| Stuck in debug again with 18F45K22 [solved] |
 Posted: Tue Apr 29, 2025 1:08 pm |
 |
|
| Code: | #include <18F45K22.h>
#use delay(internal=32MHz)
void main(void)
{
while(TRUE)
{
output_high(PIN_B4);
delay_ms(500);
output_low(PIN_B4);
delay_ms(500);
}
} |
Everything was working fine until I switched to the debugger, now it ONLY works in the debugger. I tried #device ICD=, but no change. Any guidance is greatly appreciated. Compiler is 5.119, programmer is ICD-U64.

In MPLAB, you have to compile in 'release' mode to get PICs to work in the 'real world'. If you compile in 'debug', there's extra stuff added.....
Others with more modern compilers and IDEs will know.. |

| Thank you, but I'm using the CCS compiler. The IDE seems stuck in debug. I've even tried with another MCU on another project. |

Ok the IDE has to have an 'option' to 'build' in 'debug ' or 'release' mode.
I'm a dinosaur that still uses PCM through MPLAB.... |

| Thank you again, but that is the rub, there is no release-mode option (that I can find). |

It's controlled by having he debug tab open.
If you select 'debug', it'll open this tab, and ask if you want to recompile.
Once you have done this, so long as this tab remains open, it'll always
compile in debug mode.
Top right corner. Red cross, closes this tab. Then select 'recompile', and it'll
compile without debug.
However 'caveat'. If you have the line ICD=xx in your code it'll always
compile in debug mode. Remark this line out, and the behaviour becomes
controlled by the tab.
Personally I never add the ICD= line to the code. Just have the ICSP=xx
lie to control which pins are used, and let the compiler control the debug
as outlined above. |

Thank you for the reply, but the Debug tab is not open, nor is the ICD = TRUE in the code. I normally don't add the 'ICD = ' as well since the compiler prompts for it when Debug is selected. I contacted CCS, here is the response:
| Quote: | Compare the fuses at the bottom of the LST file when you compile for production and when you
compile for debugging. The problem may be a fuse that is changed to be compatible for debugging.
It is also possible a pullup in the ICD makes a difference in the way the program runs. |
Here is a snippet of the LST file for the fuses:
Configuration Fuses:
Word 1: E800 INTRC_IO NOPLLEN PRIMARY_ON FCMEN IESO
Word 2: 3C1E PUT BROWNOUT BORV19 NOWDT WDT32768
Word 3: BF00 CCP2C1 PBADEN CCP3B5 HFOFST TIMER3C0 CCP2D2 MCLR
Word 4: 0081 STVREN NOLVP NOXINST NODEBUG
Word 5: C00F NOPROTECT NOCPB NOCPD
Word 6: E00F NOWRT NOWRTC NOWRTB NOWRTD
Word 7: 400F NOEBTR NOEBTRB
I've tried using the U64 and U80 to no avail. I have tried re-installing the compiler. I have tried programming a different MCU on a different project and now that MCU doesn't work. |

OK.
That is not compiling in debug mode.
How is your MCLR connected????.
Key is the debugger pulls this up. Your fuses have MCLR selected, so this
has to be pulled up. |

| MCLR is connected to +5 through a 10k resistor. However, I just updated the CCSLOAD firmware from 3.61 to 3.62 and the problem appears to be solved. |
