[Buildroot] sky2 not created

[Buildroot] sky2 not created

[Laurent Joli]

Hi ,

My Host : Ubuntu 14.04

I would like to build for an qmx6 board from congatec.

So, I do :

 make qmx6_defconfig

When I ticked for Marvell driver : SKY2 and  SKY2_DEBUG

At the end of the build, I have not sky2.ko in my rootfs.

What can I do for obtain sky2 drivers ?

Thanks,
Koax

Depends on how you enabled these drivers: as a module, or statically
linked into the kernel?

Also, what was your exact flow of work?

Basically, you need to do:

	make qmx6_defconfig
	make linux-menuconfig
	... select the sky2 driver ...
	make

Best regards,

Thomas

Dear Thomas,

First of all, Thank you for your answer.

I would like create *a sky2.ko as a module.*

I use buildroot-2015.05-rc3 and do what you say :

make qmx6_defconfig
        make linux-menuconfig
        ... select the sky2 driver ...
make

So, after the complete build, I have this "*.ko"

Ok, your directory is named
linux-9bafbcba67f7bb2a48a5e05998cecb1165aa444f, not linux-3.10.17. So
just check the .config file in this directory.

Best regards,

So the driver is configured to be compiled statically in your kernel,
which explains why you don't have a kernel module generated.

(Could you talk with your mail server admin to avoid including such
stupid e-mail footers? Asking to keep information confidential when
sending e-mails to a public mailing list doesn't make much sense.)

Thanks,

Ok, I see now.

But When I boot with this rootfs ( ext2 ) on my board, I have :

buildroot login: root
#
#
# lsmod
Module                  Size  Used by    Not tainted
# modprobe sky2
modprobe: module sky2 not found in modules.dep


Thanks you,
Laurent

I think you should do some research about how to do the kernel
configuration.

If you enable a driver to be compiled statically, it is compiled
statically inside the kernel image, and there is no kernel module.

If you enable a driver to be compiled as a kernel module, then you get
a kernel module.

Since you selected your sky2 driver to be compiled statically, then
obviously you don't have a kernel module.

Best regards,

Thomas

Ok, Thanks for all this information.

I will continue to search on kernel configuration.

And use sky2 module dynamically kernel

Best regards,
