Hi All,
I have my custom board which have HDMI receiver chip's audio line(MCLK<-->AHCLKR,BCLK-<-->ACLKR,FSR,I2S[0-3]) is connected with DM6467 MCASP0. My HDMI chip is in Master mode so all AHCLKR, ACLKR and FSR are generated by it. I probe all the clock and data on DM6467 side and value of the clocks are as below. AHCLKR = 12.287MHz ACLKR = 3.072MHz FSR = 48KHz I can see the data on data line of MCASP0. I configure the MCASP0 as below. PDIR =0x00,RTDM =0x03, AHCLKRCTL=0x00, ACLKRCTL =0x00, RTDM =0x100 That is all clock are external and Slot size is 32 bit. I am using open source linux kernel released in 3.10 PSP. linux version is 2.6.32. It seem that all are coming to DM6467 side but my MCASP0 is not able to capture audio. There is no any EDMA interrupt in EDMA channel so it is not able to get audio data. It is giving "Input/Output error read" What can be the issue at MCASP0 side, Is there any configuration issue? Any body can help me. I appreciate you help and suggestion. Thanks Hitesh
