| ICD2 problem |

Hi , well this is my first post so don't be bad  . I am running CCS compiler under MPLAB, using the microchip ICD2 debugger , in debug mode it works fine, but if I use the ICD2 in programmer mode my program doesn't run on the PIC although mplab says ....programming succeeded. Any suggestions??
Thank's in advance.
Regards. |

| After programming, did you remove the programming cable? With the cable attached the ICD2 will keep the PIC in reset mode unless you select the 'release from reset' button in MPLAB (the button with the up arrow). |

Yep I remove the programming cable but it still doesn't work, I don't find that button with the up arrow. By the way I am using mplab 6.40 but that shouldn't be a problem.

What chip are you using?
Are you using an 18F series in 4xPLL mode? |

No, I am using a PIC16F873. It's a strange thing what happens, works perfect in debug mode but in programmer mode it does nothing.

| The earlier versions allowed you to load the Debugger and the Programmer at the same time. If your version does this, make sure that you have the debugger configuration turned off. |

| I don't have a pull-up resistor on MCLR and I disable debugger mode before enabling programmer mode. |

Well you need one on it. Look up the schematic of a PIC demo board, like a PICDEM 2 PLUS, from Microchip's website. Look at how they connect MCLR. |

Thank's everybody, it was that, I have just soldered the pull up resistor and everything goes fine.
