Building own kernel instead of taking from git

Building own kernel instead of taking from git

[jags gediya]

I want to build my kernel source code in yocto. For that i have
modified the required linux-imx.inc file.

Inside that i have given kernel source directory in SRC_URI and S variable.

Is this approach fine, or is there any better solution i can get?

I would always create my own layer and add a .bbappend for the
kernel-recipe I want to modify. There you could of course change the
SRC_URI and S variable but you could also provide your changes to
linux-imx.inc as a patch.

Then you could manage your changes to this layer via git. And you don't
lose the opportunity to pull changes from the remote repositories
without destroying your own changes.

I think all you need to know is available in the kernel-dev manual:
https://www.yoctoproject.org/docs/1.6.1/kernel-dev/kernel-dev.html

Generally I would prefer to copy and modify the linux-yocto custom recipe
(linux-yocto-custom.bb) like described in the manual. Furthermore creating &
working in your own layer would be a good idea.

regards,
richard
