Yes. You are right. It's design by myself. But I meet a problem. If I have three configuration files, A.conf, B.conf and C.conf, then I hope save them in one of partitions of MTD, 0x005C0000-0x10000000. Two questions: 1. How to build these configuration files into an image for U-boot with mkimage? 2. In kernel, how to get these data? I use "mount /dev/mtd4 /mnt", but it failed by block device required.

Or.... It is up to you to define a memory map for your flash device(s) and create appropriate partitions for this map in Linux (and probably in U-Boot, too, using the new "mtdparts" command). Then you can use standard commands in U-Boot (erase, cp) and in Linux (erase_all, cp) to store any data you likein your flash. It is *your* design. *You* must create it.
