Still having problems with # org

[shital]

I am using the bootloader and Quick Programmer P1618QP to download a c file for 18F6621 pic microcontroller. The boot block is from 0x0000 to 0x0800. I want to start my main at 800h and my interrupt code at 808h and 818h. The reset vector can be at 0.

I tried using #ORG 0x800, getenv("PROGRAM_MEMORY")-1 DEFAULT
before main but the compiler gives me the following error messages.

-- Info 300 "C:\V3\test.c" Line 4018(40,41): More info: Segment at 00000-0FBFE (0000 used)
--- Info 300 "C:\V3\test.c" Line 4018(40,41): More info: Segment at 0FC00-0FC1E (0000 used) Priv

*** Error 126 "C:\V3\test.c" Line 4018(40,41): Invalid ORG range

I tried using a start addr and end addr and used # org like it is used in bootloader.c

#org 0x40,0x7F
void main(void)
{
if(!input(PIN_B5))
load_program();
}

#org default
void load_program(void)
{
int i;
i = 1;
return;
}

but I still get an error message as follows when I try to compile.

main
Seg 00040-0007E, 0040 left, need 00CC
0000
*** Error 71 "C:\trial\test.c" Line 4148(0,1): Out of ROM, A segment or the program is too large. I tried increasing the org range but i still get the same error. Please help and Thank You in advance

The reason you are getting errors in the top syntax (which is the correct one), is that you have ICD enabled, and this requires space at the top of memory. You need to exclude the area used for the ICD. In your case it looks as if the stuff starts at 0FBFE. So you would need to use:

#ORG 0x800, getenv("PROGRAM_MEMORY")-0x401 DEFAULT

You are missing a lot of the org controls from bootloader. If you study what is being done, it always loads the 'bootloader.h' file, which assigns the space for the bootloader, then assigns the main code beyond this. You need to look at th complete code, not just the stuff in main.

Thank you very much .
The solution worked when I dont use delay routines and interrupts.
I am still trying to figure out how to change that so that there is no code above 800h. Also since my code is very long I am trying to use different # org for all the functions so that it is not out of a ROM page.

" I am using an 18F6520. In the INI file, I changed (pmrangelow="000800"). The C init module I changed to (#pragma code _entry_scn=0x000800). "

I found this quote in an old message in a different forum. But when I tried to use # pragma the compiler gave me an error message . Can someone plz tell me how to use # pragma in this context

You need to read the CCS manual. The statement you posted is for the Microchip C18 compiler. It will not work with CCS.

[Guest]

Thank you for making me aware

Is there a statement in CCS C compiler which can be used in a similar way?

[Mark]

For one, you should register. Its too confusing to know who guest is.

The program that you have listed is for the Microchip Bootloader. I am not aware of anyone who has ported it to CCS.

The similar statements are #build and #org

[shital]

I am using #ORG 0x800, getenv("PROGRAM_MEMORY")-0x401 DEFAULT
as suggested on this forum ( and I am really grateful for that).

It works well for a small code. But when I try to use it for my actual code
I get this error message.

Error 71 "C:\Software\TX3 Code\Transmitter 3.c" Line 4129(0,1): Out of ROM, A segment or the program is too large
Halting build on first failure as requested.
BUILD FAILED: Fri Jul 22 13:48:33 2005

So I am trying to give several different ORG range for the functions before main. But I get error messages again.

Something like

Error 126 "C:\Software\TX3 Code\Transmitter 3.c" Line 181(21,22): Invalid ORG range
--- Info 300 "C:\Software\TX3 Code\Transmitter 3.c" Line 191(21,22): More info: Segment at 00000-0FBFE (0000 used)

*** Error 126 "C:\Software\TX3 Code\Transmitter 3.c" Line 191(21,22): Invalid ORG range

I dont know what I am doing wrong .

All I want to do is start my code from 800h and map the interrupt vectors to 808h and 818h

I am trying to use P1618QP Quick Programmer from microchip to download the code.

Apparently it is working for me only if I start my code at 800h .
(I tested it using assembly)

I am using PIC18F6621 and added this device in the .ini file.

[DEVICELIST]

85="PIC18F6621"

[PIC18F6621]
writeblock=8
readblock=1

30000A="CONFIG6L"
30000B="CONFIG6H"
30000C="CONFIG7L"
30000D="CONFIG7H"

I assumed the Quick Programmer would load it from 800h since pmrangelow is 800. But no such luck.

Can someone plz help

How large is your program?

[shital]

The program is about 40 k long .

from 0x0000 to 0x944e

[shital]

I had made a mistake which I corrected but I am still getting this error.
I am trying to change the range and see what happens.

It is still giving me the same error messages just with different numbers needed and left.

My origin range is not greater then 0xfff at any time

Can someone tell wht is the meaning of this message
