Part Number: OMAP-L138

Hi

I want to use mcbsp interrupt in the linux for omap.I set the mcbsp registers and it seems ok.

I did not found any example for such implementation? Does omap-l138 davinci bsp support it?

    Hi

    Thnks for the response.

    The sdk used is : ti-sdk-omapl138-lcdk-01.00.00
    linux omap version is : 3.1.10-gf6fe6d8-dirty.

    I want to update the post that I need mcbsp work with  EDMA3 and interrupt driven from the EDMA completion event.

    I found a link regards  OMAP-L1 Linux Drivers Usage which describe mcbsp test kernel object on EVM.

    Is it suitable for omap-l138 and I can base on it? 
    Is it enough?
    Is it at  DVSDK 4.xx ?


    Best Regards

    Yehuda

    Hi, 
    

    
This is quite old linux sdk, so, I think, the wiki will work for ti-sdk-omapl138-lcdk-01.00.00. 
    

    
If you wish to switch to latest TISDK (which uses kernel 4.9.28), you can refer to linux kernel documentation: 
    
  Documentation/devicetree/bindings/sound/davinci-mcbsp.txt 
    
to see how to set up the edma & irqs you want to use with MCBSP. 
    

    
Best Regards, 
    
Yordan
