Advice please - Warning message

Steve,

Ok I've downloaded the latest version of MPLAB so now I'm running ver 5.06 of MPASM and that cured the previous error (FC_MEN_OFF) so the following code compiled fine

Code:

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

The resulting LST file is attached (steve.txt as .lst won't upload) - However when programming it with winpic it errors - here's the log

Code:

On checking the config setting winpic reports 30C0 and FECE as the device config word (#1 and #2 respectively) - see attached image (config.jpg).

When programming MCLR is taken to around +13v by the programmer. Both Vss are connected and grounded.

Lastly here is the resulting HEX file that is compiled

Code:

:020000040000FA
:1000000043EF00F00850070B1A0FF66EF76A000E68
:10001000F722F86A0800F5501200010204081020C7
:100020004080036A026EFF0E0226D8A00326D8A0E5
:1000300040EF00F0030E016EDF0E02D8F4D7016A24
:10004000E80F006E011EFC0ED8A003D00026D8B029
:10005000FDD700260400013EF9D700B000D000A271
:1000600002D0000000D01200086E02EC00F0006A1E
:10007000016A08A6006E08B6016E005040EF00F05D
:100080000001040012000F0EC16E936A816A1C6A9F
:100090000400080E1C5CD8B056EF00F01C50E4DFE2
:1000A000816EFA0EBEDF1C2AD8A4F2D7FF0E816E35
:0600B000FA0EB7DFECD7E9
:020000040030CA
:08000000C030CEFEFFF8BBFF8B
:00000001FF

Comparing the last but one line that was hilighted in your previous post there isn't any difference

Code:

Your code
:08000000C030CEFEFFF8BBFF8B

My code
:08000000C030CEFEFFF8BBFF8B

I therefore tried loading the HEX file via the PICpgm program and that loaded the code to the pic without errors. I then shutdown PICpgm and launched Winpic and read the code back. The log reported the following:

Code:

Info: Loading definitions for "PIC18F2550" from devices.ini .

Couldn't find "C:\Program Files\Microchip\MPLAB IDE\PIC18F2550.dev", please borrow/copy from MPLAB !

Reading 0xF00000 - 0xF000FF ...
Reading 0x000000 - 0x007FFF ...
Reading PIC ok.

The device config words were reported as CF3F and 1F3F. However the resulting dump of the PIC isn't anything like the original file (see dumped.txt attached).

Unless you can see anything glaringly obvious then the only other area must be hardware and until I get a different programmer I can't prove that one way or another. The only thing I can see in the logs is

Couldn't find "C:\Program Files\Microchip\MPLAB IDE\PIC18F2550.dev", please borrow/copy from MPLAB !

Could this be the problem, as the dev files are in C:\Program Files\Microchip\MPLAB IDE\Device folder ??

As always mate, I appreciate your continued help and advice on this one !

EDIT:

Oh and this is the programmer I'm using
