Many Thanks for your answers. Thus I was thinking of making 2 separate linux.bb, one for deployment and the other for debug (i.e. linux-debug.bb) and update PREFERRED_PROVIDER_virtual/kernel accordingly. But is there an automatic way to select proper .bb (linux.bb or linux-debug.bb) file like setting this variable(PREFERRED_PROVIDER_virtual/kernel) within the .bb image file ? Won't it work ? Another option which is coming on top of my mind: SRC_URI_append_<image-name> = " file://configuration_segment.cfg" Is it something realistic and working ? Please advise Many thanks in advance -- _______________________________________________ yocto mailing list [email protected] https://lists.yoctoproject.org/listinfo/yocto
