mailing list [email protected] http://lists.openembedded.org/mailman/listinfo/openembedded-core
