= Overview =
This wiki is meant to be a starting point for people to learn configure mux for IGEP devices as quickly and easily as possible. This wiki contains:<br>
*Mux characteristics summary
*Tips to avoid problems
*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>
= Introduction =
Mux (or multiplexer) is a Omap peripheral that can be controlled via software. Its function is connect other peripherals to some available Omap pins.
The functional bits of a pad configuration register field are divided into the following five fields:
-> PULLTYPESELECT: Pullup/pulldown selection for the pin.
-> PULLUDENABLE: Pullup/pulldown enable for the pin.
- If connector is shared with other peripherals you should disable it via software or hardware>OFFOUTENABLE: Off mode output enable value.<br> - Don't use Set to 0 to enable the same peripheral in more than one pad.<br> - Omap mux have 8 modes, somes modes are feature and to 1 to disable in some padsit.
-There are some peripherals than can be connected to J990 like mm3 and camera, but is not used in this how-to>OFFPULLTYPESELECT: Off mode pullup/pulldown selection.
