These devices have a voltage different from writing that of reading, your problem can be the soft TOPWIN, that version you have? you can unload the last version of http://www.top2048.com/gb/soft.htm

help.
Perhaps the tension for programming is'nt correct.
(With write command the software stop in first addres and display this error "file=00 chip=ff").
I ask, is possible to forced the programming voltage whit external tension without damage the top programmer?
The top2004 programmer factory have a consumer suport mailbox?

Best Regard
