飞凌工程师，我的ok2440 nand flash 坏块？？？怎么回事呀？

擦除fs_yaffs时显示如下：
Please select which region to erase : Esc to abort
0 : offset 0x00000000, size 0x00100000 [boot]
1 : offset 0x00100000, size 0x00040000 [bootParam]
2 : offset 0x00140000, size 0x00100000 [pic]
3 : offset 0x00240000, size 0x002c0000 [MyApp]
4 : offset 0x00500000, size 0x00300000 [kernel]
5 : offset 0x00800000, size 0x03c00000 [fs_yaffs]
6 : offset 0x04400000, size 0x03c00000 [wince]
Are you sure to erase nand flash from page 0x1000, block count 0x1e0 ? [y/n]

Now download and write nand flash part [ fs_yaffs ]
press [USB Port-->transmit] to choose the file

Now, Downloading [ADDRESS:30800000h,TOTAL:51228682]
RECEIVED FILE SIZE:51228682

Now, Checksum calculation
Download O.K.

Now write nand flash page 0x1000 from ram address 0x30800000, filesize = 51228682
Program nand flash fail

试了好几次，每次都一样，下载成功，就是写flash时错误：
Now write nand flash page 0x1000 from ram address 0x30800000, filesize = 51228682
Program nand flash fail
怎么回事？

把flash用h-flasher擦除一下

同样的问题，
把flash用h-flasher擦除一下，
还是不行。

试试我这个boot,下载到boot分区，餐厨文件系统分区，再重新下载

用了 OK_TE_2440bootV5.rar (23.76 KB)
下载后提示成功了！

我也是这个问题哦，能不能讲讲为什么呀？谢谢

一般是操作不当，破坏了NAND的坏块标志
