Can't compile flowcode project in MPLab

serstel · Post by **serstel** » Thu Feb 01, 2007 6:27 pm

Hello
I output my program in an asm file using flowcode and when the process is compleded i get the following message:

Memory Usage Report
===================
RAM available:2048 bytes, used:75 bytes (3.7%), free:1973 bytes (96.3%),
Heap size:1973 bytes, Heap max single alloc:127 bytes
ROM available:32768 bytes, used:1555 bytes (4.8%), free:31213 bytes (95.2%)

However when I input the asm file into MPLab it can't build the project and I get this message:

Any idea about what the problem is?

Have you selected in mpasmwin the right type processor instead default?
I have got similar errors when the processor is wrong,or default...

if by right type processor you mean the pic 18f4550 that I use, then yes I did configure everithing for this pic.

Yes i mean...
Just think that if in mpasmwin setup the processor is default,i might ause those kind of errors..
What i had used the mpasmwin thesetup has been:radix->default,warning level -> default,hex output -> default,generated files-> error file and list file.proessor->what used,NOT default,case sensetive ->on.table size->8,macro expansion -> default and save changes on exit -> ON
Those settings the mpasmwin has worked ok...

I am not sure what you are saying but I have put in project=>build options=>project=>mpasm ->disable case sensitivity:ok and I still get the same errors.

What i ment is the mpasmwin options..
Start->Programs->Microhip->Mplabide->Mpasmwin,and there is those options.

The "18f4550i.lkr" linker file is used for debugging with the ICD2, which reserves some ROM and RAM for the ICD functionality. If you don't need ICD2 functionality, try linking with the "18f4550.lkr" file instead.

If you want to use the ICD2, try adding the following line into the "definitions" section of the "supplementary code" window of Flowcode and recompile:

Code: Select all

#include <idc2.h>

I'm not sure if this will help. If it doesn't, please post the lines in your ASM (and LST?) files that are causing the errors and someone may be able to shed some light on your problem.

Hello and sorry for all the trouble.
Unfortunatelly I failed again to build the project with MPLAB. Below are the lines from the asm file and the lkr file that are troublesome if anyone can help I would apreciate it. Thank you in advance.

I have observed that it sudenly jumps to the problematic line. As it can be seen by the segment of code before 300000 it ends at line 612. By the way the problematic code os right at the end of the program. there is nothing after it. Also I can't seem to find the instruction DW in the instruction set of the pic 18Fxxxx family.

These DW lines are (supposedly) putting the configuration word data into the PICmicro. You could delete these lines and set the configuration data manually via the appropriate MPLAB menu instead.
