Error 71 ... Out of ROM, A segment or the program is too lar

[temtronic]

re: Mr. T's comment...
However on a PIC18, the memory is generally no longer paged (there are paging limitations that appear over 64K).
and this...
Seg 00188-00FFE, 006E left, need 0016A
Seg 00000-00002, 0000 left, need 0016A Reserved
Seg 00004-00006, 0004 left, need 0016A
Seg 00008-00186, 0000 left, need 0016A Reserved

I don't think 'paging' is the issue rather the entire program is just too big?
this
Seg 00188-00FFE, 006E left, need 0016A
seems to say he needs 16A words but only 6E are available

so I'm really confused.
Now I'd assume that a bigger PIC(more mem) would solve this but he says that 1/2 works... On V4 it's OK, V5, it doesn't.
still more confusion, though I suspect maybe V5 default to 'protection' high mem, some 'fuse' setting is wrong(bug ??) or something that we cannot see ,since we don't have the first 20 lines of code(fuses,etc.)
Another curious thing ,to me, is the 'Reserved' at the end of the Seg printouts. I admit I have no idea what or why they are there but I don't make a living with PICs anymore and heck if code compiles and runs, well, that's what matters.

I'm thinking were missing some crucial details.....

Light is suddenly dawning.....

He talks about the 18F2220, yet the listing shows 2K.
The 'new' version he has got is the demo compiler, not he full copy of CCS. Limited to 2K program size.

Duh....

[Jean FOUGERON]

Thanks for your help Ttelmah and Temtronic
I now can compile when I have suppressed all my JBus fuctions !
(but I need them)
Anyway, when I modify my code somewhere else, I get the error again.

Now, when I type a character, I wonder wether it will produce an error 71 or not. It is very unconfortable !!!

For example this code works

As Ttelmah commented, stop using the demo version of the compiler. Get the full version.

[Jean FOUGERON]

Sorry
I don't understand
I use the same version V4 I always used bought to CCS, and my pch.crg is dated 07/01/2013

How can I see that I have a demo version and not a full version, and why would I have a demo version and not a full one ?

[temtronic]

this...

....

This now makes 100% sense as to WHY you're running into the 'problem'. You're at the LIMIT of the compiler version(demo) that you are using. You can't put size 12 feet into size 7 shoes ! Well, not easily!!

So now you have 2 and only two options

1) buy the real compiler from CCS. That way you will NOT have a 'memory' problem.

2) get very,very 'creative' in code cutting. In the good old days you HAD to be creative and could get a HUGE program into a small space.

Option 1 is probably your best choice as it gets you 'up and running' for a few bucks.
Option 2 will force you to become a pretty good code cutter but could take months in not years.

[temtronic]

silly question...
did you previously download the 'demo' version ?

If so, then I assume your PC is going to it to run the compiler. That would explain the 2K limit.

Since you bought a complete version, I suggest you uninstall the 'demo', then install the one CCS supplied, following their instructions.

[dyeatman]

To answer your earlier question, the version is shown at
the top of the .LST file. If it has a "d" on the end of the
version it is a demo...

i.e. CCS PCM C Compiler, Version 5.032d

You are missing the point.

You were complaining that V5 on a different workstation, would not compile the code, but V4 did. That you got the 'out of memory' error with V5.
The posting you made of the error from V5, shows that the V5 compiler you are running is either the demo version, or you have an org statement in your code restricting the memory space it can use, which is why _it_ complained about the memory size.
The V4 compiler was a full version, so didn't.

[Jean FOUGERON]

I compiled my project in 2013 with V4 version and it worked
As customer asks for changes, we have made pcb changes and need to adapt software for it..
So, when I have tried to compile with these modifications, I before updated to V5.
I had Error 71 and then posted here.
Thinking V5 had a problem, I came back to V4, normally as it worked in 2013 it has to work now !
No : Error 71

And then you explain me that I surely own a demo version.

I look at .lst file (as told by dyeatman) and see I have a full V4 version

[temtronic]

this....
ROM used: 4068 bytes (99%)
Largest free fragment is 28


tells me you've run out of memory space !!
Out of 4096 possible locations ALL but 28 are used.

You need to upgrade to a PIC with more program memory. I typically use the 18F46K22 which has 64K of memory so I've never run out.Hopefully there's a PIC in the same 'family' that is pin compatible,with same peripherals.

The key thing to do, is to compile something short with V5. A one line test program. This then will display the version number being used.

Also if you have ever installed the test version, 'step back'. Un-install this, and the existing V5, Make sure the PICC directories are removed, and then do a clean install of V5.

Point is that every chip you refer to has a larger memory size than in being actually displayed. Similarly you mentioned at one point switching to a 16K chip, and getting the same result. The error printout, shows the compiler limiting the compile size to the 2K limit associated with the demo version, so it is all behaving as if (somehow) it thinks you have this....
If you downloaded the latest version, are you sure you went to the 'downloads', 'compiler updates', not 'compiler demo'?. The tabs are next to one another.

[Jean FOUGERON]

Thanks to all of you
I inserted a PIC18F2520 which is 16k and it runs (with V4)



as soon I have time, I try with V5

But first, finish the project and deliver to customer

Have a good WE, expecting nothing else appears
