installation of kernel modules

installation of kernel modules

[S.Jaritz]

[-- Attachment #1: Type: text/plain, Size: 2169 bytes --]

Hej

I have a problem when running do_rootfs() with some own kernel drivers 
included.

My kernel recipe builds some easy GPIO drivers.

# They come as one package:
myKernelModules:
        -> a.ko
        -> b.ko
        -> c.ko

# I build a recipe which creates:
myKernelModules.bb
        -> packages-split/myKernelModules
        -> packages-split/kernel-module-a
        -> packages-split/kernel-module-b
        -> packages-split/kernel-module-c
        -> packages-split/myKernelModules-.....

# I try to pack/install my Module by adding to layer.conf:
 
IMAGE_INSTALL_append=" myKernelModules" 

When I try to build the rootfs I got that error:

The following packages have unmet dependencies:
 myKernelModules : Depends: kernel-module-a but it is not installable
               Depends: kernel-module-b but it is not installable
               Depends: kernel-module-c but it is not installable
E: Unable to correct problems, you have held broken packages.

Any idea how to fix this problem?

Regards!

Stefan Jaritz

Take a look at deploy folder if your packages (rpm in my case) are
being created. I have faced problems where files go to -dev.rpm
packages and the yocto silently refuses to create empty .rpm package.

Hej  Daniel,

Building the modules as rpm works fine but it fails for deb. The deb 
generation process seems a little buggy. I have discovered problems with 
naming recipes (the QA tries to find the license by a "lowercased" link).

I checked the package dir. It is fine. The 3 files (a.ko, b.ko, & c.ko) 
are placed rightfully. The splitting into packages produces 3 kernel 
module packages and the 6 standard packages(like dev, static, local, etc). 
I think the problem is that the module will be compiled and deployed 
together with the kernel and the common packages later at the do_rootfs. 
That's why the myKernelModules recipe is deployed at the tmp/wok/<kernel> 
dir (and not at the tmp/work/<rootfs>).

Regards,

Stefan Jaritz

Hi Stefan,

Can you share your log.do_rootfs?
