Advice please - Warning message

The PICpgm appliaction doesn't have any options to change, so I assume it takes the fuse settings etc from the code / inc / dev files.

In theory ... yes

Reading the code back into WinPIC, gives the following info in the log
''''
'
'
'
'
I Then loaded the same HEX file that gets compiled from your code that I previously loaded with PICpgm into Winpic and it reported the following under device config

Config word #1 = F0E7 (hex)
Config word #2 = 1F3F (hex)

One is good ... where the other 'I think' don't make sense at all

Let's say i just compile the config fuses bellow

ASM
    __CONFIG  _CONFIG1L, _CPUDIV_OSC1_PLL2_1L  
    __CONFIG  _CONFIG1H, _FOSC_XT_XT_1H
    __CONFIG  _CONFIG3H, _PBADEN_OFF_3H
    __CONFIG  _CONFIG4L, _LVP_OFF_4L & _XINST_OFF_4L
ENDASM

now, if i open the .LST file, i found

                      00097 
                      00098     __CONFIG  _CONFIG1L, _CPUDIV_OSC1_PLL2_1L  
300000 F0E7           00099     __CONFIG  _CONFIG1H, _FOSC_XT_XT_1H
300004 FDFF           00100     __CONFIG  _CONFIG3H, _PBADEN_OFF_3H
300006 FFBB           00101     __CONFIG  _CONFIG4L, _LVP_OFF_4L & _XINST_OFF_4L

Where those numer comes from. Open the p18F2550.INC in the MPASM foler, scroll to the bottom and you'll discover

_CONFIG1L        EQU  H'300000'
_CONFIG1H        EQU  H'300001'
_CONFIG2L        EQU  H'300002'
_CONFIG2H        EQU  H'300003'
_CONFIG3H        EQU  H'300005'
_CONFIG4L        EQU  H'300006'

let's see CONFIG1L and CONFIG1H options

;----- CONFIG1L Options --------------------------------------------------
_PLLDIV_1_1L         EQU  H'F8'    ; No prescale (4 MHz oscillator input drives PLL directly)
_PLLDIV_2_1L         EQU  H'F9'    ; Divide by 2 (8 MHz oscillator input)
_PLLDIV_3_1L         EQU  H'FA'    ; Divide by 3 (12 MHz oscillator input)

_PLLDIV_5_1L         EQU  H'FC'    ; Divide by 5 (20 MHz oscillator input)
_PLLDIV_6_1L         EQU  H'FD'    ; Divide by 6 (24 MHz oscillator input)
_PLLDIV_10_1L        EQU  H'FE'    ; Divide by 10 (40 MHz oscillator input)
_PLLDIV_12_1L        EQU  H'FF'    ; Divide by 12 (48 MHz oscillator input)

_CPUDIV_OSC1_PLL2_1L EQU  H'E7'    ; [OSC1/OSC2 Src: /1][96 MHz PLL Src: /2]
_CPUDIV_OSC2_PLL3_1L EQU  H'EF'    ; [OSC1/OSC2 Src: /2][96 MHz PLL Src: /3]
_CPUDIV_OSC3_PLL4_1L EQU  H'F7'    ; [OSC1/OSC2 Src: /3][96 MHz PLL Src: /4]
_CPUDIV_OSC4_PLL6_1L EQU  H'FF'    ; [OSC1/OSC2 Src: /4][96 MHz PLL Src: /6]

_USBDIV_1_1L         EQU  H'DF'    ; USB clock source comes directly from the primary oscillator block with no postscale
_USBDIV_2_1L         EQU  H'FF'    ; USB clock source comes from the 96 MHz PLL divided by 2

;----- CONFIG1H Options --------------------------------------------------
_FOSC_XT_XT_1H       EQU  H'F0'    ; XT oscillator, XT used by USB
_FOSC_XTPLL_XT_1H    EQU  H'F2'    ; XT oscillator, PLL enabled, XT used by USB
_FOSC_ECIO_EC_1H     EQU  H'F4'    ; External clock, port function on RA6, EC used by USB
_FOSC_EC_EC_1H       EQU  H'F5'    ; External clock, CLKOUT on RA6, EC used by USB
_FOSC_ECPLLIO_EC_1H  EQU  H'F6'    ; External clock, PLL enabled, port function on RA6, EC used by USB
_FOSC_ECPLL_EC_1H    EQU  H'F7'    ; External clock, PLL enabled, CLKOUT on RA6, EC used by USB
_FOSC_INTOSCIO_EC_1H EQU  H'F8'    ; Internal oscillator, port function on RA6, EC used by USB
_FOSC_INTOSC_EC_1H   EQU  H'F9'    ; Internal oscillator, CLKOUT on RA6, EC used by USB
_FOSC_INTOSC_XT_1H   EQU  H'FA'    ; Internal oscillator, XT used by USB
_FOSC_INTOSC_HS_1H   EQU  H'FB'    ; Internal oscillator, HS used by USB
_FOSC_HS_1H          EQU  H'FC'    ; HS oscillator, HS used by USB
_FOSC_HSPLL_HS_1H    EQU  H'FE'    ; HS oscillator, PLL enabled, HS used by USB

