= Frequently Asked Questions and Their Answers = == ISEE/IGEP Common Questions ===== Which IGEP board do I have ? ===If you read silkscreen...* "IGEP0020-...": You have an IGEPv2 board ([[Frequently_Asked_Questions_and_Their_Answers#Which_revision_is_my_IGEPv2_board.3F | See IGEPv2 version details]]). == IGEP v1 hardware related questions == == IGEP v1 software related questions ==
== IGEP v2 hardware related questions ==
=== Is it possible to connect a battery to maintain the real time clock in the board? ===
Battery backup is not implemented on IGEP v2 RA and RB.
R768 is 0 Ohm resistor connected between GND and BKBAT (M14) input from TPS65950.
=== How is it connected Bluetooth chipset to OMAP ? ===
UART2.
UART3 --> on connector JA41 without DVI transceiver with CMOS 1v8 logic.
</pre>
=== Is it available s-video or video composite output? ===
You have to translate it to LVDS which is a differential and serialized interface. For example you can use MAX9213 serializer LVDS to translate the parallel interface to LVDS.
=== Is there a way to attach a VGA monitor directly? ===
You can use DVI to VGA converter connected to DVI output.
=== I would like too to know if the external wifi antena is easy to install? Where can I acquire a compatible external antenna? ===
On IGEP0020-RB boards: <br>
<pre>The JD11 is a GSC connector for the external Wifi interface. It is a MURATA GSC connector, Part number MM9329-2700RA1.
You only have to find a cable that fits with this MURATA connector.
Regarding the antenna, just need a 2.4Ghz Antenna. </pre>On IGEP0020-RC boards: <br>
<pre>The JD11 is a "HRS (HIROSE) - U.FL-R-SMT(01) - RECEPTACLE, SMT, U.FL " connector
A popular Hirose U.FL (MHF IPEX) connector to SMA-RP (reverse polarity) connector cable fits in
</pre>On IGEP-MODULE boards:<br>
<pre>The J2 is a "HRS (HIROSE) - U.FL-R-SMT(01) - RECEPTACLE, SMT, U.FL " connector
A popular Hirose U.FL (MHF IPEX) connector to SMA-RP (reverse polarity) connector cable fits in
</pre><br>
=== Is it possible to add analog video output? ===
TP400 = TVOUT_2R sch signal = PIN 4 S-video connector= C = chroma
</pre>
=== Which revision is my IGEPv2 board? ===
=== Is it possible to power using USB OTG connector? ===
=== What is the max Ethernet throughput with LAN9221i? ===
The [http://en.wikipedia.org/wiki/Ethernet ethernet] throughput it's 94-96 M/bits second, [http://www.smsc.com/index.php?tid=145&pid=116 LAN9221i] it's connected direcly to OMAP processor addressable space and dedicated IRQ (no USB, SPI, converters ...).
<pre># iperf -c 192.168.3.2

== IGEP v2 software related questions ==
=== Are the sources for the xloader, uBoot and kernel supplied with the IGEPv2 board available? ===
All of them are available on [http://git.igep.es git.igep.es] if you are a registered user.
=== How do I stop U-Boot command line at "Hit any key to stop autoboot" prompt ? ===
U-Boot command line is a [[Serial_Debug_ConsoleSerial Debug Console|serial tty console]]. IGEPv2 normally uses UART3. So, you need send any key to [[Serial_Debug_ConsoleSerial Debug Console|serial port]] using some serial terminal application.
'''Look up! ''' Don't press any key of any usb keyboard connected to IGEPv2, you need press any key of your computer keyboard attached to [[Serial_Debug_ConsoleSerial Debug Console|serial link]] to IGEPv2 ( serial cable + minicom or other serial terminal application )
