Hello,
I'm trying to figure out how can I override machine settings, for example
in raspberrypi I want to change default kernel version from 4.4.x to 4.1.x
for that I created in my layer meta-somelayer/conf/machine/raspberrypi.conf
:
require conf/machine/raspberrypi.conf
PREFERRED_VERSION_linux-raspberrypi = "4.1.%"
when I ran bitbake it gives:
$ MACHINE=raspberrypi bitbake virtual/kernel
NOTE: Tainting hash to force rebuild of task
/home/zak/Projects/yocto/meta-somelayer/recipes-kernel/linux/
linux-raspberrypi_4.4.bb, do_compile
so it seems that bitbake ignored my override settings !
I'm using morty branch and my layer meta-somelayer has higher priority than
meta-rapberrypi :
$ bitbake-layers show-layers
layer path priority
==========================================================================
meta /home/zak/Projects/yocto/meta 5
meta-yocto-bsp /home/zak/Projects/yocto/meta-yocto-bsp 5
meta-poky /home/zak/Projects/yocto/meta-poky 5
meta-yocto-bsp /home/zak/Projects/yocto/meta-yocto-bsp 5
meta-raspberrypi /home/zak/Projects/yocto/meta-raspberrypi 9
meta-somelayer /home/zak/Projects/yocto/meta-somelayer 5
when I tried to override the setting in rpi.conf instead of
raspberrypi.conf in meta-somelayer/conf/machine/rpi.conf:
MACHINEOVERRIDES = "raspberrypi:${MACHINE}"
require conf/machine/raspberrypi.conf
PREFERRED_VERSION_linux-raspberrypi = "4.1.%"
and running bitbake with :
$ MACHINE=rpi bitbake virtual/kernel
NOTE: Tainting hash to force rebuild of task
/home/zak/Projects/yocto/meta-somelayer/recipes-kernel/linux/
linux-raspberrypi_4.1.bb, do_compile
it worked !
My objective however is to override the machine settings and keep the same
MACHINE name.
Any Ideas?
Regards,
