*Ways to configure mux
*Tables that links peripherals and connectors for IGEPv2 and IGEP MODULE
There are three ways to configure mux in IGEP Boards based in OMAP35xx and DM37xx:<br>
*[[Mux_instructions|Configuring MUX from OS User Space]]. This mode has a issue, when your system reboot or shutdown you will need to configure again. [[How to set up UART2 in J990#First_way|Example]].
*Configuring MUX by using kernel commandline buddies. This way is not avaliable in some cases. [[How to set up UART2 in J990#Second_way|Example]] and [[Linux Kernel 2.6.37.y#Kernel_Parameters|buddies parametres]].<br>
*Editing and compile kernel sources. [[How to set up UART2 in J990#Third_way|Example]].<br>

*Mux can connect multiple connectors at the same peripheral, this improper use can damage the processor. Before configure mux, revise that this peripheral is not used in other pads. See schematics or [[Connectors Summary|connectors summary]] for more information.
*Some peripherals are only available if you place or replace some resistances. See schematics for more information.<br>
*Some connectors share multiples peripherals like OMAP, WIFI/BT combo, etc. You should disable unused peripherals to avoid interferences. For example: if you want to control WIFI module via J990 disable OMAP or if you want use [[How to set up UART2 in J990|UART2 at j990]] disable Bluetooth. See schematics, of board or [[Connectors Summary|connectors summary]] or [[Mux_instructions#Disable_Peripherals|how-to disable peripherals]] for more information.
