Thanks for the Lead . This is eventually for the company but currently I am getting into embedded Linux , So not a problem to change over to another board like 9260 as you suggested .I will be carrying out the development on a Linux machine .
I have been using Skyeye for a while and actually ported a RTOS ( FreeRTOS ) on a Samsung ARM7T simulator . But Linux is very different :( . Thanks for the support .
