Just looked at what Redboot reported:

++Searching for BBT table in the flash ...                                      
.                                                                               
Found version 1 Bbt0 at block 2047 (0xffe0000)                                  
Block 42 is bad                                                                 
Block 125 is bad                                                                
Block 887 is bad                                                                
Block 1750 is bad                                                               
Total bad blocks: 4   

So the only mismatch is 2046 eraseblock.
