ERROR: RUN PLACEMENT FAILS FOR OBJECT .bss, .cio and .stack

Thanks for your quick response, I've rerouted the fputc() and fputs() functions in the same way indicated in http://processors.wiki.ti.com/index.php/Printf_support_for_MSP430_CCSTUDIO_compiler and the code errors have dissapear. But now I´ve some more doubts:

-  what is the function of register FILE *_fp?

int fputc(int _c, register FILE *_fp)
{
while(!(UCA0TXIFG & IFG2));
UCA0TXBUF = (unsigned char) _c;

return((unsigned char)_c);
}

- What does the fputs function? What does it charges to UCA0TXBUF?

int fputs(const char *_ptr, register FILE *_fp)
{
unsigned int i, len;

len = strlen(_ptr);

for(i=0 ; i<len ; i++)
{
while(!(UCA0TXIFG & IFG2));
UCA0TXBUF = (unsigned char) _ptr[i];
}

return len;
}

- Is there any way to kow how many RAM I´ve left?

Thanks in advance, Biara

Hi,

The register FILE *_fp parameter does not have any function in the modified functions for the MSP430. It is required in the modified runtime library functions to maintain compatibility with the existing header files - otherwise the compiler would throw errors if the prototype (in the header file) and the function (in your source file) do not match.

The fputs function prints a string instead of a single character of fputc.

The amount of static RAM available (i.e., allocated by the linker) is available in the linker map file. In your CCS project, open the output subdirectory (typically Debug or Release) and double-click on the file with the .map extension. It reports the memory sections together with usage.

Hope this helps,

Rafael

Thanks for your reply again.

I've followed your instructions and I've gotten this memory configuration:

  RESET                 0000fffe       0000ffff  00000000  0000ffff

Why doesn't it shows RAM and the others names?

In this last project I've obteined this warnings:

creating output section ".int06" without a SECTIONS specification (and the same for the .int07, .int13, .restet and stack. files). I've searched in the forum about this warnings and in this thread http://e2e.ti.com/support/development_tools/code_composer_studio/f/81/p/199685/710628.aspx#710628 say: It is advisable to update the linker command file and add these sections to the SECTIONS specification. ¿How can I do that?

Thanks in advance, Biara

I realizaed that the .cmd file in my second project didn't have specified the system memory map and also the sections. Then now I'm using the file of the first project. Is it correct?

Hi,

From what you posted (the error messages and the contents of the two map files) it seems the first linker CMD file is more complete. I would use it.

Cheers,

Rafael

CCS comes installed with many example linker command files for MSP430.  You can find things like ...

install_root/ccs_base/msp430/include/msp430x461x1.cmd

I suggest you use the one for your target system.

Thanks and regards,

Thanks, then the file lnk_msp430f2252.cmd is the only file with .cmd extension that must contain the project carpet?

Yes, that is correct.
