| Debug of 18F86J50 |

i'm tring to debug this code, with 18F86J50 and Microchip ICD2, but i cannot enter debug mode. I use a 16Mhz oscillator and the code works if programmed but not if debugged. Can you help me ?
(the actual code is bigger but i made a simple test code to try debugging)
This is the code:
| Code: | #include "main.h"
#bit PLLEN = 0xf9b.6
void main()
{
PLLEN = 1;
setup_adc_ports(ALL_ANALOG|VSS_VDD);
setup_adc(ADC_CLOCK_INTERNAL|ADC_TAD_MUL_0);
setup_psp(PSP_DISABLED);
setup_spi(SPI_SS_DISABLED);
setup_wdt(WDT_OFF);
setup_timer_0(RTCC_INTERNAL);
setup_timer_1(T1_DISABLED);
setup_timer_2(T2_DISABLED,0,1);
setup_timer_4(T4_DISABLED,0,1);
setup_comparator(NC_NC_NC_NC);// This device COMP currently not supported by the PICWizard
//Setup_Oscillator parameter not selected from Intr Oscillator Config tab
while(1);
} |
| Code: |
#include <18F86J50.h>
#device adc=8
#FUSES NOWDT //No Watch Dog Timer
#FUSES WDT128 //Watch Dog Timer uses 1:128 Postscale
#FUSES H4_SW //High speed osc with SW enabled 4x PLL
#FUSES DEBUG //No Debug mode for ICD
#FUSES NOXINST //Extended set extension and Indexed Addressing mode disabled (Legacy mode)
#FUSES STVREN //Stack full/underflow will cause reset
#FUSES NOPROTECT //Code not protected from reading
#FUSES FCMEN //Fail-safe clock monitor enabled
#FUSES IESO //Internal External Switch Over mode enabled
#FUSES CCP2E7 //CCP2 input/output multiplexed with RE7
#FUSES NOCPUDIV
#FUSES PLL4 //Divide By 4(16MHz oscillator input)
#use delay(clock=48000000,oscillator=16000000)
#use rs232(baud=9600,parity=N,xmit=PIN_C6,rcv=PIN_C7,bits=8) |

Compile with :
To allow ICD2 debugging.

also with
it doesn't work.
Maybe it's not a software problem, but it's weird because if i program the code it works, if i try to debug it it can't enter debug mode. |

You didn't tell us which debug tool are you using, because if you are working under:
1) MPLAB you must install the CCS plugin.
2) PCWx IDE - as long as I know - it does not support the ICD2.
Did you do the MCU target detection test prior to try the debugging test?

I'm using MPLAB with ICD2 and plugin (note that other chips goes into debug mode only this one got a problem)
PCWx has a new beta plugin and it works with ICD2, but with this particular IC i can't debug (but i can program it)
On the same board i have another micro (18F2550) and it goes into debug mode ! |
