The problem was the definition of CONFIG_ENV_ADDR_REDUND after undefining this it works.
Do you understand the consequewnces of removing this definition? Are you sure you really want to do this?
Best regards,

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
