hi, I am trying to perform data I/O using the Codec AD535 for DSK 6711 with CCS 2.0. While my aim is to receive a sin wave on J7 and process it to J6 DAC, Currently i have generated the wave via code (from http://www.ee.ic.ac.uk/pcheung/teaching/ee3_Study_Project/lab3.pdf). Although DSP/BIOS config file is used but no interrupts are enabled. I am getting the error message undefined first referenced symbol in file --------- ---------------- _CSL6711_LIB_ C:\ti\myprojects\rt_dataout\Debug\rt_dataout.obj >> error: symbol referencing errors - ./Debug/rt_dataout.out not built Build Complete, 1 Errors, 0 Warnings, 0 Remarks. I'll appreciate if some one can indicate the possible source of fault.

Hi Fahim, You have defined your target configuration i.e. C6711 and also defined it in your preprocessor. But you haven't added csl6711.lib from \\ti\c6000\bios\lib . Add this to your project and it should run smoothly. The source of problem is CSL_init().

have you included csl6711.lib file in your project...? Add it by clicking Project->add files to project and browse where this file is kept and add to your project and built again.
