    Hi, I have two question about tvp5158 and the mcasp of DM6467. 1) When I set reg c0h of the tvp5158 through i2c,I found set 00h(16k) and 10h(8k), the pin LRCLKR output is always 16KHz. I can readback the value of reg c0h, although it's 10h,but output LRCLKP output is 16KHz. When I set...

    For the MCASP question, can you probe and make sure there is signal coming to DavinciHD? If you don't see signal, you need to debug TVP5158

    Yes, the signal is connected to DM6467HD EVM, and the signal connections are DM6467 TVP5158 McASP0_ACLKR ---> BCLK_R(pin85) McASP0_FSR ---> LRCLK_R(pin86) McASP_AXR[0] ---> SD_R(pin88)

    I will let the TVP experts comment on this. What I meant was, when you are receiving audio, make sure you can see the signals on the AXR pins (use Oscope). Then you can worry about whether you are programming McASP right. If you don't see audio signals, debug TVP until you see the signals, and...

    Hello ZhenChang, When we test the driver, we use DSP TDM mode. We test the I2S with stand alone EVM board. Can you tell me which mode are you using on DM6467? Are you using our TVP5157/DM6467 driver code as a baseline? Regards, Viet

    I use the i2s mode, tvp5158 is master ,dm6467 is slave. I use my driver code for testing,as mcvip_test.out run error on my board. Now I can record something through tvp5158 ,but still have a question : why my tvp5158 can not output 8k sample rate?

    Hello Zhencheng, I just checked the I2S mode in the lab with the TVP5158 EVM. I got both 8Khz and 16Khz come out Ok. Can you prob the R44 (LRCLK_R audio output) on the EVM to see if it is 8Khz or 16Khz? Beside setting C0h to 02h, I also have C3h set to E0h. Regards, Viet

    Hello zchiang, Excessive noise is usually caused by the McBSP data delay being set incorrectly. Also, you can order a TVP5158 EVM at the following web site. http://focus.ti.com/docs/toolsw/folders/print/tvp5158evm.html Regards, Jim The TVP5158 audio data is delayed two BCLK...

    Hi Jerry, The patch is not required but recommended to make the TVP5158 to work perfectly since it addresses some bugs such as interrupt, QCIF mode field swap, Macrovision detection, etc... If you are running with DM6467, it is required. Regards, Viet

    Can the TVP5158 driver for DM6467 be used as a regular v4l2 driver with single channel mode? How difficult would be to modify it to work like that? Why do I need this?

    Hi Victor, The v4l2 driver does work for single channel mode since the DM6467 EVM has TVP5147 on board and it is single channel. The TVP5158 can output single channel if you setting it to bypass mode. When TVP5158 in bypass mode, it output only CH1 and the output is in BT656 format just like TVP5147...

    hi, I assume you have two TVP5158s, one connected to each of the two 8-bit ports. You need to setup the driver in 8-bit port. MCVIP_CreatePrm.videoIfMode = MCVIP_VIDEO_IF_MODE_BT656 If both driver is setup in 16-bit (BT1120) mode then only one will take effect. Note, we have tested...
