printf("%c".. not working on CW v7.1.2, CF V2 (52259evb)

[audiodane]

Hello everyone..

Building with codewarrior v7.1.2 for the V2 family, specifically using the MCF52259 chip...

For simplicity, I am redirecting printf(...) to an AsynchroSerial module (AS1).  I am NOT using the internal console, but an external VT100 terminal interface for stdout.

The following code segment:

char UartChar = 'D';printf("%c", UartChar);

does nothing.  Following things through down through the debug process, I come across this snippet within printf_tiny_IO.c (line 460, file revision 1.5.2.2):

#if LIBDEF_PRINTF_CHAR        case 'c': /* char */          c1 = (char)va_arg(args, int);          str = (char *) &c1;          len = 1;          goto string; /*lint !e801 Use of goto is not deprecated */#endif

The line is not compiled into the project (no dots on the left hand side to place debug breakpoints).

I have tried adding the following to the project "C/C++ Preprocessor ---> Prefix Text" box:

#define LIBDEF_PRINTF_CHAR 1

But that does not seem to help the way I expect it should-- the code snippet above is STILL ignored, and I can find no higher-level #if condition that is missing..   Am I mis-understanding how to set this parameter in the v7.1.2 codewarrior tool?

thanks,

..dane

Hello

The point here is that the function printf is taken from the library, so building the project with #define LIBDEF_PRINTF_CHAR 1 will not help here.

You have 2 solutions here:

  1- Rebuild the library with #define LIBDEF_PRINTF_CHAR 1

  2- Add the file printf_tiny_IO.c to your project and rebuild the project. Make sure the file printf_tiny_IO.c  comes before the MSL library in the project link order tab.

I hope this helps

I have also tried your suggestion to rebuild the libraries, but don't know how.  I found an earlier post that seems to apply to an earlier version of the tools.  those paths don't exist with my CW v7.1.2 installation.

I would love to include the appropriate files locally so that it works without having to rebuild libraries on all my coworkers machines, though.  But at this point, I'm open to anything...

thanks,

Hello

Can you check in your application .map file where the vprintf function is taken from?

CrasyCat

[audiodane]

Ahhh..    I found the .xMAP file (not .map) that shows the vprintf() routine coming from C_4i_CF_SZ_MSL.a.     I just don't know what project that build is located in ..

And now it turns out I need the %x supported also...   so %c and %x support are both needed.   Again, I'm open to rebuilding the libraries if I need to, but it would be much simpler if somehow I could do an "override" within my project that all other team members could more easily duplicate.

thanks!!!

Hello

I have no clue why the override is not working for you.

If you want to get this one investigated, I would recommend you to submit a service request for that.

Click here to submit a service request.

Make sure to attach a reproducible project and installed product information to the service request.
To generate the required information:
- Start CodeWarrior
- Open the project
- Select "Help" -> "Pack and Go" and follow instructions on the screen.

Attach the generated .zip file to the SR.

In order to rebuild the library:

  - In CodeWarrior open the file {Install}\ColdFire_Support\msl\MSL_C\MSL_ColdFire\Project\MSL_C.CF.SZ.mcp
  - Select build target 4i ColdFire SZ

  - Apply the changes in the Project settings

  - Build the project. This should generate a new .a file.

Working on the service request now.  Thank you.

Also, I was able to recompile the library just fine-- thank you!!   While this is a good interim fix, I do look forward to undersatnding the "better" fix soon from the SR..

[audiodane]

Service ticket told me how to utilize the full library support.  That increased code size by 300% (3x).  (yikes!)   But it still had problems compiling, telling me I needed to implement InitializeUART, ReadUART, and WriteUART functions, which I never had to do with the SZ library.

Given those two issues (3x code-size increase and additional function definition requirements), I decided to revert back to a custom-compiled library.  And to make it easier on other team players, I am going to copy the library files into a project subfolder ({Project}\Lib\Src).  That way we're using the same library across the board, and it's archived in case something changes down the road (compiler upgrade, etc).

Cheers,

Hello

Just an additional side note here.

Can you try to add the module printf.c (instead of printf_tiny_IO.c) in your project.

Make sure this file is above the MSL library file in the link order tab and then rebuild the project.

This might fix the override problem you are seeing.

I like the idea of having something locally handled (like option 2) so that others on the team have less manual library rebuilding to do...  However, it doesn't seem to be working.

I have attached my link order view.  You can see the printf_tiny_IO.c file is listed fourth from the top, before anything else.  I can Project -> Remove Object Code -> All Projects and a red checkmark shows to its left.  But when I invoke Make, the red check goes away but the Code and Data columns still show "0" for the pritnf_tiny_IO.c file, and when I go to debug, those lines are still left out.

I have also included the C/C++ preprocessor snapshot here as well.

Any pointers to what I'm doing wrong would be wonderful..

thanks,
