| Hex file don't works after rebuilding |
 Posted: Mon Mar 24, 2014 5:18 am |

I'm using CCS V5.021 with a multiple compilation project. The pic is a PIC18F26K22.
When I build for the first time the project it works fine, but if I rebuild the project the pic has an erratic functioning, even if I make no changes in the code. I compared both of the .lst files and the second one is a little larger.
So when I change something in my code I have to close the CCS ide and delete ALL created files during the compilation. In the versions 4.xxx it did not happen.
It is a bug of the V5 compiler? |

Try to do it without Multiple Compilation Units. Does it still fail in the
same way ? |

It is strange, it seems that after rebuilding the circuit is more sensible to noise because the firmware hangs when there are connected long wires.
But I still don´t understand why the hex file is different when I rebuild the firmware.
I tried with single compilation unit and the files are still different. |

Regarding your noise problem, see this thread about floating pins:
http://www.ccsinfo.com/forum/viewtopic.php?t=45371
This is a 2-page thread.

So this means you disabled "Multiple Compilation Units" and you added
.c and .h modules to your main C file with #include statements, then you
compiled the main C file.
And then, even after doing that, every time you compile the project, you
still get a different Hex file size every time ? And you're not using MCU's
at all. |

Yes I disabled "Multiple Compilation Units", copy all functions to the main.c file and remove the other files.
When I compile the second time, the hex file is a few bytes larger. The rebuild button should rebuild the whole project again but I don't get the initial size. |

I have compared the .lst files and the differences are in the beginning of the main function, in the "DATA xx, xx" instruction:
