Hi,

I look for informations and advices about ICSP. Look informations for the
board side, not programmer side. I went to Microchip website and found only
two relevant answers using query form:
51113 pdf ICSP ä Socket Module User’s Guide
TB016 How to Implement ICSPâ„¢ Using PIC16F8X FLASH MCUs

At the end of the first PDF they speak about :
In-Circuit Serial Programming Guide without other indication.

Thanks for helping.
Dan

Dan,

I  programmed lots of  boards in circuit first boards I tried with crystal
installed
out of 15.000 boards I got 100 bad  then I tried without the crystal
installed
so far I programmed about 4000 boards all of them are passed 100%. My
circuit is
very simple add one diode to master clear pin serially and you are done with
it. you may
need to add another diode on VDD line all depend on how much load do you
have on +5.

That is a familiar symptom: the MCLR rises too slow. when there are too
much clock cycles in the rise time the chip has already advanced its
location counter and ISP will fail. With a better MCLR driver there should
be no problem...
