<br> One pad configuration register field is available for each pin. Each 32-bit pad configuration register is grouped into two 16-bit pad configuration register fields. One pad configuration register provides control for two different pins. These registers can be accessed using 8, 16 There are three ways to configure mux in IGEP Boards based in OMAP35xx and 32 bits operations.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.

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. = Introduction =
This How-To Mux (or multiplexer) is meant to a Omap peripheral that can be a starting point for people to learn configure mux for IGEP v2 devices as quickly and easily as possiblecontrolled via software. For this how-Its function is connect other peripherals 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 Toolchainsome available Omap pins.<br>
= Feedback and Contributing =Each pin is configurable by software using its associated pad configuration register field, which is 16 bits wide:
At any point, if you see a mistake you can contribute to this How-To.  = Available peripherals on external connector = Before configure mux is necessary review some things:  - If connector is shared with other peripherals you should disable it via software or hardware.<br> - Don't use the same peripheral in more than one pad.<br> - Omap mux have 8 modes, somes modes are disable in some pads.  The next tables show you all the mux capabilities:  === 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"

'''(Mode 1):to mode 6''' To protect Omap pads from external signalsare possible modes for alternate functions. On each pin, some modes are used effectively for alternate functions, configure Mux in mode=7 (safe_mode)while other modes are unused and correspond to no functional configuration. With this mode, buffer is configured in high impedance
'''The safe mode (2default mode 7):''' Disable TPS65950 go avoids any risk of electrical contention by configuring the pin as an input with no functional interface mapped to file sound/soc/codecs/twl4030it. The safe mode is used mainly as the default mode for all pins containing no mandatory interface at the release of power-on reset.c change line 54 Code: <pre>0x00, /* REG_VOICE_IF (0xF) */</pre> to Code: <pre>0x04, /* REG_VOICE_IF (0xF) */</prebr>

=== J970 connector ===Mux options are vast, at the beginning can be difficult and tedious change some configurations. Before configure mux, use the following tips to avoid problems:
This connector don't have *Mux can connect multiple connectors at the same peripheral, this improper use can damage the processor. Before configure mux capabilities, 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.
J970 is used to implement a keypad. It is controlled by TPS65950, this method avoid reduce Omap proces capabilities. TPS65950 send via I2C1 all the interrupt request. Their characteristics are:<br> === IGEPv2 ===

=== JC30 connector === 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 connector.  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>  Before use this connector be careful at these points:  - Pad 1 can be used to power down wifi module if RD41 is short circuit, replace RD42 for this porpouse.<br>- Pad 2 can be used to reset wifi module if RD43 is short circuit, replace RD44 for this porpouse.<br>- Pad 21 can be connected to I2C2_SCL, that wire is shared with J990 connector and I2C2_SCL peripheral. Placing/replacing RC13 for tis porpouse.<br>- Pad 22 can be connected to I2C2_SDA, that wire is shared with J990 connector and I2C2_SDA peripheral. Placing/replacing RC14 for tis porpouse.  === JA42 connector === JA42 is used for DVI (Digital Video Interface) control part, TouchScreen control and SPI1.<br>  -There are some peripherals than can be connected to JA42 like MM3, MM2, SSI, USB and HW_DBG, but is not used in this how-to.  Some pads have mux capabilities:  {| cellspacing="1" cellpadding="1" border="1" align="JUSTIFY" style="width: 804px933px; height: 343px409px;"

<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 part.<br>
-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 than can be connected to JA41 like DSSVENC, HW, DSS and SDIavailable, 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. "utility" shows if this peripheral is used.<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 (placing or replacing some resistances) can be enabled.<br> *"'''No'''"
