[U-Boot-Users] Use reset CMD to start another u-boot failed.

The original u-boot running on board was burn AT 0xFFF00000,
(Flash is mapped to 0xFE000000-0xFFFFFFFF)
The CFG_RESET_ADDRESS = 0xFE000000

The original and new u-boot file difference is only two place.
1. CONFIG_AUTOBOOT_PROMPT (use it to verify the new u-boot startup correctly)
2. board/myboard/config.mk->TEXT_BASE = 0xFE000000
Then I place the new u-boot.bin file to the 0xFE000000,
and then run the "reset" cmd from original u-boot's prompt.

but it's seem the new u-boot was not startup.
the console still print the original u-boot's CONFIG_AUTOBOOT_PROMPT.

Am I miss some step? Or some where need to pay attention to?

============
The original u-boot flinfo.
Original u-boot.bin was place to the FFF00000-FFF3FFFF(2 sector)
CFG_ENV_ADDR = FFF40000(1 sector),CFG_RESET_ADDRESS = 0xFE000000
