I am using u-boot-2009.03 and linux kernel 2.6.27. I have some questions about the bad block handling of OneNAND. 1. How does the u-boot handle bad block for onenand? 2. If u-boot is creating a bad block table, does it need to pass to the kernel? If not, how to ensure their bad block table are in sync? 3. How to deal with bad blocks after the writing of the u-boot, kernel and rootfs image? Is it the job of UBI? Thanks in advance. Best regards, Geiger
