*Power up IGEPv2 *Open PuTTy. *Choose Serial line. If you are running PuTTy on Windows, the Serial line will be like (COM1 or COM2 or COM3, etc.). If you are running PuTTy on Ubuntu, the Serial line will be like (/dev/ttyS0 or /dev/ttyS1 or /dev/ttyS3, etc.). Note that if you are using a USB->Serial converter, the Serial line will be like /dev/ttyUSB0 *Configure Speed to 115200 *Select Serial Connection type *Press on Open button *You will successfully started the console board.ei485=no
<br> You need a Null-Modem DB9 male-make serial cable. Connect the cable between the target board and your PC.

Seiko and Powertip touch screens are not supported by default Now when you write a character in IGEPv2you PC serial port, the character should appear in the target board. 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 A detailed guide on how use UARTS can be found by following commandsthis link:<pre>ssh root@192.168.5.1 mkdir /tmp/tempmount -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 [[How to finish it.<br>use UARTs]]
'''Basic''' IGEPv2 Expansion integrates a GSM/GPRS modem to make phone calls or to send SMS or to write and read data from it, etc. Telit modem is not supported by default in IGEPv2 Expansion. Configure this [[How_do_I_edit_my_kernel_command_line | adding following kernel cmdline parameter]]
Telit buddy.modem is not supported by default in IGEPv2. Use the following steps for it: =yes
buddy.modem=yes *Save changes (ESC -> :wq -> Enter) and reboot your IGEP Device *Power up the modem using the next commands:<pre>echo 0 > /sys/class/gpio/gpio140/valueecho 1 > /sys/class/gpio/gpio141/valuesleep 1echo 0 > /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>
If you successfully '''followed the previous instructions''', you are ready to test the GSM/GPRS modem{| cellspacing="1" cellpadding="1" border="1" width="200"|-| [[Image:Igepv2expgstreamercapture. Here are some examples: jpg|400px]]|}
You can check the complete list of AT commands at the Official manufacturer ''From [http://telit.com/module/infopool/download.php?id=522 Software User Guide[How to setup tvp5151 video decoder]]. ''
Use The following example writes the instructionvalue 0x22 to register 0x10 of device 0x50 on i2c bus 2: <pre>at+csq$ i2cset -f -y 2 0x50 0x10 0x22$ i2cget -f -y 2 0x50 0x10</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 ''From [[How to use an antenna<br> EEPROM]]''
Use the instruction, replace number_to_call with your number[[Image: <pre>atd number_to_call</pre> Press Igepv2expcanconnector.PNG|right|200px]]IGEPv2 Expansion integrates a CAN peripheral. Connect any key CAN bus device or network to end call the CAN bus connector (J703).
'''NOTEYou have to connect the two boards like this:''' If "NO CARRIER" message appears, check your coverage or use an antenna. <br>

== How to use Serial communication (DB9 connector) TFT and Touchscreen ==[[Image:IGEP0022 PROTO RA DSC 0142.JPG|right|200px]] IGEPv2 Expansion supports SEIKO 7” or POWERTIP 4.3” LCD screen. Use J301 connector for POWERTRIP 4.3" or use J302, J303 and J304 connector for SEIKO 7".<br> Seiko and Powertip touch screens are not supported by default in IGEPv2. Use the following steps for it:
== How to use serial console ==[[Image:Igepv2expdb9connector.PNG|right|200px]] IGEPv2 Expansion integrates a DB9 RS232 link connector. This UART is shared with RS485 so it's incompatible use both interfaces at the same time. For that reason to use UART1 for UART 3 (/dev/ttyO2) can be obtained through J502 DB9 connectorRS232 comunications you should disable RS485 interface. You can use PuTTy to get a shell prompt to IGEP: do this [[How_do_I_edit_my_kernel_command_line | adding following kernel cmdline parameter]].

*Log into IGEPv2 (via SSH, [http://labs.isee.biz/index.php/Getting_started_with_IGEPv2#Log_into_IGEPv2_via_Ethernet_interface as shown in Power up the previous chapter]), and run modem using the following next commands:<pre>ssh root@192.168.5.1 mkdir $ echo 0 > /sys/class/gpio/tmpgpio140/tempvaluemount -t jffs2 $ echo 1 > /sys/devclass/mtdblock1 gpio/tmpgpio141/temp value$ sleep 1vi $ echo 0 > /sys/class/tmpgpio/tempgpio141/igep.ini value</pre> *Add Once the following line modem is on (press i to insert contentled near power button is blinking now):, you can interact with it via UART 2.
*To check the modem status use the command:<br>
<pre>at</pre>
*If you correctly inserted the PIN number, the answer should be OK. 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>
