Hi Guys,
Now,i wanna to transplant the C-code generate from simulink to the Codewarrior project,but i come across some error.
Now,let me discribe my operation :
Firstly:
I opened the Model named tests564xl.mdl using simulink,and generate the C- code;
not:the file of tests564xl.mdl in the attactment.
secondly:
i built an empty project using CW;
Thirdly:
I copy the files in the folder named tests564xl_rappid_rtw to src;
shown as below:
and,there are some Errors,shown as below:
As the picture shown:
(1)How to comprehend the first warnning 'Projects can support only command file'?
(2)I cann't find the .o file,Why popup the error?
Not: My transplanting project named Test_GPIO.zip in the attachment.
Help me!
Original Attachment has been moved to: tests564xl_rappid_rtw.zip
Original Attachment has been moved to: tests564xl.mdl.zip
Original Attachment has been moved to: Test_GPIO.zip
Hi edenli,
Your approach is correct but you need to pay attention to few details.
- (1)How to comprehend the first warning 'Projects can support only one linker command file'?
Answer 1: That is because you have added 2 linker files into your project: one from the empty project creation and one from the Matlab generated code. You need to keep only one file.
Ideally would be to keep the one from Model Based design since that was used to generated and build the code.
(2)I can't find the .o file,Why popup the error?
Answer 2: No, the error says something different. It says that the "file_xxx.o" contains a symbol "YYY" and the LINKER does not know where to place it.
The *.o extension files are the outputs of the compilation stage - machine code but with unresolved address for the symbols.
The LINKER takes all these *.o file that are the outcome of *.c files and tries to resolve all the symbols based on the linker command file that basically tells the LINKER in which memory section to place your function/variable/code/data etc (aka symbols)
You need to fix the #1 problem first and choose the correct linker command file for compilation.
Hope this helps!
Daniel
PS: one of these days i'm going to create a video about how to create a CW project from files generated by Model Based Design - since i see is a hot topic.
