dsp / arm cio support

Other Parts Discussed in Thread: OMAPL138

Hi, I am looking to compile a cross platform program to run on the dsp chip of an OMAPL138 LCDK.

The program requires access to stdout, and to print to files using the normal fopen(), fprintf() c library functionality. I read in the SPRU187U.pdf document, included with the cl6x compiler, that cio functions are supported (pg 250), and that a 'debugger' and an 'appropriate driver' are required to be running on the host system.

Could you please direct me to documentation or examples of this functionality in action? I would assume for the LCDK/OMAPL138 systems that there would be the appropriate drivers/debuggers available, but I have not been able to locate them through google, the ti website, the doc, or the ti wiki.

Thanks

Hi,

Thanks for your post.

The better document source would be the c6000 optimizing compiler user guide as below, in which kindly refer section 8.2 for the C I/O functions and refer section 8.2.3 for device driver level I/O functions:

http://www.ti.com/lit/ug/spru187v/spru187v.pdf

Also, Kindly refer the wiki tips for using printf:

http://processors.wiki.ti.com/index.php/Tips_for_using_printf#Low-level_I.2FO_functions

May be, you could refer the below E2E post for the LED test code:

For further follow-up's, you could post your query on CIO functions to TI C/C++ compiler forum which would be better answered and we could only support to our limited scope on CIO function related queries

Thanks for your understanding.

Regards,

Sivaraj K
