Hello Zoran, thanks. As far as I understand is thumb2 another mode of coding, that might create more compact code. But I want to keep all compatible to my previous tool-chain and settings. The only file where I can found this "cortexa9t2hf" is ./meta/conf/machine/include/tune-cortexa9.inc but I can't see how I can control Yocto to generate "cortexa9hf-neon" as before. Or have I been wrong the time before?
bitbake gives me in 2.5: TUNE_FEATURES = "arm armv7a vfp thumb neon callconvention-hard cortexa9" TARGET_FPU = "hard" and in 2.7: TUNE_FEATURES = "arm vfp cortexa9 neon thumb callconvention-hard" TARGET_FPU = "hard" so armv7a seem to be missing. In terms of thumb both is same. But is that the reason? Where to set it? Arno > > Hello Arno, > > Your question, per say, has little to do with YOCTO forum.
