= Booting your IGEPv2 board<span class="mw-headline" /><br> =
First of all, you may want to boot your board. IGEP0020 can boot:
*from a [[../../../../index.php/How_to_boot_from_MicroSD_Card|MMC/microSD card]] (first priority in boot order).
*from OneNAND memory.
= Using the board LED's<br> =
This is probably the most simple feature in the board, but sometimes LED's may be the only way of checking the status of your applications.<br>
IGEP0020 has 4 LED's which you can control, for example, using 'echo':
<pre>echo 1 > /sys/devices/platform/leds-gpio/leds/d240\:green/brightness
echo 1 > /sys/devices/platform/leds-gpio/leds/d240\:red/brightness
echo 1 > /sys/devices/platform/leds-gpio/leds/d440\:green/brightness
echo 1 > /sys/devices/platform/leds-gpio/leds/d440\:red/brightness
</pre>
You can turn them down using the same command and write '0' instead of '1'.
