Mux (or multiplexer) This wiki is meant to be a Omap peripheral that can be controlled via software. Its function is connect other peripherals starting point for people to some available Omap padslearn configure mux for IGEP devices as quickly and easily as possible. This wiki contains:<br>

IgepV2 Board have a default mux configuration, but some cases is necessary change it, for example your project need UART2 at j990 connector *Mux characteristics summary*Tips to avoid problems*Ways to transmit data, for this purpose you need change some configure mux configurations to enable it and be sure *Tables that this modification don't break or interferes in other IC or links peripherals. The mux options are vast. and connectors for IGEPv2 and IGEP MODULE

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 There are three ways to configure mux in IGEP Boards based in OMAP35xx and Contributing =DM37xx:<br>

At any point*[[Mux_instructions|Configuring MUX from OS User Space]]. This mode has a issue, if when your system reboot or shutdown you see a mistake you can contribute 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 this 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-Toto set up UART2 in J990#Third_way|Example]]. <br>

= Available peripherals on external connector =

Before configure mux is necessary review some things: = Introduction =

- If connector Mux (or multiplexer) is shared with other peripherals you should disable it a Omap peripheral that can be controlled via software or hardware.<br> - Don't use the same peripheral in more than one pad.<br> - Its function is connect other peripherals to some available Omap mux have 8 modes, somes modes are disable in some padspins.

The next tables show you all the mux capabilitiesEach pin is configurable by software using its associated pad configuration register field, which is 16 bits wide:

=== J990 connector === -There are some peripherals than can be connected to J990 like mm3 and camera, but is not used in this how-to.  -High Speed USB 3 is only available on Omap 3530 in the next pads:  &nbsp;&nbsp;&nbsp;&nbsp; 3: HSUSB3_TLL_NXT<br> &nbsp;&nbsp;&nbsp;&nbsp; 4: HSUSB3_TLL_D4<br> &nbsp;&nbsp;&nbsp;&nbsp; 5: HSUSB3_TLL_DIR <br> &nbsp;&nbsp;&nbsp;&nbsp; 6: HSUSB3_TLL_D6<br> &nbsp;&nbsp;&nbsp;&nbsp; 7: HSUSB3_TLL_STP<br> &nbsp;&nbsp;&nbsp;&nbsp; 8: HSUSB3_TLL_D7 <br> &nbsp;&nbsp;&nbsp;&nbsp; 10: HSUSB3_TLL_D5  <br>  {| cellspacing="1" cellpadding="1" border="1" align="JUSTIFY" style="width: 960px; height: 1463px;center"

This connector don't have mux capabilities. === Input Enable ===

J970 is used to implement a keypadINPUTENABLE = 0: Input Disable. It Pin is controlled by TPS65950, this method avoid reduce Omap proces capabilities. TPS65950 send via I2C1 all the interrupt requestconfigured in output only mode. Their characteristics are:<br>

- Can handle up to 8 x 8 keypads, IGEPv2 can handle up to 4 x 4 keypadsINPUTENABLE = 1: Input Enable.<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 pressPin is configured in bidirectional mode.<br>- Programmable time-out on permanent key press or after keypad release.

More information in TPS65950 datasheets.<br> === '''Off mode values''' and '''Wake-up''' ===

=== JC30 connector ===This mode is used to disable some pins and reduce power consumption. <br>

JC30 is used to connect a camera for capture video or image. Omap have the processing capability to connect RAW image-sensor modules via this connectorPlease contribute.

There are some peripherals than can be connected to JC30 like like CAM, SSI and CSI, but is not used in this how-to[http://www. GPIO are the default peripheralti.com/lit/ug/spruf98x/spruf98x.pdf More information] about mux.<br>

Before use this connector be careful at these points: = Configure Mux =

- Pad 1 can be used to power down wifi module if RD41 is short circuitMux options are vast, replace RD42 for this porpouse.<br>- Pad 2 at the beginning can be used to reset wifi module if RD43 is short circuit, replace RD44 for this porpousedifficult and tedious change some configurations.<br>- Pad 21 can be connected to I2C2_SCLBefore configure mux, that wire is shared with J990 connector and I2C2_SCL peripheral. Placing/replacing RC13 for tis porpouse.<br>- Pad 22 can be connected use the following tips to I2C2_SDA, that wire is shared with J990 connector and I2C2_SDA peripheral. Placing/replacing RC14 for tis porpouse. avoid problems:

=== JA42 connector ===*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.&nbsp; 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.

JA42 is used for DVI (Digital Video Interface) control part, TouchScreen control and SPI1.<br> === IGEPv2 ===

-Next table pretends help you to configure IGEPv2. First column shows some OMAP35xx/DM37xx peripherals and first row shows all IGEPv2 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 than can be connected to JA42 like MM3, MM2, SSI, USB and HW_DBGavailable, but is not used in this how-they don't have all signals touse it. <br> Table shows four answers:&nbsp;

Some pads have mux capabilities*"'''Yes, default configuration(utility)'''": Peripheral enabled by default.

<br> '''(6):''' TFP410: Converts DVI&nbsp;signal to HDMI. They share the same video signal.<br>  === JA41 connector IGEP MODULE ===

JA41 is used for DVI (Digital Video Interface) data partNext 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;

-There are some peripherals than can be connected *"'''Yes, default configuration(utility)'''": Peripheral enabled by default. "utility" shows if this peripheral is used.<br> *"'''Yes, not default configuration(information)'''": Peripheral don't enabled by default. Maybe you need to JA41 like DSSVENCdisable other one<br> *"'''No, HW, DSS and SDIvia hardware'''": Not available, but is not used in this how-tovia hardware (placing or replacing some resistances) can be enabled. <br> *"'''No'''"
