What can I do with IGEP0020

Booting your IGEPv2 board

First of all, you may want to boot your board. IGEP0020 can boot:

• from a MMC/microSD card (first priority in boot order).
• from OneNAND memory.

Using the board LED's

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.

IGEP0020 has 4 LED's which you can control, for example, using 'echo':

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

You can turn them down using the same command and write '0' instead of '1'.
