    I have enabled McASP clock use ARM Linux API clk_enable(), I found the register addr from kernel API: McASP0 0x48181540 McASP1 0x48181544 McASP2 0x48181548 I set those register's 2nd bit to 1, but still can't control other register from McASP, am I set right?

    Hi all I am working with the C6A8168 EVB, and I am investigating about the EDMA usage. So I have written a DSP demo application which generate a 1Kz signal using buffers transfered by edma to MCASP2 wired to a aic306 codec. This application work fine if loaded in to the dsp by CCS5-XDS100V2, but it doesn't...

    Paolo Desii
    Hello to all, I 'm using the MCASP1 to transmit data to two DACs with success. The write port s are served by EDMA and everything works fine. Address used for XBUF0 is 0x4803C200 and for XBUF1 is 0x4803C204. Now I need to extend the architecture using the fifo of MCASP1 . To this I added MCASP1...

  • Forum Post: RE: Try to enable the 9022a for HDMI audio output

    ChengYeh Yu
    Hi, Here are two small updates, 1. McASP1 can output i2s clock after the snd_pcm_writei is called. 2. The DMA is still not working when I actually wire 9022a to McASP2 on the board. I suppose this means I need to configure 9022a to get the EDMA work? But it makes no sense to me. Any one can help...

    Hello! My goal is to use AD7887 ADC in two channels mode as sound capture device. ADC is connected to DM8168 through McASP interface pins: MCA2_AFSX -> /CS MCA2_ACLKX -> SCLK MCA2_AXR1 -> DIN MCA2_AXR0 -> DOUT This ADC works fine using SPI_MODE_2 when it is connected through SPI...
