[ixp1200] Problem with programming the flash

Hi All, I am currently trying to program IXP1200 flash with the Intel firmware. I am using flash burner equipment called Topmax which is from the company EEtools. Inspite of following the instructions as mentioned in the manual I am unable to write to the flash. Read from flash is successful, but writes are not happening. Have any of you faced a similar problem? Do I need to take some extra steps before writes are allowed? The device continuously makes attempts to write but in the end is unable to write anything.
