FILE I/O in CCS v4

Pallab Maji

Hello everyone,

I am a newbie to CCS and working with CCS v4 and TMS320C6713. I want to know how can I perform FILE operations using functions like fopen(), fclose(), etc? I want to execute a prog and want to write the results in file.txt. I have written a code for this which runs fine in a C compiler. However the code does not create any file when I run it on my target DSP.

Any document regarding this will be of immense help.

Please help.

Thanks and regards,

Pallab.

Pallab,

Two wiki pages discuss theoretical and practical details of CIO implementation by our compiler tools. Please check them and see if they are helpful:

http://processors.wiki.ti.com/index.php/Tips_for_using_printf

http://processors.wiki.ti.com/index.php/Printf_support_in_compiler

Another detail regarding the file creation is the operating system itself. For example, if you are using Linux, Windows Vista/7, the file may or may not be created depending on the permissions of the destination directory.

Hope this helps,

Rafael

P.S. Please refrain from revamping very old threads (as in your other post). Instead, please add a link or a reference to it in your new thread. Thank you!

Thanks Rafael,

I went through the documents. I have sorted the problem out however. It was because of my stack and heap size.

Thank you very much for the documents.
