=== Is it available s-video or video composite output? ===
IGEP v2 board hasn't s-video or video composite output connector, but there are available on the board some test points to implement a fully-functionaly s-video output.
<br>
=== Which pins are free available on J990 IGEPv2 connector? ===
*IGEP0020-RC1/IGEP0020-RC4 models: You could use McBSP1 pins (12,14,16,18,20,22,24), I2C2 pins (23,24) on J990. You could use software configuration to disable wifi interface and others because of shared wifi hardware lines.
**MMC2 interface is used by wifi of built-in wifi/BT module.
**McBSP3 interface is used by TPS65950 PCM interface and Bluetooth PCM interface of built-in wifi/BT module.
*IGEP0020-RC2 model (no WIFI): these boards are fully functionality compatible to other third boards and all pins are free available (they aren't shared).

=== Is it possible to config the wireless LAN and bluetooth so they are completely off, and not consuming any power at all? ===
Yes, you could use powerdown and reset pins: On [[Frequently Asked Questions and Their Answers#Which_revision_is_my_IGEPv2_board.3F|IGEP0020-RB1/IGEPv2-RB]], wifi powerdown and reset lines are available on GPIO_94 and GPIO_95 pins, and it is not available reset bluetooth line (only TPD06 hardware test point).

For example you can use MAX9213 serializer LVDS to translate the parallel interface to LVDS. <br>
=== Is there a way to attach a VGA monitor directly? ===
=== Is it possible to connect a CMOS sensor (ie are the camera signals available on a board connector)? ===
The camera signals are not available on IGEP v2 IGEPv2 board. <br> <br>
=== Mini usb OTG must be a MINI A Male? ===
Review the Official [http://igep.es/index.php?option=com_content&view=article&id=99&Itemid=129&dir=%2Fvar%2Fwww%2Fvhosts%2Figep.es%2Fhttpdocs%2Fdownloads%2F01-ISEE_Products%2FIGEPv2%2FHW_User_Manuals&download_file=%2Fvar%2Fwww%2Fvhosts%2Figep.es%2Fhttpdocs%2Fdownloads%2F01-ISEE_Products%2FIGEPv2%2FHW_User_Manuals%2FMAN-PR-IGEP.0020-001.23.HW_RC.pdf IGEPv2 Hardware Reference Manual]: Page7: USB 2.0 LS/FS/HS OTG 1 Mini AB USB socket connector (dual slave and host role) – That means you can use MINI-A and MINI-B cable.
<br> === I would like too to know if Is the external wifi antena is antenna easy to install? Where can I acquire a compatible external antenna? ===
On IGEP0020-RB boards: <br>

</pre>
<br>
=== Is it possible to add analog video output? ===
Yes , it is possible. There is no connector for S-video, but signals are available on board test points.
<pre>TP400 and TP401 which are located on bottom side, belongs to luminance and chroma so:
TP401 = TVOUT_1R sch signal = PIN 3 S-video connector = Y = luminance
TP400 = TVOUT_2R sch signal = PIN 4 S-video connector= C = chroma
</pre> <br>
=== Is it possible to power using USB OTG connector? ===
No, it is not possible on IGEPv2 boards. <br>
=== What is the maximun power consumption? ===
The power consumption of IGEPv2@720Mhz is between 750 and 780mA.
=== What about "Skip erase bad block 124 at 0xf80000" means at bootlog? ===
New bad blocks could appear along flash life, and you should mark
them (or JFFS2 file-system does automatically ).
<br>
=== Boot up sequence ===
#Root FS (Network or microSD or Flash or USB or RAMDISK ...)
<br> == IGEP v2 software IGEPv2 Software related questions == === Are the sources for the xloader, uBoot and kernel supplied with IGEPv2 board available? ===
=== How do I stop U-Boot command line at "Hit any key to stop autoboot" prompt ? ===
U-Boot command line is a [[Using serial debug port to communicate|Serial Debug Console|serial tty console]]. IGEPv2 normally uses the UART3to communicate and prompt out. So, you need send any key to <br> Follow this [[Serial Debug ConsoleHow to setup the IDC10 cable|serial porthow to setup the IDC10 cable]] using some serial terminal applicationarticle to connect you Serial cable to your IGEPv2 board. <br>
<br>
Note:Do not press any key of any usb keyboard connected to IGEPv2, as you need to press a key of your computer keyboard in the Serial console, which is attached to [[Using serial debug port to communicate|serial link]] to IGEPv2 via Serial cable.<br> ( minicom, putty or other Serial console running on your computer -> your computer DB9 connector -> Serial cable --> IGEPv2 board ) <br> == IGEPv2 EXPANSION Board Software related questions == === Which x-loader, u---boot and Linux kernel does IGEPv2 EXPANSION board use? === You can download software from the Official [http://git.isee.biz/ GIT repositories] and then you can follow the IGEP0020 steps in [http://labs.igep.es/index.php/The_Linux_kernel| Howto the Linux kernel].<br>----<br><br>== IGEP MODULE Hardware related questions ==
=== Which revision is my IGEP MODULE board? ===

<br> === Which differences are between IGEP MODULE board and IGEPv2 board Board ===T[[:Category:IGEP0020|IGEPv2 Board]] is a start board for testing purposes that you can use for testing the possibilites of the IGEP Platform boards and for developing your own applications.<br> You can also test this technology with the [[:Category:IGEP0022#IGEP0022|IGEPv2 EXPANSION]], which you can instantly attach to the IGEPv2 Board and test even more features and interficies.<br> Once you have tested and checked all the IGEP Platform possibilites you can use the [[:Category:IGEP0030|IGEP COM MODULE]], which consists on a single mini-board with all the IGEPv2 Board capabilities but with just a few of them implemented.BThat means you can create your own expansion board with any peripheral you want and attach it to your product, or you can contact with the [http://www.Diseebcn.com/ ISEE team] (Integration Software Electronic Engineering) where you can ask for a customized board design with your own specifications.<br> <br>
=== Is it possible to power using USB OTG connector? ===
Yes, it is possible to power standalone IGEP MODULE boards (without any baseboard plugged).<br><span style="color: rgb(255, 0, 0);">''' ''Look at''<span style="font-style: italic;">NOTE</span>: DON'T POWER IGEP MODULE through USB OTG and ANY base board AT SAME TIME''' </span>.<br> See also: [[Getting Started with IGEP0030 board|Getting Started with IGEP0030 board]]<br> <br> === What is the maximun power consumption? ===
T.B.D.<br> <br> === I would like too to know if Is the external wifi antena antenna is easy to install? Where can I acquire a compatible external antenna? ===On Default configuration will use the internal shared wifi/BT omni-antenna.<br> But on IGEP-MODULE boardsyou can hardware-hack the board and disconnect the internal antenna to populate U.FL connector for pigtail and external antena:<br>

Check your revision case:<br>
*IGEP MODULE revision D boards do not have the internal antenna populated, but there connector for the external antenna is actually installed.<br>
*IGEP MODULE revision E boards have the internal antenna.<br>
You can get an external antenna at the [https://www.isee.biz/store ISEE online shop].<br>
