[yocto] Noobie questions

[bahjat khan]

Hi Guys,


I'm extremely new to the yocto project, i've done quite a bit of reading on it but i'm still very confused.

I've set my self a simple task of changing the kernel for a Yocto image that i build, the commands i use to build this yocto image are:


 $ git clone http://git.yoctoproject.org/git/poky
 $ cd poky
 $ git checkout -b fido origin/fido
 $ source oe-init-build-env
 $bitbake core-image-minimal
 $runqemu qemux86

I understand that i need to make changes to the poky.conf file to specify what kernel i want to use (i have a standard choice between 3.14 and 3.19).


However if i want to use a different kernel such as 4.4, i do this by making the changes in the poky.conf file, copying linux-yocto_3.19.bb file and renaming it to linux-yocto_4.4.bb. I also change the SRC_URI to "git://git.yoctoproject.org/linux-yocto-4.4.git;barcelone=1;branch=${KRBRANCH},${KMETA};name=machine,meta"

It doesn't seem to find the place where it needs to download 4.4 from even though it's on the yocto website. I can download it by simply typing "git clone xxxx"

Also i haven't changed the SRCREV_machine_qemuarm ?= "xxxxxxxxxxxx" numbers, because i don't know what they are or what the variable SRCREV_machine_qemuarm is.

With these warnings, it reverts back to 3.19 kernel.

I hope i've explained my problem well, but if you are still confused please let me know.

Kind Regards,

Bahjat Murrad
