i suspect this is an armv7 soft-float vs hard-float mismatch. Either your prebuilt OE system is configured with soft-float and the toolchain you use compiled for hard-float by default, or the other way around. can you check how you've compile HelloWolrd and check the other ABI? -- _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
