I think I found the solution. I changed my configuration als follows:

Removed the #undef CONFIG_ENV_ADDR_REDUND
Added

#define CONFIG_ENV_OFFSET_REDUND    (CONFIG_ENV_OFFSET + CONFIG_ENV_SIZE)
#define CONFIG_ENV_SIZE_REDUND    CONFIG_ENV_SIZE

Changed my mtdparts to:

#define MTDPARTS_DEFAULT        
"mtdparts=physmap-flash.0:256k(uboot)ro,128k(ubootenv),128k(ubootenv_re),4096k(kernel)"

So mtd in u-boot showd:

device nor0 <physmap-flash.0>, # parts = 3
  #: name                size            offset          mask_flags
  0: uboot               0x00040000      0x00000000      1
  1: ubootenv            0x00020000      0x00040000      0
  2: ubootenv            0x00020000      0x00060000      0
  3: kernel              0x00400000      0x00080000      0

I changed fw_env.h to #define HAVE_REDUND.

And the fw_env.config:

/dev/mtd2        0x0000        0x20000        0x20000
/dev/mtd3        0x0000        0x20000        0x20000

So now it's working with the redundant environment partitions. Thanks 
for your support
