[U-Boot-Users] Problem Erase/Program Flash using BDI2000 on PQ2FADS-ZU (8280) board

[KokHow Teh]

Hi;
      I am using PQ2FADS-ZU board with MPC8280 processor. I have problem
erasing the flash sector from 0xfff00100 to 0xfff0028f. As a result, I am
not able to program the U-Boot into this reset vector. Anybody able to help
me with this? Attached below is my BDI2000 output as well as the
PQ2FADS-ZU.cfg that I use with BDI2000.
      Thanks for any insight.
