=== Is it possible to connect a battery to maintain the real time clock in the board? ===
Battery backup is not implemented on IGEPv2-RA and IGEPv2-RB.
User You can use i2c external rtc or connect externally a super-cap/rechargable battery on R768 pins.
R768 is 0 Ohm resistor connected between GND and BKBAT (M14) input from TPS65950.
IGEPv2-RC has available an unpopulated a super-cap/rechargable battery footprint (BT741) for real time clock backup batterybatter.  <br>

=== How many UARTs are available? ===
OMAP3 OMAP3530 has 3 UARTS:
<pre>UART1 --&gt; RS485 on connector J940
UART2 --&gt; bluetooth
UART3 --&gt; debug console on connector J960
</pre>
OMAP3730 has 4 UARTS:<br>

UART2 --&gt; bluetooth
UART3 --&gt; debug console on connector J960
UART4 --&gt; (NOT&nbsp;AVALIABLE on IGEPv2: it uses GPMC_WAIT2 and GPMC_WAIT3 pins)
</pre>
All of this UART are also available on other connectors:
UART3 --&gt; on connector JA41 without DVI transceiver with CMOS 1v8 logic.
</pre>
Read this How to use [[Using serial debug port to communicate|debug serial port]].
 
<br>
 
=== 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&nbsp; 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).

=== 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 ...).

=== 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).
'''<br>'''
We change The GPIO_94/GPIO_95 of IGEP0020-RB1 version is changed to GPIO_138/GPIO_139 of IGEP0020-RCx version because GPIO_94/GPIO_95 are camera interface lines.<br>

=== Could you attach an LCD with LDVS interface? ===<br>
=== Can I attach an LCD with LDVS interface? === You have to translate or convert 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.  <br>
=== Is there a way to attach a VGA monitor directly? ===
You IGEPv2 does not has VGA output. But you can use :<br>  *a DVI to VGA converter connected to the IGEPv2 DVI output. *an [[Which IGEP board do I have#IGEP0022|IGEPv2 expansion board]], which expands IGEPv2 board capabilities. Among other things provides the VGA&nbsp;interface on D-SUB15 connector.<br> <br>
=== 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? ===

A popular Hirose U.FL (MHF IPEX) connector to SMA-RP (reverse polarity) connector cable fits in
<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.
IGEP v2 IGEPv2@720MHz has aprox. 15% more power consumption on core and mpu_iva than at 600MHZ.  <br>
=== 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 ).
