VP 390 and AT89C51RD2 Reply

 I am trying to use VP390 and Ver 4.6.0 to program Atmel AT89C51RD2 using the WL-P44-P4 adapter. When I load the file and program the part, it verifies but the part does not operate. When I read the data it appears OK

When I try a known good programmed part and Read from the chip into the buffer then all locations appear as FF.

What else do I need to check?

 It may be secure. Please edit and prog. config. If you want read file from chip, you don"t lock LB0--LB2.
