*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:

*[[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]].

*Editing and compile kernel sources. [[How to set up UART2 in J990#Third_way|Example]].

*Some peripherals are only available if you place or replace some resistances. See schematics for more information.

*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]] or [[How_to_use_GPIOs|how-to use gpios]] for more information.
