We use this chip too and it works fine using U-boot's CFI.  What is your
sector layout (uniform, bottom boot or top boot)?  The additional

Do the U-boot 'protect' and 'erase commands work?  If so, why torture
yourself with low-level access?  If not, you have a configuration or
hardware issue which we can explore.
