TMS320C6655: compiler flag & linker setting

Hi Prashant,

I've forwarded this to the c66x SW experts. Their feedback should be posted here.

Prashant,

Most of the settings you have indicated in the post seem to correct but you haven`t provided the failure log that you observed when trying to build the code so it is hard to provide guidance on what is causing your build issue. Can you please provide the log.

A good starting point is always to use a CCS template to setup your code for a new architecture and then update the settings.
An example of creating a hello world template for this core is provided here:
processors.wiki.ti.com/.../Processor_SDK_Bare_Metal_Examples

You can then follow the instructions in this document to optimize the compiler and linker settings.

Hope this helps.

Hi,
Thanks for reply.
I am getting below error on cmd console.

I am moving this to the compiler forums to see if you can get some inputs from the TI compiler team experts.

You should change the linker executable to "cl6x -z" or you'll have trouble compiling C++ templates, and possibly other features.

Other than that, I'm not familiar with this configuration file, so I'll have to defer to someone else.

Hi,

     Thanks for reply.My problem is solved.Now i want to add gcov (coverage tool) with ceedling for DSP and other core.Please send me gcov excutable , gcov linker file for DSP , ARM(cortex-4),Arp32 & gcov Dsp document.
