About bad block problem in EM2440-III
hey, Can any one help me about my problem posted above. Please tell me if u require additional information. Thanxs.
Can you please provide some more informations about the bootloader you are using? This is a FriendlyArm forum, the board you are using is different from FriendlyArm's board. Bad blocks are finally. After band scrub you create normally a new bad block table with "nand createbbt" when using u-boot as boot loader. This prevents that bad block are tried to been written. If the image is too large for the rest of good blocks, it can't be written.
Hi Titus Breidung, I am using u-boot 1.1.6 if u want more information then please tell me, and suggest me if any solution following is my log while downloading image.

Have you used a suffix according to the image type with your write command? Try nand write.jffs or nand write.jffs2 or nand write.yaffs to flash the image.
U-boot loading YAFFS2 files was news to me! I went to the TI site http://processors.wiki.ti.com/index.php/Put_YAFFS_Image_to_Flash and it looks like U-Boot has been able to do this for years! I was told and therefore told everyone who had similar problems not to use U-Boot for YAFFS2 images and even asked for people to correct me if I was wrong. No one spoke up! I haven't used U-boot for over a year now, so as long as Barebox keeps loading JFFS2 images I'll be happy!
