Hi All,
thanx all for ur kind help...the problem was neither due to Memory Mapping nor CRC check... I tried the same old routine method of debugging, which is the best... puts( ).. It was all due to the assignment statement in devices_init( ) in devices.c "gd->flags |= "..... which is declared using DECLARE_GLOBAL_DATA_PTR in asm/global_data.h
Well as of now i have commented that, and my board seems to boot fine... But while loading Linux....phew!!! Have a look below...
