This How-To is meant to be a starting point for people to learn use UART for IGEPv2 devices as quickly and easily as possible. In this how-to, we use [http://releases.linaro.org/platform/linaro-m/headless/final/linaro-m-headless-tar-20101108-2.tar.gz Linaro Headless] with [[Linux Kernel 2.6.35.y|Kernel 2.6.35.y]] and [http://labs.isee.biz/images/e/ee/Uart-test-beta2.tar.bz2 UART test program]

Program sends information via UART1 but don't receive response via UART3, because only a process is executed. This problem is repeated every 5 seconds (constant WAIT=5) until other process sends information via UART3 at the same speed. If "select" hasn't been implemented, process would have stayed blocked.<br>

'''under construction'''
  
−
This program have three I/O functions that connect to UART driver via ioctl: (read(), write() and select()). But select() and write() change process stat to sleep mode until system don't receive or transmit all information via UART. "select" function is used to prevent that read function can be blocked when data aren't available. <br>The next images (program with debug_gpio enabled and 300 bauds speed) show when process is executed or is waiting. Blue=UART1, Violet="write" and Green="select". When GPIO has HIGH value, process is blocked.<br>

Seiko a Powertip touch screens are not supported by default in IGEPv2. Use the following steps for it:
 
−
 
 
−
*Log into IGEPv2 (via SSH, [http://labs.isee.biz/index.php/Getting_started_with_IGEPv2#Log_into_IGEPv2_via_Ethernet_interface as shown in the previous chapter]), and run the following commands:
 
−
<pre>ssh root@192.168.5.1
 
−
mkdir /tmp/temp
 
−
mount -t jffs2 /dev/mtdblock1 /tmp/temp
 
−
vi /tmp/temp/igep.ini </pre>
 
−
*In Seiko screen add the following line:
 
−
<pre>omapdss.def_disp=lcd-70</pre>
 
−
*In Powertip screen add the following line:
 
−
<pre>omapdss.def_disp=lcd-43</pre>
 
−
*Save changes and reboot your IGEP Device to finish it.<br>

== How to use Telit Modem  ==
 
−
 
 
−
'''Basic'''
 
−
 
 
−
Telit modem is not supported by default in IGEPv2. Use the following steps for it:
 
−
 
 
−
*Log into IGEPv2 (via SSH, [http://labs.isee.biz/index.php/Getting_started_with_IGEPv2#Log_into_IGEPv2_via_Ethernet_interface as shown in the previous chapter]), and run the following commands:
 
−
<pre>ssh root@192.168.5.1
 
−
mkdir /tmp/temp
 
−
mount -t jffs2 /dev/mtdblock1 /tmp/temp
 
−
vi /tmp/temp/igep.ini </pre>
 
−
*Add the following line (press i to insert content):
 
−
 
 
−
buddy.modem=yes
 
−
 
 
−
*Save changes (ESC -&gt;&nbsp;:wq -&gt; Enter) and reboot your IGEP Device
 
−
*Power up the modem. You can power off using again these commands:
 
−
<pre>echo 0 &gt; /sys/class/gpio/gpio140/value
 
−
echo 1 &gt; /sys/class/gpio/gpio141/value
 
−
sleep 1
 
−
echo 0 &gt; /sys/class/gpio/gpio141/value
 
−
</pre>
 
−
*Once the modem is on (led D401, near SIM card reader, is blinking now), you can interact with it via UART 2. You can use Microcom to comunicate with it from the serial debug console:
 
−
<pre>microcom -s 115200 /dev/ttyO1</pre>
 
−
*To check the modem status use the command:<br>
 
−
<pre>at</pre>
 
−
*Answer should be OK.<br>  
 
−
*Now unlock it by inserting your SIM card PIN number. Use the command:
 
−
<pre>at+cpin=&lt;PIN&gt;</pre>
 
−
*If you correctly inserted the PIN number, the answer should be OK.&nbsp;If you fail more than 3 times, your SIM card will lock and you will have to insert PUK number.
 
−
*Now you are ready to use the GSM/GPS modem.<br>
 
−
 
 
−
=== Examples  ===
 
−
 
 
−
If you successfully '''followed the the previous instructions''', you are ready to test the GSM/GPRS modem. Here are some examples:
 
−
 
 
−
You can check the complete list of AT commands at the Official manufacturer [http://telit.com/module/infopool/download.php?id=522 Software User Guide].
 
