In the flash, I have the following partitions in a flash:

 

mtd0 : u-boot-1.1.4

mtd1 : rootfs

mtd2 : env

mtd3 : rootfs_upgrade

…

 

I noticed that uboot search the entire flash for uImage.  If I have 2 uImage (i.e. 2 root filesystems) in the flash, it will fail to boot up.  What I did is to lie the memory size to u-boot so that it only search from mtd0 to mtd2.

 

Is there any command I can set to change where it is booted from?  (dev/mtd1 or dev/mtd3)

 

Thanks for your help.

 

Regards,

 

Terence
