Hello,
I have a Sivava PC50 programmer and I want to program an Intel D8742 chip.
Unfortunately I always have an error at the first byte when writing.
Any idea? I think I set the board up properly. Any advice is welcome!
Thanks!
Chris

Re: Programming Intel D8742
Do you apply external power source ?
Re: Programming Intel D8742
Yes, I use a 12V adapter, and put the jumper to provide 21V and Vpp position. I set the dip switches as shown on the software. I didn't plug the USB cable then.

What result on next adress , read chip and look in buffer ? Try measure Vpp and Vcc during D8742 programming .
