I'm thinking that swapping a $2 part for the most expensive item on the menu at Le Cinq next time I'm in Paris is a good investment *smiles*

Probably the only thing you'll have for your 2$ is a smile... and again LOL!

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.

Alain,
What is the manufacturing date code of your 18F1320?

Hi,Luciano
I have 05250SE as a code.
I bought them at the end of last year ( 2005 ) from FARNELL.
I've seen the errata giving an increasing EEPROM Writing time from 4 to 5.5 ms ...
may be, MPLAB didn't follow ...
something strange is I have to program it in 4 times ( ! ) to get 100% success
1) Erase all
2) Config words only( Ok only at second pass ...)
3) Program only
4) EEPROM only
setting to "Auto select" fails at each trail ... " Erase all at first" too

Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!

Maybe MPASM don't follow or just consider the newer device... I'll not be surprise if so...
Let's see what Melanie will discover with her brand new version.

Acetronics, Last year I worked on a project for almost 4 months trying to get an 18F1320 to operate @ 40 Mhz. and then @ 20 Mhz. with eratic results. After looking at the data sheet I decided to use the 16F88 and have never gone back to the 18F1320. The errata sheets tell all. I ordered parts from DigiKey and they said that they had the latest hardware on hand but after receiving 50 parts of an old revision I gave up ordering from them. I was on the MicroChip forum for about 2 months and found out that they wern't very stable as far as the PLL goes and very sensitive to power supply variations. Like I said after looking at the data sheets of the 2 I decided to go with the 16F88 and haven't looked back yet. LOL

Alain,
The oscillator speed of your PIC is 20MHz.
Can you try to change "DEFINE OSC 20" in "DEFINE OSC 25" and flash
the PIC running at 20 MHz with this code? If you try that you will
probably increase the EEPROM writing time and see if ONE write is
enough. This is just a test.
Best regards,
Luciano
EDIT:
Are you absolutely sure that the oscillator speed is correct?
