Unable to access router through LAN port in BPI R2-Pro

Recently I have build image for BPI-R2 Pro from source code given by BPI-SINOVOIP which is mentioned on webpage of the BPI-R2 Pro but I am unable to access my router from LAN port after flashing that image on router even I have tried by changing multiple IP it is not accessible.

Why this problem occurs ? is there any other way to access my router.
