[zhou.yanqing at zte.com.cn]

Hello all:

 
        I have a DaVinci DM6446 EVM board with 32MB K9F5608R0D(NAND 
Flash). The latest u-boot-2009.03 with yaffs2 compiled in can run on this 
board from Nand Flash. when running the command "ywr",the U-Boot dumps 
some error as such:

U-Boot > ywr /test.txt 0 5
Writing value (0) 5 times to /test.txt... yaffs tragedy: no more eraased 
blocks
Error opening file: -1
done"

        How to use the yaffs2 in u-boot-2009.03 ? Somebody can help me?

        Thanks very much!
