This wiki page has more detailed information about muxon IGEPv2. <br> Read general [[Mux configuration|this 'Mux configuration' page]] before use it. This article contains: <br>
*How-to disable some external peripherals to avoid interferences
*Some detailed examples.
'''Compile kernel source code'''
Use this [[Linux Kernel 2.6.35.y|tutorial]] (Kernel) and this [http://labs.igep.es/index.php/The_IGEP_X-loader other] (IGEPxloader) to install Linaro Headless (or Poky) with your custom kernel in SD card. You can compile the IGEPxloader, but is not necessary.<br>

=== UART3 in J960 ===
Edit igep.ini to disable serial debug, comment next linelines:
<pre>; Setup the Kernel console params
;console=ttyO2,115200n8;console=ttyS2,115200n8 ; Enable early printk;earlyprintk=serial,tty02,115200;earlyprintk=serial,ttyS2,115200 </pre> Poky linux starts an user terminal at UART3, You must disable it to avoid interferences. Comment next lines in /etc/inittab: <pre># Normally not reached, but fallthrough in case of emergency.#z6:6:respawn:/sbin/sulogin#S:2345:respawn:/sbin/getty 115200 ttyO2# /sbin/getty invocations for the runlevels.</pre> You can test new configuration using [[How to use UARTs|this tutorial]]<br>
=== GPIO in J990 ===
