| PIC24FV32KA304 - PUT fuse not configured |

HI All
am working on a Project in PIC24FV32KA304 with CCS PCD Compiler Version 4.130.
I am enabling the PUT fuse in the header file. as below.
| Code: | #include <24FV32KA304.h>
#device ICD=TRUE
#FUSES WPOSTS1 //Watch Dog Timer PostScalar 1:1
#FUSES FRC_PLL //Internal Fast RC Oscillatorwith PostScalar and 4X PLL
#FUSES NOIESO //Internal External Switch Over mode disabled
#FUSES NOCKSFSM //Clock Switching is disabled, fail Safe clock monitor is disabled
#FUSES NOWINDIS //Watch Dog Timer in Window mode
//#FUSES NOBROWNOUT //No brownout reset
//#FUSES NOPUT //No Power Up Timer
#FUSES BORV_MID
#FUSES PUT //Power Up Timer
#FUSES DEBUG //Debug mode for use with ICD
#FUSES ICSP3 //ICD uses PGC3/PGD3 pins
#FUSES NODSBOR //BOR disabled in Deep Sleep
#FUSES NODSWDT //Deep Sleep Watchdog Timer disabled
#FUSES NODSWDT //Deep Sleep Watchdog Timer disabled
#FUSES PROTECT //Code protected from reads
#FUSES SOSC_DIGITAL
#FUSES OSCIO //OSC is general purpose output |
After compilation, when i check the configuration bits in MPlab IDE ,still it shows " PWRT Disabled".
I checked for other configuration bits. It works fine. only the PUT is not configuring properly.
So, every time after compilation i have to change that manually before programming.
Anyone have any idea how to resolve this? is it possible to fix it in code without changing the config manually??
Thanks

It's because you have debug selected.
In common with things like WDT, this is disabled when ICD is selected.
If you read the ICD manual, this is referenced. Not a CCS problem, but an oddity of ICD....

Hi Ttelmah
Thanks for your response.
I tried after disabling the "debug" fuse and still am getting the same.
is anything else am missing here???
| Code: | #include <24FV32KA304.h>
//#device ICD = True
#FUSES WPOSTS1 //Watch Dog Timer PostScalar 1:1
#FUSES FRC_PLL //Internal Fast RC Oscillatorwith PostScalar and 4X PLL
#FUSES NOIESO //Internal External Switch Over mode disabled
#FUSES NOCKSFSM //Clock Switching is disabled, fail Safe clock monitor is disabled
#FUSES NOWINDIS //Watch Dog Timer in Window mode
#FUSES NOBROWNOUT //No brownout reset
//#FUSES NOPUT //No Power Up Timer
//#FUSES BORV_MID
#FUSES PUT //Power Up Timer
//#FUSES DEBUG //Debug mode for use with ICD
#FUSES ICSP1 //ICD uses PGC3/PGD3 pins
#FUSES NODSBOR //BOR disabled in Deep Sleep
#FUSES NODSWDT //Deep Sleep Watchdog Timer disabled
#FUSES NODSWDT //Deep Sleep Watchdog Timer disabled
#FUSES PROTECT //Code protected from reads
#FUSES SOSC_DIGITAL
#FUSES OSCIO //OSC is general purpose output |
Even I disabled #device ICD = also.
Thank you

Are you compiling through MPLAB?.
If so, this sets the chip to debug mode by default. You need to set this to release mode to override it.
You don't need the DEBUG fuse, selecting ICD automatically sets this.
Try a simple test, compile in CCS 'only', and look at the fuses at the end of the .lst file.
With ICD selected:
| Code: |
Configuration Fuses:
Word 1L: 000F NOWRTB NOBSS
H: FF00
Word 2L: 0000
H: FF00
Word 3L: 0003 NOWRT NOPROTECT
H: FF00
Word 4L: 0041 FRC_PLL SOSC_DIGITAL LPRCHIGH NOIESO
H: FF00
Word 5L: 00BB NOPR OSCIO POSCFREQ_H SOSC_HIGH NOCKSFSM
H: FF00
Word 6L: 0010 WPOSTS1 WDT128 NOWINDIS NOWDT
H: FF00
Word 7L: 00D7 BROWNOUT NOLVR NOPUT NOALTI2C BORV_MID MCLR
H: FF00
Word 8L: 0003 ICSP1 DEBUG
H: FF00
Word 9L: 001F DSWDT2147483648 DSWDTCK_LPRC NODSBOR NODSWDT
H: FF00
Some fuses have been forced to be compatible with the ICD debugger.
|
Then with ICD turned off:
| Code: |
Configuration Fuses:
Word 1L: 000F NOWRTB NOBSS
H: FF00
Word 2L: 0000
H: FF00
Word 3L: 0001 NOWRT PROTECT
H: FF00
Word 4L: 0041 FRC_PLL SOSC_DIGITAL LPRCHIGH NOIESO
H: FF00
Word 5L: 00BB NOPR OSCIO POSCFREQ_H SOSC_HIGH NOCKSFSM
H: FF00
Word 6L: 0010 WPOSTS1 WDT128 NOWINDIS NOWDT
H: FF00
Word 7L: 00DF BROWNOUT NOLVR PUT NOALTI2C BORV_MID MCLR
H: FF00
Word 8L: 0081 ICSP3 NODEBUG
H: FF00
Word 9L: 001F DSWDT2147483648 DSWDTCK_LPRC NODSBOR NODSWDT
H: FF00

Note the comment disappearing, the PUT fuse being selected, and the DEBUG fuse automatically changing.

Hi Ttelmah
Thanks.
Yes I am using Mplab IDE for compiling.
yeh its working now after i disable the "Compile for use with ICD debugger" option in Project build options.
But , the Mplab ide doesn't show up the checksum after compilation. even if i import also i doesn't.
I am using that for tracking the hex file without opening it.
is there any other way to get that??
Thanks for your valid time.
Thanks

If you are not using the ID for anything else, if you use #ID CHECKSUM in the code, then you can look at the ID memory, and see this. - configure - ID memory, and it'll show the checksum.
