Now I changed my settings as follows:
#define PHYS_FLASH_SIZE 0x000400000 /* 4 MB */ ...
This is mine:
#define CFG_ENV_IS_IN_FLASH 1 #define CFG_ENV_SECT_SIZE 0x40000 /* 256K (one sector) for env */ #define CFG_ENV_SIZE CFG_ENV_SECT_SIZE #define CFG_ENV_ADDR 0xffe00000
I have a 256KB sized-sector flash, u-boot (512KB) at 0xFFF80000 (at the end of flash) and the environment at 0xFFE00000 (1 sector).
Now I can make saveenv, but after restart the bootloader is damaged!
This probably means that you're setting your environment to overlap u-boot's flash area. Check your memory map and (re-)read the file README in u-boot's root directory about the environment's configuration defines.

Hmmmm.... I see what my mistake was! My ENV was on the same address like U-BOOT!
U-BOOT is now on address 50000000. The ENV on 50010000!
I checked this address and I was clear! No data was on it, so I thougt I could use the section for my ENV. But when I make saveenv the bootloader is dead!? Why?
According to the above, your sector size is 0x40000 (256K) but you stored your ENV at u-boot + 0x10000 (64K) which is in the same sector as u-boot. When you erased your ENV area, you inadvertently erased u-boot as well since it is all in one sector.
