    SI, To check for the patch download correctly, you can read the RAM Version (register 05h) and RAM Test Version (register 06h). For example, if the patch is 02.01.17, you should get 01 for register 05h and 17h for 06h. We will try the sync loss in lab. Regards, Viet

The frame rate is 30 fps and cannot downsize to 15 fps. The backend has to drop a frame in every 2 frames in demux the metadata. Hope...

    Thanks, Viet. Were you able to confirm that the OMAP3530 could demultiplex the lines or pixels as would be required for this to work? Thanks again, Chris

    Hello Chris, I cannot confirm this since I am not familiar with OMAP3530. But there is a forum on OMAP3530 that you can post. It is at: http://e2e.ti.com/support/arm174_microprocessors/omap_applications_processors/f/42.aspx Regards, Viet

    Viet, Thanks for your test and feedback. I think no more action is needed. I confirmed ITX did not update our latest patch yet, and this sync lost problem is related with this patch - sync lost at low level input. ITX found the input level would be lower when a bright light is shined in IR camera...

    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...

    Hello Viet, I am developing a system with TVP5158 and DM365 processor. I am using DVSDK3.10 for my system. Does this driver work with DVSDK 3.10 and Arago Linux kernel 2.6.32-rc2? Regards, Suhas Jain

    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

    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
