Re: HOW TO- Build modules for embedded platform?

[Vishal Kapoor <vishal.kapoor83@xxxxxxxxx>]

Yeah, you need to create a file system for your target board.And in that file system under /lib/modules you can install(dummy install) the modules, like if you want ebtables module then in Makefile you need to give : 

install:
    $(INSTALL_MODULE) net/bridge/netfilter/ebtables.ko  /home/user_name/your_fs/lib/modules/ebtables.ko

I think your taget board may be holding a filesystem/inital ramdisk. In order to make the modules part of the filesystem, you need to:

1. Install the modules to the 'lib' directory under the 'directory tree' from which you have created the existing filesystem for the TARGET.
2. create a new filesystem image from the above directory tree.
3. Flash the filesystem to the target board to the same location where the existing filesystem resides OR tell the kernel to use the new filesystem if you are specifying te filesystem in other methods.

HTH,
