How to rebuild the kernel after some changes in the source code.

SyedRafiulHussa — Thu, 02 Feb 2012 23:23:45 GMT

Hi,

I am new to the kernel programming and also to the iMX53 QSB. I would like to change some part of the kernel and rebuild the image. I would be very much happy if someone could give me some pointer how to do that.

Thanks.

To get kernel sources (in <LTIB>/rpm/BUILD/) under LTIB :

./ltib -m prep -p kernel

After changes in kernel sources in order to build the kernel :

./ltib -m scbuild -p <package>

To deploy it

./ltib -m scdeploy -p kernel
