CCS: CToolsLib Examples problem.

Tool/software: Code Composer Studio

Hi, All.

I'm working on the Embedded Trace Buffers of the C6678 ( I use the EVM6678-Board with mezzanine).

I try to run the example project exTIETB-EDMA_C6678 from (https://gforge.ti.com/gf/project/ctoolslib/frs Examples_5.9.zip) .

It run well, but fopen() not work (file descriptor = 0) , although printf on console is working and ,I think so , the CIO is proper.

What can be my problem?

Thank on advance,

Leon.

Leon,

fopen() returning zero may indicate a series of problems, ranging from the file being inaccessible up to insufficient heap.

I would double check the destination file/directory (set by default to C:\temp) and see if a file can be created there.

If that place is accessible, I would then try to increase the heap in your project.

Additional details about CIO operations are shown at:

Hope this helps,
Rafael
