This How-To is meant to be a starting point for people to learn configure mux for IGEP v2 devices as quickly and easily as possible. For this how-to i used [http://releases.linaro.org/platform/linaro-m/headless/final/linaro-m-headless-tar-20101108-2.tar.gz Linaro Headless] and Ubuntu 10.04 with Linaro Toolchain.<br> IgepV2 Board have a default mux configuration, but some cases is necessary change it, for example your project need [[How to set up UART2 in J990|UART2 at j990]] connector to transmit data, for this purpose you need change some mux configurations to enable it and be sure that this modification don't break or interferes in other IC or peripherals. The mux options are vast. There are three ways to configure mux at DM37xx and OMAP35xx:<br>
*Using kernel buddies. This way is ot avaliable in some cases. [[How to set up UART2 in J990#Second_way|Example]].
*Editing and compile kernel sources. [[How to set up UART2 in J990#Third_way|Example]].
 
'''NOTE: before configure mux is necessary review some things:'''
 
 
 
*If connector is shared with other peripherals you should disable it via software or hardware.
*Don't use the same peripheral in more than one pad.
*Omap mux have 8 modes, somes modes are disable in some pads.
