Install Linaro Distribution

Please follow the next howto.

Linaro wifi kernel support

You can download the kernel images release 2.6.35-1010.17 with wifi support from our website:

  1. Kernel link.
  2. Kernel headers.

Just download on the freshly booted board. You can install them on the board as follows: 

sudo apt-get install linux-headers-2.6.35-1010
sudo dpkg -i linux-image-2.6.35-1010-linaro-omap_2.6.35-1010.17_armel.deb
sudo dpkg -i linux-headers-2.6.35-1010-linaro-omap_2.6.35-1010.17_armel.deb

SGX Acceleration [EXPERIMENTAL!]

This worked for me, no idea if it works for anyone!

1. Install the linux kernel headers for the linaro version that is running on your board in my case 

sudo apt-get install linux-headers-2.6.35-1008-linaro-omap

2. Get the openGL backend: 

sudo apt-get install libegl1-sgx-omap3 libgles1-sgx-omap3 libgles2-sgx-omap3

Now you can run the demos that are mentioned in the Ubuntu guide. Have fun emoticon.
