The machine configuration file should be setting the 'DEFAULTTUNE' variable to an appropriate ISA and ABI (hard float) for your configuration. If it is not, you may have to create your own variant and change the DEFAULTTUNE setting -- assuming the board supports the necessary hard float components. (And yes, there are some armv7a variants that people removed the VFP instructions from -- even though it's theoretically against spec.) --Mark > Cheers, > > Richard > -- _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
