Re: [Ltib] Building a external kernel using LTIB

[G.Muruganandam]

Hi Stuart,

Thanks for the steps. I did try your steps and also I went through 
the docs dir inside ltib installation.
But during the build, ltib still looks at the old kernel's ( kernel 
inside the ltib)  config file instead of the
one mentioned in ltib configuration for the external kernel and 
failed with build errors.

So I went through "LtibCreateNewTarget" file and followed the steps 
to include the new kernel inside the ltib.
I am able to partially build the kernel and it failed during the 
parsing of .dts file.

BTW linux kernel version 2.6.23 came with ltib 7.2.1 (1.305)
I am trying to build linux version 2.6.27.18 downloaded from 
kernel.org using the same ltib

My understanding, after going through .dts file from 2.6.23 and 
2.6.27.18, is that there are some
syntax differences that the current version of ltib unable to parse. 
This could/may be the cause.

For eg: The error message below indicates that it failed at the following

 /dts-v1/;

This line was not there in the kernel 2.6.23 .dts file.

So my guess is that it is more of ltib specific than the freescale.


Pl let me know, if you have any suggestion to fix this build error.

Thanks
G.Muruganandam
