Hi Bruce,

Another quick question, why is it that when I create a new qemuarmhf.conf machine configuration, it doesn't automatically pick up the latest linux-yocto_3.8.bb recipe? Why does it attempt to use the 3.4 recipe?

Are you working off master ?

Since you set the compatibility, it should have been picked. But something
else must be changed in your layers, since if you didn't add
3.4 compatibility via bbappends, it never would have been selected
at all.

Yes, I'm currently working off master. If I add the following qemuarmhf.conf file, and apply the patch to linux-yocto_3.8.bb, it still tries to compile linux-yocto_3.4.bb recipe. You should be able to reproduce this fairly easily at your end, with the current poky master. I'm not using any additional layers, just the core yocto default layers.
