EVM example on Beagle Bone

Sebastian Herrmann
Prodigy 155 points

Hello everyone

I want to use the McASP interface on a Beagle Bone Board. I am using Code Composer Studio v5

For this reason I was trying to modify the EVM example "mcaspPlayBk". I tried to change mcasp.c which is used in the project. But this had no effect.

I guess all functions of this and other files are deposited in libraries like platform.lib. But I was not able to modify these libraries.

Is there a way to do this?

Thanks a lot

    Hi,

         As far as i know McASP is not exposed on beaglebone board.

         mcasp.c is a driver file. you need to compile the drivers project for the change to this file to take effect.

          The dependent projects (drivers, system_config, platform, utils) need to be compiled before compiling the application project.

    Hi Sebastian,

    McASP interface is not supported on Beagle Bone Board. As a starting point, We suggest you can start with UART example application. For this, as Baskaran explained, you can build the dependent libraries first, then the example application. Then you can modify the example according to your requirement.

    All the CCSv5 projects are present in /build folder. The UART echo for beaglebone is present in /build/armv7a/cgttms470_ccs/am335x/beaglebone.

    The user guides for StarterWare is provided with the package (/docs folder). You will be able to see further details in the user guide.

    Regards,

    Sujith.

    Hi,

    I wan to Stream the Wave file Audio from ALSA(aplay) over McASP0 lines.Can you please suggest me how shall I start ? I am using Beaglebone Rev3.

    I am interfacing the Beaglebone MCASP lines to NUVOTON Sound card chip I2S lines.Here I need to use I2S data lines only.

    NUVOTON chip programmig is done by other Microcontroller chip control interface(Not Beaglebone).

    I want to stream the Audio data over these lines.NUVOTON is the master and supplies FS clock(8KHz) and Bit clock(256KHz) always.

    Info :

    MCASP0 lines : LCD_DATA8.mcasp0_aclkx,LCD_DATA9.mcasp0_fsx,LCD_DATA12.mcasp0_axr2,LCD_DATA12.mcasp0_axr13

     

    Thanks.
