Hi all,

I have the following problem:
1) I check that the device is blank and it is
2) I change the first couple of bytes on the editor
3) I click on program.
- when the EPROM Memory is ticked I get 'Program Error' flashing
in the status bar
- when I untick it then it does 0.296s and says Successful. BUT
when I verify it's clear that there has been no change in the chip.

Since I am a junior here, can you please give me the first push?

THanks a lot in advance

Regards
aris

The chip need to be erased before write any new data. Even one byte data changed, whole chip have to be erased under UV eraser.
