Compile program using your Cross Compiler, I used arm-linux-gnueabi-IGEP SDK: <pre>arm-poky-linux-gnueabi-gcc parse-edid-beta3.c -o parse-edid-beta3</pre> Export binary to IGEP using [[Transfer files via SCP|scp]]: <pre>scp parse-edid-beta3 root@&lt;IGEP IP address&gt;:/home/root </pre>
Run program as root. Pass the i2c number that you want to parse:
<pre>./parse-edid-beta3 -d 23</pre>
