==== DM3730: Decode an WMA audio file (OK)====
  
−
*Power up the modem using the next commands:
+
<pre>bitbake gst-ffmpeg</pre>
−
<pre>echo 0 &gt; /sys/class/gpio/gpio145/value
 
−
echo 1 &gt; /sys/class/gpio/gpio163/value
 
−
sleep 1
 
−
echo 0 &gt; /sys/class/gpio/gpio163/value</pre>  
 
−
*Once the modem is on (led near power button 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>gst-launch -v filesrc location=sample.wma ! asfdemux ! decodebin ! audioconvert ! volume volume=0.25 ! alsasink  </pre>
−
<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>

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.

−
 
−
== Overview  ==
 
−
 
−
This How-To is meant to be a starting point for people to learn use GPIOs for IGEP v2 devices as quickly and easily as possible. For this how-to i used [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]], Ubuntu 10.04 with Linaro Toolchain, IGEP v2 RC5 and [http://downloads.igep.es/labs/gpio-driver.tar.bz2 GPIO driver].
 
−
 
−
There are more ways to use GPIOs in IGEP v2, but this one is very simple.<br>
 
−
 
−
== Feedback and Contributing  ==
 
−
 
−
At any point, if you see a mistake you can contribute to this How-To.<br>
 
−
 
−
== Compile GPIO driver source code via Host<br>  ==
 
−
 
−
Download [http://downloads.igep.es/labs/gpio-driver.tar.bz2 GPIO driver] and [[Linux Kernel 2.6.35.y|Kernel 2.6.35.y]] source code. Extract files.<br>
 
−
 
−
Edit GPIO driver Makefile's:
 
−
 
−
-In files: $/app/Makefile and $/lib/Makefile, make sure that your CROSS_COMPILE path is correct.
 
−
 
−
-In file: $/modules/Makefile, make sure that your CROSS_COMPILE path is correct and&nbsp;type your Kernel 2.6.35.y path.<br>
 
−
 
−
We will use the ncurses program for set up Kernel configuration, if you don't have this program installed then you must install it with this command:
 
−
<pre>sudo apt-get install ncurses-dev
 
−
</pre>
 
−
-Go to kernel path and type:
 
−
<pre>make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- igep00x0_defconfig
 
−
</pre>
 
−
Exit Linux Kernel Configuration an return to Bash. Type:
 
−
<pre>make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- modules_prepare
 
−
</pre>
 
−
File $/include/generated/autoconf.h was created
 
−
 
−
Finally compile GPIO driver, go to main Makefile path and compile all source code using make command.
 
−
 
−
Send binaries created from Host to Igep v2. <br>
 
−

−
Go to:$/modules and insert user-gpio-drv.ko into linux kernel with the following command:
 
−
<pre>insmod user-gpio-drv.ko
 
−
</pre>
 
−
Check that user-gpio-drv.ko is currently loaded with the following command:
 
−
<pre>lsmod</pre>
 
−
The result will be similar at that: <br>
 
−
<pre>root@localhost:~/gpio-driver/module# lsmod

−
The module is loaded until system halt.
 
−
 
−
=== Install shared library  ===
 
−
 
−
Go to:$/lib. libgpio.so is here.
 
−
 
−
If a program is linked with shared libraries, Kernel seek in specific paths when program is executed. Now is necessary link the libgpio.so path to the environment variable LD_LIBRARY_PATH, use the following command:<br>
 
−
<pre>export LD_LIBRARY_PATH=/root/gpio-driver/lib/
 
−
</pre>
 
−
Check that libgpio.so is linked correctly. Go to:$/gpio-driver/app, gpio program is here. Type next command:
 
−
<pre>ldd gpio
 
−
</pre>
 
−
ldd command, print shared library dependencies. The result will be similar at that:
 
−
<pre>root@localhost:~/gpio-driver/app# ldd gpio
 
−
libgpio.so =&gt; /root/gpio-driver/lib/libgpio.so (0x40197000)
 
−
libc.so.6 =&gt; /lib/libc.so.6 (0x401a0000)
 
−
/lib/ld-linux.so.3 (0x4008a000)
 
−
</pre>
 
−
The shared library is linked until system halt. Now you can execute gpio example program.
 
−
 
−
== Testing driver  ==
 
−
 
−
To make sure than driver works well, make the next test. I used GPIO_136(sdmmc2_dat4) and GPIO_137(sdmmc2_dat5) because IGEP v2 RC5(without WIFI) don't use them by default: <br>
 
−
 
−
'''NOTE:''' For more information visit this [[Mux configuration|page]] (under construction). <br>
 
−
 
−
=== Configure Mux  ===
 
−
 
−
Go to:/sys/kernel/debug/omap_mux, and change this mux configuration:
 
−
<pre>echo 0x104&gt;sdmmc2_dat4
 
−
echo 0x104&gt;sdmmc2_dat5
 
−
</pre>
 
−
Use cat command to check it:<br>
 
−
<pre>cat sdmmc2_dat4
 
−
cat sdmmc2_dat5
 
−
</pre>
 
−
The result will be similar at that:
 
−
<pre>root@localhost:/sys/kernel/debug/omap_mux# cat sdmmc2_dat4
 
−
name: sdmmc2_dat4.gpio_136 (0x48002164/0x134 = 0x0104), b ae4, t NA
 
−

−
signals: sdmmc2_dat4 | sdmmc2_dir_dat0 | NA | sdmmc3_dat0 | gpio_136 | NA | NA | safe_mode
 
−
</pre>
 
−
and
 
−
<pre>root@localhost:/sys/kernel/debug/omap_mux# cat sdmmc2_dat5
 
−
name: sdmmc2_dat5.gpio_137 (0x48002166/0x136 = 0x0104), b ah3, t NA
 
−
mode: OMAP_PIN_INPUT | OMAP_MUX_MODE4
 
−
signals: sdmmc2_dat5 | sdmmc2_dir_dat1 | cam_global_reset | sdmmc3_dat1 | gpio_137 | hsusb3_tll_stp | mm3_rxdp | safe_mode
 
−
</pre>
 
−
Note: OMAP_PIN_INPUT=Input/Output pin and OMAP_PIN_OUTPUT=Output pin, for Read/Write test you need the first one. GPIO is configured in mode 4.<br>
 
−
 
−
=== Read/Write test  ===
 
−
 
−
Link GPIO_136 and GPIO_137 with a wire, these pins are located in J990 connector with numbers 7 and 9. I use the next connector to join them:<br>

|}
 
−
 
−
<br>
 
−
 
−
Now type next code:
 
−
<pre>root@localhost:~/gpio-driver/app# ./gpio input 136
 
−
root@localhost:~/gpio-driver/app# ./gpio output 137 0
 
−
root@localhost:~/gpio-driver/app# ./gpio get 136   
 
−
0
 
−
root@localhost:~/gpio-driver/app# ./gpio output 137 1
 
−
root@localhost:~/gpio-driver/app# ./gpio get 136   
 
−
1
 
−
root@localhost:~/gpio-driver/app#
 
−
</pre>
 
−
The results (CMOS Voltages: 0V-1V8):
 
−
 
−

−
 
−
<br> The code above shows that driver works properly, GPIO_136 is configured like input and GPIO_137 is configured like output with value 0, when read GPIO_136 the result is 0. To make sure that works well, configure GPIO_137 with value 1, now GPIO_136 reads 1. <br> This driver have more options like IRQ, but is not explained here.

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)
