  • Forum Post: Re: USB Host controller

    Juan Gonzales
    My initial thought is that our SDK drivers (which I assume you are using) are written for the Mistral OMAP35x EVM, which only supports stereo 2-channel output. I do not believe the hardware (and probably Linux drivers) can handle 6-channels.

    Fikret Alim
    Hi, again Can this problem be related with the usage of DMA? Is the DMA used or not used in the default configurations of audioSample.pjt given inside pspdrivers. I am doubtful about this issue, because inside the mcasp channel parameter settings inside the code, "IsDmaDriven" is set as...

    Guillaume, Does the data appear different during the processing phase of your application? You may also want to try something drastic (i.e. zero out the left channel) to see if you can force any difference between the channels. Also, what did you use as the starting point for your application development...

    Tobias, The values in your data buffers should "max out" at the extreme levels input/output by the audio codec. The codec can also be configured to output or accept different data formats. For example, in 32-bit unsigned integer mode, a value of 0 corresponds to the minimum analog level...
