Original question:

Unable to use fprintf

CCS: fprintf hung up while debugging software

Tool/software: Code Composer Studio

Hi,

I'm using CCS 6.2 Compiler version 4.4.1 processor TMS320C5509A (Not using any RTOS) . I have included the standard library functions and successfully created build as well but when I try to step out of any of fprintf, fread functions debugger hung. I followed the all the steps increasing stack, heap, flushing, enabling CIO but still having the issue. Please help and thanks in advance.

    I used the same versions and fprintf works fine for me. My project used the default sizes for stack and heap (0x200 and 0x400 respectively). Please provide your example project that does not work for you.

    In regards to the hang, is the IDE GUI locked up? Are you able to shut down CCS?

    Thanks

    Thanks for your response. I wanted to write all the variable values in a file to analyze the data after execution of software. I wrote the below code snippet in the software and as soon as I reach line fprintf the debugger is not coming out of this line due to this reason the file is not closed. Yes I could able to terminate the debugging session and close the CCS without any issue.

    I did setup the stack and heap size in C5500 linker option."--stack_size=0x200 --heap_size=0x400. My project file size is huge and I have integrated the above code with the actual project not with example project. Please let me know if you are looking for any specific settings or .metadata or other files.

    Thanks,

    Ramesh

    Can you create a simple test project which simply just does an fprintf call and see if that works?
