---++ Add Wi-Fi support to Atmel SAM9M10-EKES and SAM9M10-G45-EK

This page will provide short information on how to build and install the Wi-Fi Linux driver on the Atmel SAM9M10-EKES and SAM9M10-G45-EK development boards.<br /><br /><strong>NOTE:</strong> This information should be used in addition to the instructions given on http://www.linux4sam.org<br /><br />To be able to use the owl wifi driver on the SAM9M10-EKES, the kernel must be patched and the owl wifi driver kernel module must be built and installed. This can be performed "standalone" or from the Angstrom/OpenEmbedded environment.

It is also possible to use a pre-built image that is provided by HD Wireless. See [[DemoSAM9M10EKES]] for information about the demo image.

This page will describe the two options for building and installing the Wi-Fi driver on the Atmel SAM9M10-EKES.
---+++ Adding Wi-Fi support to Angstrom/OpenEmbedded

When building a kernel and a rootfs using Angstrom/OpenEmbedded, the oe_at91sam-owl-wifi.patch should be applied to the oe_at91sam.tgz overlay tree (ftp://ftp.linux4sam.org/pub/oe/linux4sam_2.1/oe_at91sam.tgz).

First, follow the instructions at: http://www.at91.com/linux4sam/bin/view/Linux4SAM/OpenEmbeddedAngstromBuild#How_to_build_Angstrom_for_AT91

After applying the AT91 OpenEmbedded overlay tree, apply the owl wifi patch: [[%ATTACHURL%/oe_at91sam-owl-wifi.patch][oe_at91sam-owl-wifi.patch]]
<verbatim>angr@blorg:~/oe$ cd oe_at91sam
angr@blorg:~/oe/oe_at91sam$ cp /path/to/oe_at91sam-owl-wifi.patch .
angr@blorg:~/oe/oe_at91sam$ patch -p1 < oe_at91sam-owl-wifi.patch</verbatim>

Then continue with the remainig steps as described in "Setup local configuration" on http://www.at91.com/linux4sam/bin/view/Linux4SAM/OpenEmbeddedAngstromBuild#How_to_build_Angstrom_for_AT91

The kernel and rootfs image will now have wifi support, and the module will be loaded upon system start.
---+++ Adding Wi-Fi support to a "custom" kernel

In "standalone" mode, it is assumed that a custom kernel image is built and used according to http://www.at91.com/linux4sam/bin/view/Linux4SAM/LinuxKernel.<br /><br />During the "Get and patch the Linux kernel", as described in http://www.at91.com/linux4sam/bin/view/Linux4SAM/LinuxKernel, apply the [[%ATTACHURL%/2.6.30-at91-sdio-irq-support.patch][2.6.30-at91-sdio-irq-support.patch]] after applying the 2.6.30-at91-exp.4.tar.gz patchset:
<verbatim>angr@blorg:~$ cd linux-2.6.30
angr@blorg:~/linux-2.6.30$ cp /path/to/2.6.30-at91-sdio-irq-support.patch .
angr@blorg:~/linux-2.6.30$ patch -p1 < 2.6.30-at91-sdio-irq-support.patch</verbatim>

After applying the patch, follow the remaining steps as described in http://www.at91.com/linux4sam/bin/view/Linux4SAM/LinuxKernel to configure, build and install the kernel.<br /><br />See the topic about building the Wi-Fi driver [[BuildDriver]] for information on how to build and install the owl wifi driver kernel module.
