ICD Compile Program in MicroCode Studio Plus

[Mike2545]

I have been trying to get the ICD to connect/work and have had no luck.

I get a message "MIcroCode Studio is unable to connect to the target PIC microcontroller using the assigned serial port."

I have a serial cable going to a MAX 232 chip, following the schematic in the documentation.

Here is my code:

INCLUDE "modedefs.bas"
    include "ALLDIGITAL.pbp"
    DEFINE LOADER_USED 1
    OSCCON =$60 'clock speed 
   '
    DEFINE OSC 4
LED    VAR  PORTB.0' Assign name "LED" to PORTB.0

mainloop:
   High LED        ' Turn on LED connected to PORTB.0
   Pause 500       ' Delay for .5 seconds

   Low LED         ' Turn off LED connected to PORTB.0
   Pause 500       ' Delay for .5 seconds
   Goto mainloop   ' Go back to loop and blink LED forever
   
   End

My configs:

 LIST p = 18F4550, r = dec, w = -311, w = -230, f = inhx32
        INCLUDE "P18F4550.INC"	; MPASM  Header
        __CONFIG    _CONFIG1L, _PLLDIV_5_1L & _CPUDIV_OSC1_PLL2_1L & _USBDIV_2_1L
        __CONFIG    _CONFIG1H, _FOSC_INTOSC_HS_1H  & _FOSC_INTOSCIO_EC_1H & _FCMEM_OFF_1H & _IESO_OFF_1H
        __CONFIG    _CONFIG2L, _PWRT_OFF_2L & _BOR_ON_2L & _BORV_3_2L & _VREGEN_ON_2L
        __CONFIG    _CONFIG2H, _WDT_ON_2H & _WDTPS_512_2H
        __CONFIG    _CONFIG3H, _CCP2MX_ON_3H & _PBADEN_OFF_3H & _LPT1OSC_OFF_3H & _MCLRE_ON_3H
        __CONFIG    _CONFIG4L, _STVREN_ON_4L & _LVP_OFF_4L & _ICPRT_OFF_4L & _XINST_OFF_4L

Any Ideas?

I guess I need to load the bootloader....my question is, Where is the bootloader files located?

The only difference I see between your configs, and the default configs is you have two processor configs configured. I am a little surprised you got no errors. Maybe only the last one would take, I am not sure. I take it you are using internal OSC? Here is the description of each:

_FOSC_INTOSCIO_EC_1H EQU H'F8' ; Internal oscillator, port function on RA6, EC used by USB
_FOSC_INTOSC_HS_1H EQU H'FB' ; Internal oscillator, HS used by USB

Default is _FOSC_HSPLL_HS_1H (or at least that what mine is now)

As far as ICD, A bootloader has nothing to do with ICD compile. But the bootloader files are located here: C:\Program Files\Mecanique\MCSP\MCLoader\LoaderHEX

Is your program blinking the led?

[Mike2545]

Yes the program blinks the led, if I do Compile Program. It does not if I do ICD compile program
Thanks for the info on where the files are located.
I guess that I need stepped through the process of getting the bootloader file on the uC and then running the ICD.

That's funny, the PIC18F4550 wasn't on their supported list on their website (for ICD) but it is in the ICDMODELS folder. It is most likely that something is wrong with your serial connection. Maybe you could double check that.
I would not mess with a bootloader until you get the ICD running, because it could screw the ICD up.

Would it be because there is only BETA icd model available for 18F4550 and for many other unsupprted PIC's too?

Hi Gusse,

Looks like you are right.

But it looks like this page has not been updated in 4 years: http://www.mecanique.co.uk/code-stud...ICDModels.html

Or they have quite long beta testing period still going on

Hi Mike,

I tried getting your code going with internal oscillator, and had the same results at you. It would work without using ICD, but I got a communication error after I compiled for ICD. Then I tried a 20 mhz oscillator, and it did work. I modified the configs for the 20 mhz crystal. I then tried it using MCLoader bootloader, and it works as well.
