Bad block table not found for chip 0 for BSC9131RDB

                     I am working with a BSC9131RDB  board.  We are booting from NAND Flash using Micron MT29F2G08ABAFAWP(256Mb) by replacing K9F1G08U0B(128Mb) NAND.

                     I can program the nand using jtag and uboot recognizes the NAND, Uboot successfully boots to the command prompt.

                      During boot "Bad block table not found for chip 0  No space left to write bad block table" is displayed and I cannot write to the nand chip from u-boot to save the environment or program new u-boot.

  The chip is 256MByte and has a block size = 64 pages (128K + 4K bytes), and 2K pagesize same as K9F1G08U0B but only density increased from 28Mb to 256Mb.


If I run nand bad the whole flash chip is reported as bad.


Has anyone had a similar experiance?  Any ideas what might be causing this?


Thanks for any help.


And the log is :