_FCMEN_OFF_1H        EQU  H'BF'    ; Fail-Safe Clock Monitor disabled
_FCMEN_ON_1H         EQU  H'FF'    ; Fail-Safe Clock Monitor enabled

_IESO_OFF_1H         EQU  H'7F'    ; Oscillator Switchover mode disabled
_IESO_ON_1H          EQU  H'FF'    ; Oscillator Switchover mode enabled

using our settings, we keep

_CONFIG1L        EQU  H'300000'
_CONFIG1H        EQU  H'300001'
_CPUDIV_OSC1_PLL2_1L EQU  H'E7'  
_FOSC_XT_XT_1H       EQU  H'F0'

combining both L and H we have F0E7... same for all other Config stuff.

It doesn't explain your config2 stuff... If it's a config fuse, it's not valid, well i don't see how we can have 1F... it could be a device programmer behaviour... i think

let's try to set ALL available config fuses BUT NOT the code protect stuff. And while we're at it, let's try a simple program too.

ASM
    __CONFIG  _CONFIG1L, _PLLDIV_1_1L & _CPUDIV_OSC1_PLL2_1L & _USBDIV_1_1L 
    __CONFIG  _CONFIG1H, _FOSC_XT_XT_1H & _FCMEN_OFF_1H  &  _IESO_OFF_1H 
    __CONFIG  _CONFIG2L, _PWRT_ON_2L & _BOR_ON_2L &  _BORV_1_2L  & _VREGEN_OFF_2L 
    __CONFIG  _CONFIG2H, _WDT_OFF_2H 
    __CONFIG  _CONFIG3H, _MCLRE_ON_3H & _LPT1OSC_OFF_3H & _PBADEN_OFF_3H & _CCP2MX_OFF_3H 
    __CONFIG  _CONFIG4L, _STVREN_ON_4L & _LVP_OFF_4L & _XINST_OFF_4L & _DEBUG_OFF_4L 
ENDASM
ADCON1=$0F
TRISB=%00000000                  'set PORTB as all output
PORTB=0

ByteA   var byte
 
main:
    for bytea=0 to 7
        PORTB=DCD BYTEA
        PAUSE 250
        NEXT
    PORTB=255
    PAUSE 250
    goto main

now it give us those config values

                      00102     __CONFIG  _CONFIG1L, _PLLDIV_1_1L & _CPUDIV_OSC1_PLL2_1L & _USBDIV_1_1L 
300000 30C0           00103     __CONFIG  _CONFIG1H, _FOSC_XT_XT_1H & _FCMEN_OFF_1H  &  _IESO_OFF_1H 
                      00104     __CONFIG  _CONFIG2L, _PWRT_ON_2L & _BOR_ON_2L &  _BORV_1_2L  & _VREGEN_OFF_2L 
300002 FECE           00105     __CONFIG  _CONFIG2H, _WDT_OFF_2H 
300004 F8FF           00106     __CONFIG  _CONFIG3H, _MCLRE_ON_3H & _LPT1OSC_OFF_3H & _PBADEN_OFF_3H & _CCP2MX_OFF_3H 
300006 FFBB           00107     __CONFIG  _CONFIG4L, _STVREN_ON_4L & _LVP_OFF_4L & _XINST_OFF_4L & _DEBUG_OFF_4L 
                      00108

and it's still working here. here's the .HEX dump

compare with yours.

In both cases nothing is else is listed listed (see images attached) If I try programming having loaded this file it errors

Wich adapter you're using JDM?

ICSP or not?

When you program your PIC, pull the PGM pin to GND, erase the chip firstm then retry and post your results.

I can't comment on JDM or else programmer like that, if you want a nice one and cheap, i buyed few months ago a Microchip PICKit 2 for some on-the road service job. For a <40$ and USB PIC programmer it's really nice.

I'm really out of my depth here as I have no idea what all these numbers are - I opted for the PICpgm program because it auto detected the PIC and had less setting to change - it also seemed to work as it reported no errors

Yeah it's kind of hard to know where the problem come from... The most strange thing... only one a single pin... and you tried on another board...

Don't give up!
