Hi,

I am trying to make work the example ping-pong rpmsg, the compilation:

bitbake core-image-minimal

 

gives not the module that should be in

/lib/modules/3.14.52-1.1.0_ga+g5f6f0a5/kernel/drivers/rpmsg

 

So, looking for an answer I found someone that says that you should add "kernel-modules" to local.conf

 

so I did that:

 

$ MACHINE=imx6sxsabresd source fsl-setup-release.sh -b build

 

I added the next line to file ~/build/conf/local.conf :

 

IMAGE_INSTALL_append = "kernel-modules"

 

and next:

 

$ cd build

$ bitbake core-image-minimal

 

 

But the modules are not in the folder, could you advise?

 

by the way, does it means where in the file local.conf add the line? I have added this on top, the very fist line

 

I need understand how it works, so, where can I get the source code of imx_rpmsg_pingpond.ko?

 

It's a little bit urgent

 

thanks in advance.
