[U-Boot-Users] The command of nand write cannot write zImage to nandflash

[zj_31529]

 Hi all:   I patch NAND (including boot-from-NAND via steppingstone) support to
the S3C2410 SoC code in u-boot(http://svn.openmoko.org/trunk/src/target/u-boot/patches/uboot-s3c2410-nand.patch). The u-boot-1.1.6 print the nandflash info to DNW,and the command of "tftp 0x31000000 zImage" is ok,but the command of "nand write.jffs2 0x31000000 0x2030000 0xc0000 "cannot write the zImage of Linux 2.4 to the nandflash and the u-boot print "Bad block check failed". When I excuted the command of "nand write 0x31000000 0x2030000 0xc0000",the u-boot print "0 bytes writed".   Can you give me a hand.   Thank you very much!

What U-Boot version are you using? 1.1.6? If yes, could you please give the 
current top-of-git version a try. There was a patch a few months ago, that 
fixed a problem where NAND writing aborted, when bad blocks were detected. So 
please give the current version a try and let me know if it helped.

I hope the patch mentioned above does apply without too much problems.

Best regards,
Stefan
