Code programming error at 0000

EPIC is certainely one of the best lowest-cost programmer anyways.

I use Microchip PICSTART Plus and BK Precision 844a (relabeled of an Elnec)
Microchip ICD-2 seems to be another great one.

I just sent an email to MeLabs yesterday to see if they know a solution.

I'm having a problem programming about 10% of my brand new 18F2525 chips. Very annoying to have 10% "bad" chips at $6.11 each!!

Some fail at 0000 and some make it almost to the end before failing. Like I said, 90% program with no problems. All using the same hex file and settings.

Erasing is no help. Also using latest software with MeLabs Serial Programmer.

I just want to know, is it the programmer or Microchip quality control??

Well i didn't had any bad chip as now. And it's not because i didn't wanted

I'd some bad experience, but as Melanie said, i set Erase before programming... and as now (finger crossed) i never had any bad experience. MAYBE a programmer problem. I don't have the EPIC so can't really be sure of it.

Is this the serial or the parrallel model?

If it's the parrallel, I saw kinda patch about XP printer polling blah blah...

Same problem on another Computer?

Jeff Schmoyer at MeLabs returned my email. He pointed me to a capacitor mod for the serial programmer:

This solved my problems.

Kudos to MeLabs for the prompt reply!
