linux-yocto defaulting to 3.4.52 for new qemuarmhf.conf
|
Elvis Dowson
Hi,
I created a new qemuarmhf.conf, to build using armv7a vfp and neon. In the linux-yocto_3.8.bb recipe, I explicitly specified SRCREV_machine_qemuarmhf and added qemuarmhf to the list of COMPATIBLE_MACHINES. For some reason, it still refuses to build using kernel 3.8, and keeps defaulting to 3.4.52. I know I can over-ride it in my local.conf by setting a PREFERRED_VERSION_virtual/linux ="3.8" , but I'd like to know what I've missed, to get it to work by default, without setting the over-ride in my local.conf. Thanks! Best regards, Elvis Dowson |

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? Best regards, Elvis Dowson |

Hi Bruce,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. Cheers, Bruce Best regards, |

Hi Bruce,

Why does it attempt to use the 3.4 recipe? 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.

Hi Bruce,If you are using yocto and poky as the reference distro: ./conf/distro/poky.conf:PREFERRED_VERSION_linux-yocto ?= "3.4%" Is where you are getting the default to 3.4. I plan to bump that once we've shaken all the issues out of 3.10. Cheers, Bruce
