[yocto] How to Create SDK

[Zhang, Jessica]

Hi Praveen,

If you want to create bsp, I'd think you need to build a image for the target arch.  For Yocto, the build system will use the cross compilation during the build process base on your meta-data and layer configuration.  If later your want to enable development work for your bsp, then you'll need to build a toolchain, as to what toolchain target, are you expecting to use qt? If not, then meta-toolchain should be fine.

Hope this will clear up the steps for you to create your bsp.

Cheers,
Jessica

 Hi,
     I am very new to Yocto so kindly help. I wish to create bsp for our project
in which we are using arm1136 processor. I have created a layer (meta_prj) same
as meta for our project and have made required changes in
meta/conf/bblayers.conf.sample to consider meta_prj for compilation of recipes.

Now what should be my first step? Am i supposed to cross compile toolchain
first. I have noticed we can download external toolchain, if i have to produce
one of my own how i can do it? Am i supposed to compile meta-toolchain-qte.bb to
get this toolchain?


Thanks & Regards,
praveen
