Bit Debug on PIC24F16KA101
PostPosted: Fri Jun 17, 2022 9:57 am     Reply with quote

Hello,
Excuse my English, I'm French.
I wrote a program for a pic 24F16KA101.
With the following fuses:
Code:
Code:
#include <24F16KA101.h>

#FUSES NOWDT            //Pas de Watch Dog
#FUSES CKSFSM           
#FUSES NOWRT
#FUSES NOPROTECT
#FUSES NOWDT
#FUSES FRC
#FUSES NODEBUG

The program compiles very well.
But when I load it into Mplab-IPE, it tells me that the Debug bit is set, etc...and of course the PIC doesn't boot.
Yet when I look at the .HEX, the bits are set correctly.
Code:

Configuration Words
   F80000: FF00000F FF000000 FF000003 FF000080
   F80008: FF00003F FF00004B FF0000F3 FF000042
   F80010: FF0000FF

Word @F8000E (FICD): 0x42 when it should be 0x82
Bit 7 to 1 for nodebug
What's going on?
Thank's you

Historically MPLAB, the default mode of the build is 'DEBUG' not 'RELEASE' mode.
I use version 8.92 (last one..)
In the main menu, select project, build configuration, release.

hope this is the fix !

temtronic, he's using MPLAB X. Your post applies to MPLAB 8.

Regarding the debug bit problem, see this post:
http://www.ccsinfo.com/forum/viewtopic.php?t=59754
It was solved by setting the correct PIC device in MPLAB X.

Hello,
I wrote a mini program to test the configuration bits.

Code:

#include <24F16KA101.h>

#FUSES NOWDT                    //No Watch Dog Timer
#FUSES CKSFSM                   //Clock Switching is enabled, fail Safe clock monitor is enabled
#FUSES NOWRT
#FUSES NOPROTECT
#FUSES NOBROWNOUT               //No brownout reset
//#FUSES NODEBUG

//#device ICD=2

#use delay(internal=4000000)

#define retro PIN_B7    //rétroéclairage

void main()
{
   set_tris_A(0b01000100);             
   set_tris_B(0b0000001100000000);     

   while(TRUE)
   {
         output_high(retro);   

   }


By default, without specifying (NO)DEBUG. Bits config is correct (ICSP1 & NoDebug). Copy file from .lst
Code:

Configuration Fuses:
   Word  1L: 000F   NOWRTB NOBSS
          H: 0000 
   Word  2L: 0000 
          H: 0000 
   Word  3L: 0003   NOWRT NOPROTECT
          H: 0000 
   Word  4L: 0087   FRC_DIV IESO
          H: 0000 
   Word  5L: 003F   NOPR NOOSCIO POSCFREQ_H SOSC_HIGH CKSFSM
          H: 0000 
   Word  6L: 005F   WPOSTS16 WDT128 WINDIS NOWDT
          H: 0000 
   Word  7L: 00F8   NOBROWNOUT PUT NOALTI2C1 BORV_LOW MCLR
          H: 0000 
   Word  8L: 00C3   ICSP1 NODEBUG
          H: 0000 
   Word  9L: 00FF   DSWDT2147483648 DSWDTCK_LPRC RTCCK_SOSC DSBOR DSWDT
          H: 0000


If I define the ICSP2 ports by #define ICD=2, The config is not good, even specifying NODEBUG.
Code:

Configuration Fuses:
   Word  1L: 000F   NOWRTB NOBSS
          H: 0000 
   Word  2L: 0000 
          H: 0000 
   Word  3L: 0003   NOWRT NOPROTECT
          H: 0000 
   Word  4L: 0087   FRC_DIV IESO
          H: 0000 
   Word  5L: 003F   NOPR NOOSCIO POSCFREQ_H SOSC_HIGH CKSFSM
          H: 0000 
   Word  6L: 005F   WPOSTS16 WDT128 WINDIS NOWDT
          H: 0000 
   Word  7L: 00F0   NOBROWNOUT NOPUT NOALTI2C1 BORV_LOW MCLR
          H: 0000 
   Word  8L: 0042   ICSP2 DEBUG
          H: 0000 
   Word  9L: 00FF   DSWDT2147483648 DSWDTCK_LPRC RTCCK_SOSC DSBOR DSWDT
          H: 0000 

   Some fuses have been forced to be compatible with the ICD debugger.


Strange!
Do you have an explanation?

I understood my error.
#device ICD=x is only to be used for debugging

Thank's

Yes.
The ICD=x syntax sets ICD=TRUE, and the port to be used....
