I have browsed the website, http://www.denx.de/twiki/bin/view/DULG/Manual. For this example: 0x00000000-0x00060000 : "U-Boot" 0x00060000-0x00080000 : "Environment 1" 0x00080000-0x000A0000 : "Environment 2" 0x000A0000-0x000C0000 : "ASIC Images" 0x000C0000-0x001C0000 : "Linux Kernel" 0x001C0000-0x005C0000 : "Ramdisk Image" 0x005C0000-0x01000000 : "User Data"
How can I put the Environment variables or configurations in 0x00060000-0x00080000, or put User Data in 0x005C0000-0x1000000? Use U-boot command? Or....

Then avoid writing it that often.

You can use MTD to provide an additional file system which can then be mounted by one of your startup scripts. MTD configuration and file system building is documented in the DULG, please see http://www.denx.de/twiki/bin/view/DULG/Manual It is not possible to give good advice how to split data into separate file systems, or how exactly you can mount it without precise knowledge of your system and it's requirements. For example, do you use a SysV init with several run levels, or a simple setup for example based on busybox? In the end this is something which you have to design yourself.
