Re: [ptxdist] Modifing platform rules

[Alan Martinovic <Alan.Martinovic@zenitel.com>]

Hi,

I'm trying to add a new menu option in the platform Kconfig.

Here is what i did so far:
Copy the /usr/local/lib/ptxdist-2014.09.0/platforms/Kconfig to oselas.bsp/platforms

I've tested it and changes on the oselas.bsp/platforms/Kconfig are shown in the platformconfig.
I want to add a new top level menu entry.
I add:

menu "custom image creation rules  "
source "platforms/custom_image.in"
endmenu

to oselas.bsp/platforms/Kconfig and that
gives a "can't open file" when running ptxdist platformconfig

However, if I put an absolute path, everything works.

menu "custom image creation rules  "
source "absolute_path_to/platforms/custom_image.in"
endmenu


Relative to what path does the extended Kconfig look for .in files?

Do it in the platform. But the folder names differ. The *.make files should be still in the rules/ directory inside the platform directory, but the corresponding *.in file must be located in the platforms/ directory.

So, if your platform is located in configs/platform-myboard/ the kernel rules must be located in:

configs/platform-myboard/platforms/kernel.in
configs/platform-myboard/rules/kernel.make

Happy hacking
