My settings :
boot_flash_base 0x20000000 boot_flash_off 0x200000 boot_flash_sec
0x20000 boot_flash_env_addr 0x200000

I don't want to bother you to much I will look into that. But can you
enlighten me on the fields of the fw_env.config.

Device offset --> if I set /dev/mtd2 and this mtd is the one with the
environment it has to be set to 0x0000
Env. size --> the size is 0x80000
Flash sector size --> is the erase block size so in my case 0x40000
Number of sectors ---> well ... I don't really know :)

I am wrong ?
