Hi Ron and Rene,
thanks for your help. I send the problem as bug re****t to Metrowerks
already. During my efforts to find a solution for that another error
occurred.
First of all I describe further my project and several back ground
information like the involving processor.
I use the s12db128 microcontroller from Motorola for an automotive
control device with two CAN interfaces and one SCI interface. To say it
simple the controller should be a gateway between the three interfaces.
I developed the program with the Metrowerks Compiler for HCS12
processors (CWS-HC12-STDED-CX - compiler version 5.021 - smartlinker
version 5.0.17). I transferred the generated code with a Lauterbach
debugger to my target (Power Debug Interface / USB 2 with a BDM-MCS12
interface) and everything worked fine.
Now I supervise the same project but for an other employer. The project
has several amplifications, so I wanted to transfer only the existing
code first. The only difference is that I have a newer version of the
Codewarrior (CWS-HC12-STDED-CX - compiler version 5.024 - smartlinker
version 5.0.22). The Lauterbach debugger is the same. I didn't change
the code to that point and I got the following link errors:
Error L1907: Fixup overflow in OSEKOSVectorTable, to Can2TxInterrupt
type 1, at offset 0x28
Error L1907: Fixup overflow in OSEKOSVectorTable, to Can2RxInterrupt
type 1, at offset 0x2A
Also the parameter of the compiler and linker are the same. (The
project is organize with a gnu makefile)
CHC12.exe -Cc -Mb -F2 -DCRYPTO_AUTH_$(CRYPTO_AUTH)
-DCRYPTO_SIG_$(CRYPTO_SIG) "-ObjN=$(OBJ_PATH)\%n.o" -WmsgSd110 -Os
linker.exe "-ENVOBJPATH=$(OBJ_PATH); $(HICROSS)/lib/Hc12C/lib" -B
$(OBJ_PATH)/template.prm
The first possible error which you wrote Rene can't be the reason
because the makefile always delete the old object files before the
compiler starts.
To the second point I describe more about my program. I use the OSEK
operating system and for that it is common to apply the attributes of
the operating system in an oil file. All interrupts, tasks and so on
are described in this file. The OSEK configurator generates out of it
several .h and .c files like os.h and os.c. The interrupt
Can2RxInterupt and the OSEKOSVectorTable are both in os.c. The
OSEKOSVectorTable contains all interrupt sources of the controller. All
interrupts are defined as extern so you can react for these events in
our own c-files. In my case the problematic c-file is the subcan.c
(Can2TxInterrupt and Can2RxInterrupt are in this file)
After I added another interrupt source like Can2ErrorInterrupt the
linker shows me another error:
Error L1907: Fixup overflow in OSEKOSVectorTable, to Can2TxInterrupt
type 1, at offset 0x2C
So on I deleted all interrupt definitions in the subcan.c file and
moved them in another own (applmain.c). The compiler and linker
generate the project without errors and warnings. And here comes the
second error back to game. After the code generation I transferred it
with the Lauterbach debugger to my target. But the program counter
jumps always in the memory area for variables and nothing works. This
have nothing to do with the displacement of both interrupts because I
have the same result if I disable these interrupts.
I hope you can help me because I have to show the function of my
program in the next week. Thanks
Yours sincerely,
Thomas
