| Controller doesn`t start without programmer?! |

Greetings. I`m using MPlab 8.91, CCS v5.025 and PIC18F67K22.
When I load the program, the microcontroller doesn`t start if the PICkit 3 programmer is not in the ICSP. It`s not in debug mode. When I turn on the power, I just have to put the PICkit into the connector and the controller starts. Otherwise it doesn`t.
Here are my fuses:
| Code: |
#include <18F67K22.h>
#fuses XT,NOWDT
#use delay(clock=10M)
|
Can you tell where to look for the problem?!
Thanks! |

um....
how have you configured the _MCLR pin ??
I know silly to ask but I've been down THAT road before.....
are you powering the PIC from the PICkit instead of 'local' power?
I've done THAT as well.....

I do not use that specific PIC but the most common flaw with the PIC18F is the LVP where the fuse setting to enable LVP by default.
Try adding the fuse NOLVP

I think this NOLVP helped!
Thanks! |

That's the wrong oscillator fuse for 10 MHz. In one of your old posts
you are using the HSH fuse (though it should be HSM for 10 MHz):

Why did you change it to XT ?

18F67K22 doesn't support LVP mode. There is no LVP config bit.
There is no NOLVP fuse. Using it causes the build to fail:

Executing: "C:\Program files\Picc\CCSC.exe" +FH "PCH_Test.c" +DF +LY -T -A +M -Z +Y=9 +EA #__18F67K22=TRUE

This was tested with vs. 5.025.

What are you doing ?
Do you have MPLAB configured for the correct PIC that you are using ? |
