Building MCSDK MCASP_AudioExampleProject on OMAPL138

Hi Bakir,

Thanks for your update.

McASP audio example demo should work perfectly fine since we have already tested the same from our end and we would be able to suceed indebugging the McASP example code for both pdk_OMAPL138_1_01_00_01 (mcsdk_1_01_00_01) and pdk_OMAPL138_1_01_00_02 (mcsdk_1_01_00_02).

Both the above mcsdk versions (1.1.0.1 & 1.1.0.2) of McASP audio example demo works fine with CCS version: 5.4 but there are issues with CCSv5.5 on free run or  debugging the code, i mean, after loading the application image, it runs automatically and the control doesn't come to the code for debugging and i belive, the code is freezing somewhere.

So, I would suggest you to downgrade the CCS version from 5.5 to 5.4, install and try the same demo.

Note: While launching CCS debugger, please ensure to connect the ARM core first to make DSP out of reset before running the code and disconnect the ARM core, Then try reconnecting to the DSP core, reload the application image and run the application. You will succeed in hearing the audio output through Line OUT, provided when there is some input stream (mp3, aac etc) feeded through Line IN. This is because, OMAPL138 is an ARM boot device where in which arm boots first with its bootloader code and then it wakes up the DSP core letting it out of reset, so that, we are allowed to connect to the DSP core and run the application on the same.

I would recommend you to ensure the above note is properly executed before running the McASP audio example project and you could succeed in debugging the MCSDK McASP audio example code.

Thanks & regards,

Sivaraj K
