Unable to get kernel modules

Unable to get kernel modules

Hi,

I am building my image with : bitbake poky-image-minimal-live
But after booting/installing this image, lsmod, does not show any modules
loaded into the kernel. Also, the folder */lib/modules/2.6.34.7-wr-standard* in
the rfs does not contains the following files/folders:

   - modules.builtin
   - modules.order
   - kernel

Though they are present in the *
tmp/sysroots/core2-poky-linux/lib/modules/2.6.34.7-wr-standard.*
*
*
Also, while building, *modules-2.6.34.7-wr-standard-r12-atom-pc.tgz* is
formed in tmp/deploy/images, which consists of the above mentioned
files/folders, but does not seem to be integrated into the image.

Can anyone please suggest/guide me how to integrate loadable modules into
the image.

By default the minimal image doesn't include all the kernel modules. You
can add them to the minimal image by adding "kernel-modules" to
IMAGE_INSTALL in meta/recipes-core/images/poky-image-minimal.bb

Cheers,

You can also add them individually if you don't need them all. Every
module is built as a separate package to make this easy. If you have a
machine for which certain modules are required for normal functionality,
you can add them to:

MACHINE_ESSENTIAL_EXTRA_RDEPENDS

in your machine config.
