Dear all,
I am setting up my Odroid XU with yocto using the core-image-minimal
receipe. Almost done and I am able to boot the system and log in via
screen (UART), but..
The network is not present at start-up. When I do lsmod I just see "Not
tainted" and no modules are loaded.
The module I need to load is the smsc95xx module. When I tried to load
the driver with "modpobe" it could not find the driver (although it is
in /lib/modules/3.4.98-custom/kernel/drivers/net/usb)
I had to manually add it to /lib/modules/3.4.98-custom/modules.dep
(which was empty after the bitbake process in rootfs)
So I added
"kernel/drivers/net/usb/smsc95xx.ko: " to modules.dep.
Then I could load it with modprobe. In order to load it at startup
I created a /etc/modules with the content "smsc95xx". Now my question:
Is there an easier (bitbake) way to make the modules load at startup
without editing configs on the target device? Am I missing something?
Does core-image-minimal not include network?
Cheers,
Markus

Hi Markus,
Please try core-image-base instead of core-image-minimal. That should
provide you with the necessary network support.
Best regards,
Rudi

Hi Rudolf,
same result with the core-image-base.
It seems that depmod is not run before building the image/modules in the
deploy folder. I have a custom kernel recipes. How can I make bitbake to
run depmod -a on the rootfs?
My recipes inherits kernel
and requires
recipes-kernel/linux/linux-yocto.inc
Cheers,
Markus

Ok, in this case you want to use
module_autoload_<modname> = "modname1 modname2 modname3"
in your kernel recipe (or distro or machine configuration which is
actually preferable). For example
module_autoload_smsc95xx = "smsc95xx"
The module-split class should pick it up and add the module to
/etc/modules-load.d/modname.conf.
Cheers,
Rudi

Thank you for the info.
Solved it the following way:
I added
IMAGE_INSTALL += "kernel_modules" to my local.conf.
Now SMSC95xx (plus some other modules, like joydrive) are autoloaded on
boot.
Cheers,
Markus