−
 
 
−
==== Test received signal strength<br>  ====
 
−
 
 
−
Use the instruction:
 
−
<pre>at+csq</pre>
 
−
The answer should be: +CSQ: X,0, where X is the signal strenght. For example 12 is poor and 18 is good. If the answer is +CSQ:99,99 you should check your coverage or use an antenna<br>
 
−
 
 
−
==== Making a phone call<br>  ====
 
−
 
 
−
Use the instruction, replace number_to_call with your number:
 
−
<pre>atd number_to_call
 
−
</pre>
 
−
Press any key to end call
 
−
 
 
−
'''NOTE:''' If "NO CARRIER" message appears, check your coverage or use an antenna.
 
−
 
 
−
==== Sending a SMS<br>  ====
 
−
 
 
−
First of all, you need to configure the SMS format type. Telit GE865 GSM/GPRS supports PDU format and Text format. We use Text format. Type the following command:
 
−
<pre>AT+CMGF=1</pre>
 
−
There are so many ways in this modem to send a message. Here you have a simple example. Use the instruction, replace destination_number with your number:
 
−
<pre>at+cmgs= destination_number
 
−
&gt; insert here your text message
 
−
</pre>
 
−
When you are ready to send your message use Ctrl+Z to send it.
 
−
 
 
−
If you want to cancel or restart the message press ESC.<br>
 
−
 
 
−
'''NOTE:''' If "NO CARRIER" message appears, check your coverage or use an antenna.
 
−
 
 
−
'''NOTE:''' Don't use special characters in SMS text message like &lt;`´'"&gt;.<br>

−
<pre>ssh root@192.168.5.1
 
−
</pre>
 
−
*Now you have a remote igep terminal<br>  
 
−
*Refresh repositories and accept it.
 
−
<pre>zypper ref </pre>
 
−
*Install video4linux2 plugin
 
−
<pre>zypper in gst-plugins-good-video4linux2
 
−
</pre>
 
−
*Load OMAP ISP kernel module<br>
 
−
<pre>modprobe omap3-isp
 
−
</pre>
 
−
*Configure ISP, for PAL resulution use 720x576 for NTSC resolution use 720x480:<br>
 
−
<pre>media-ctl -r -l '"tvp5150 2-005c":0-&gt;"OMAP3 ISP CCDC":0[1], "OMAP3 ISP CCDC":1-&gt;"OMAP3 ISP CCDC output":0[1]'
 
−
media-ctl -v --set-format '"tvp5150 2-005c":0 [UYVY 720x480]'
 
−
media-ctl -v --set-format '"OMAP3 ISP CCDC":0 [UYVY 720x480]'
 
−
media-ctl -v --set-format '"OMAP3 ISP CCDC":1 [UYVY 720x480]' </pre>
 
−
*Export display
 
−
<pre>export DISPLAY=:0.0 </pre>
 
−
*Launch gstreamer
 
−
<pre>gst-launch-0.10 -v v4l2src device=/dev/video2 queue-size=8&nbsp;! video/x-raw-yuv,format=\(fourcc\)UYVY,width=720,height=480&nbsp;! ffmpegcolorspace&nbsp;! autovideosink</pre>

== How to use EEPROM  ==
 
−
 
−
'''Basic'''
 
−
 
−
The IGEP0022 expansion board provides an AT24C01B serial EEPROM memory which is connected to the OMAP via I2C (register 50).<br>
 
−
 
−
Use i2c-tools to manage it:
 
−
<pre>i2cget &lt;bus&gt; &lt;chip&gt; &lt;register&gt;
 
−
i2cset &lt;bus&gt; &lt;chip&gt; &lt;register&gt; &lt;value&gt;</pre>
 
−
For example, the following writes the value 0x22 to register 0x10 of device 0x50 on i2c bus 2:
 
−
<pre>i2cset -f -y 2 0x50 0x10 0x22
 
−
i2cget -f -y 2 0x50 0x10</pre>

BASE0033 CONNECTOR SUMMARY TABLE

Configure a static IP using the same private network range

under construction

IGEP Firmware Yocto uses the following Ethernet network configuration (IP addresses)

  • eth0 − 192.168.5.1
  • eth0:0 − assigned via dhcp.

This Ethernet network configuration is really useful when you work using a Linux operating system like IGEP SDK Virtual Machine. Because you use eth0 device to communicate easily with your board and eth0:0 device to get Internet acces using dhcp protocol.

But some scenarios this network configuration is not useful, for example: if you use a non-Linux operating system, connect to two IP private range interfaces is not simple. This How-to can be useful to

(Make diagram one: IGEP and Linux defualt communication. Diagram 2 IGEP and other SO alternative configuration)
