After booting with u-boot I want replace U-boot binary in NOR flash(EFF80000-EFFFFFFF) with my boot loader and reset the board to boot with my binary but I couldn't do due to NOR flash protection mechanism.
my requirement is like below...
1) boot the board using u-boot
2) replace u-boot with my binary in NOR flash
3) enter "reset" in u-boot console
4) Now when the board boots my binary will be mapped to bootspace...so board should boot with my binary.
