Question for LS1021A RCW configuration

Hi, Dear NXP Tech Support Team:

I want to confirm the RCW value of the LS1021A  board I am working on when it came out of the factory and noticed that there is an example on page 2 of the doc AN5089, is that just an example or the actual RCW for the LS1021A board? My board has exactly the same RCW value what the example says, but it is not working on our system, the serial output stops after showing 'DRAM: 1 GiB'. 
But the documents show this board was working before when the middle of the last line of the RCW was '281b7340' as what shows in the attached image at the bottom of this question. I do not have the background of this board and do not know if its RCW had been programmed to be '281b7340' after we purchased. 
So the question is which one is the factory default set, '881b7340' or '281b7340' or any other?
CPU: Freescale LayerScape LS1021E, Version: 2.0, (0x87081120)

Bus:300 MHz, DDR:800 MHz (1600 MT/s data rate),
Reset Configuration Word (RCW):

00000010: 70000000 00007900 e0025a00 21046000
00000020: 00000000 00000000 00000000 20000000
00000030: 00080000 281b7340 00000000 00000000
Thanks
Kevin
