[U-Boot] fw_printernv fw_setenv usage on redundant environment copies

[Amarendra Reddy]

Hi all,



Thanks in Advance. Please help me regarding the below U-Boot problem



I am planning to use fw_printenv & fw_setenv utilities to access U-Boot env variables from Linux Application.



In U-Boot, if we have four "redundant environment" copies in the same partition(mtd1)... Does the below fw_env.config configuration hold good ?

# File: fw_env.config

# Configuration file for fw_(printenv/saveenv) utility.

# Up to two entries are valid, in this case the redundand # environment sector is assumed present.



# MTD device name       Device offset   Env. size       Flash sector size

/dev/mtd1               0x00000         0x02000         0x20000

/dev/mtd1               0x20000         0x02000         0x20000

/dev/mtd1               0x40000         0x02000         0x20000

/dev/mtd1               0x60000         0x02000         0x20000
