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>

= 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:

- • '''MUXMODE ''' (3 bits) defines the multiplexing mode applied to the pin. A mode corresponds to the selection of the functionality mapped on the pin with six (0 to 5) possible functional modes for each pin.

- • '''PULL ''' (2 bits) for combinational pullup/pulldown configuration:

-&gt; PULLTYPESELECT: Pullup/pulldown selection for the pin.

-&gt; PULLUDENABLE: Pullup/pulldown enable for the pin.

- • '''INPUTENABLE ''' (1 bit) drives an input enable signal to the I/O CTRL.  -&gt; INPUTENABLE = 0: Input Disable. Pin is configured in output only mode. - INPUTENABLE = 1: Input Enable. Pin is configured in bidirectional mode.  - Off mode values (5 bits) override the pin state when the OFFENABLE bit CONTROL. This feature is used for power saving management:->OFFENABLE: Off mode pin state override control. Set to 1 to enable the feature and to 0 to disable it.->OFFOUTENABLE: Off mode output enable value. Set to 0 to enable the feature and to 1 to disable it.->OFFOUTVALUE: Off mode output value.->OFFPULLUDENABLE: Off mode pullup/pulldown enable->OFFPULLTYPESELECT: Off mode pullup/pulldown selection <br> <br> <br> '''(more information)'''  <br>  IgepV2 Board have a default mux configuration, but some cases is necessary change it, for example your project need 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.  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> = Feedback and Contributing = At any point, if you see a mistake you can contribute to this How-To.

= Available peripherals on external connector =• '''Off mode values''' (5 bits) override the pin state when the OFFENABLE bit CONTROL. This feature is used for power saving management. Pins in off mode can be configured like output with HIGH or LOW value or input with wake-up detection feature. For input pins, OFFOUTENABLE and OFFOUTVALUE bits can not be configured:

Before configure mux is necessary review some things-&gt;OFFENABLE: Off mode pin state override control. Set to 1 to enable the feature and to 0 to disable it.

- If connector is shared with other peripherals you should disable it via software or hardware&gt;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.

The next tables show you all the mux capabilities-&gt;OFFOUTVALUE: Off mode output value.

=== J990 connector ===-&gt;OFFPULLUDENABLE: Off mode pullup/pulldown enable.

-There are some peripherals than can be connected to J990 like mm3 and camera, but is not used in this how-to&gt;OFFPULLTYPESELECT: Off mode pullup/pulldown selection.

It is controlled by TPS65950, this method avoid reduce Omap proces capabilities. TPS65950 send via I2C1 all the interrupt request. Their characteristics are:<br>  - Can handle up to 8 x 8 keypads, IGEPv2 can handle up to 4 x 4 keypads.<br>- Optionally, you can decode via Omap software.<br>- Event detection on key press and key release.<br>- Multikey press detection, can detect up 2&nbsp; keys at the same time.<br>- Long-key detection on prolonged key press.<br>- Programmable time-out on permanent key press or after keypad release.

More information in TPS65950 datasheetsThis mode is used to disable some pins and reduce power consumption.<br>

=== JC30 connector ===Please contribute.

JC30 is used to connect a camera for capture video or image[http://www. Omap have the processing capability to connect RAW image-sensor modules via this connectorti.com/lit/ug/spruf98x/spruf98x.pdf More information] about mux.

There are some peripherals than can be connected to JC30 like like CAM, SSI and CSI, but is not used in this how-to. GPIO are the default peripheral.<br> = Configure Mux =

Mux options are vast, at the beginning can be difficult and tedious change some configurations. Before configure mux, use this connector be careful at these pointsthe following tips to avoid problems:

- Pad 1 *Mux can be used to power down wifi module if RD41 is short circuitconnect multiple connectors at the same peripheral, replace RD42 for this porpouseimproper use can damage the processor.<br>- Pad 2 can be Before configure mux, revise that this peripheral is not used to reset wifi module in other pads. See schematics or [[Connectors Summary|connectors summary]] for more information. *Some peripherals are only available if RD43 is short circuit, you place or replace RD44 some resistances. See schematics for this porpousemore information.<br>- Pad 21 can be connected to I2C2_SCL*Some connectors share multiples peripherals like OMAP, WIFI/BT combo, that wire is shared with J990 connector and I2C2_SCL peripheraletc. Placing/replacing RC13 for tis porpouseYou should disable unused peripherals to avoid interferences.<br>- Pad 22 can be connected &nbsp; For example: if you want to control WIFI module via J990 disable OMAP or if you want use [[How to I2C2_SDA, that wire is shared with set up UART2 in J990 connector and I2C2_SDA peripheral|UART2 at j990]] disable Bluetooth.

<br> '''(6):''' TFP410: Converts DVI&nbsp;signal to HDMI. They share the same video signal.<br> === IGEP MODULE ===

=== JA41 Next table pretends help you to configure IGEP MODULE. First column shows some OMAP35xx/DM37xx peripherals and first row shows all IGEP MODULE connectors. Read articles about connector ===and peripheral before use them. Each configuration can take different solutions. <br> There are some connectors than have more peripherals available, but they don't have all signals to use it. <br> Table shows four answers:&nbsp;

JA41 *"'''Yes, default configuration(utility)'''": Peripheral enabled by default. "utility" shows if this peripheral is used for DVI .<br> *"'''Yes, not default configuration(information)'''": Peripheral don't enabled by default. Maybe you need to disable other one<br> *"'''No, via hardware'''": Not available, but via hardware (Digital Video Interfaceplacing or replacing some resistances) data partcan be enabled.<br> *"'''No'''"

-There are some peripherals than can be connected to JA41 like DSSVENC, HW, DSS and SDI, but is not used in this how-to.  Some pads have mux capabilities:  {| cellspacing="1" cellpadding="1" border="1" align="JUSTIFY" style="width: 669px933px; height: 1064px190px;"
