    Juan Gonzales
    This is great news! At least we know who has a Blackhawk emulator now. :) I also want to highlight (mentioned in original post) the fact that Specturm Digital drivers include a ready-to run DM6467 EVM configuration, no need to create your own using AMR926 and C64X+.

    This issue is actually shown as a constraint as opposed to a known bug in the manual which unfortunately makes it sound like it may not be fixed, if it will or not I could not say for certain. The issue actually sounds like a similar issue that was common with the DM642 video ports where the DMA would...

    3 msec sounds quite long to process an IOCTL; in other products (and probably on this one as well), we use IOCTL (XXXX_WAIT_FOR_VSYNC) for each frame of video which means they are being processed faster than 33msec. I would investigate the driver source code a bit further, try returning right away...

    Juan Gonzales
    Many of our DaVinci (DM355, DM6467, DM644X) boards are built by Spectrum Digital(SD). Therefore, if you suspect there is a problem with the EVM, you should do due digleence to try and verify the suspected problem area (there are normally board level tests posted on SD Website). If you still feel there...

    Apologies, I meant 3 sec. In my previous post, I suggested you modify the code to return from the IOCTL call right away to confirm it is not the call from user space to kernel space that is taking long, but perhaps the implementation that processes that particular ioctl. I can tell you for sure that...

    The DM6467 Getting Started Guide (spruf88a.pdf) has information on properly setting up the remote control unit (RCU) to work with DM6467 EVM. This is also true of corresponding Getting Started Guides for other DaVinci processors.

    Hi Brijesh, Thanks for the explanation. So if getinput is not suppossed to be called in a loop the question remains then how does one detect that the input is unplugged "programatically". To make IOCTL calls to STREAMOFF and STREAMON the program will need to know that the input is unplugged...

    Thanks for the suggestion. I have tried with checking the signal on a periodic basis and reseting the video input upon detection of no signal, but as i am running an Computer vision algorithm on the captured image the algorithm changes its model causing it to behave wierdly. Although upon reset of the...

    Juan Gonzales
    The features and limitations of the USB driver are detailed in the PSP release notes (e.g. ReleaseNotes_DM646x_Linux_PSP.pdf) which are included as part of the DVSDK. I believe the limitation in the number of devices that can be supported are based on the types of devices; certain devices use an entire...

    are all 10 devices interrupt-type devices? I think you can implement a software arbiter to manage the end-points; I do not know how difficult this would be though.

  • Forum Post: Re: DM6467 arm968 boot

    Juan Gonzales
    I am not sure I understand the question. Codec Engine framework is software layer that runs on both ARM (at user level) and DSP. In ARM side, the kernel has to load before any user level application; booting ARM requires boot-loader (e.g. u-boot) and Linux Kernel (uImage), both which are provided with...

  • Forum Post: Re: DM6467 arm968 boot

    Daniel Allred
    The arm968 cores in the DM6467 are part of the accelerator blocks that are used by the codecs. In general, these aren't parts of the system that you would want to load with your own code, particularly if you are planning on using the codec engine framework. Codecs that make use of the accelerators...

  • Forum Post: Re: DM6467 arm968 boot

    Bernie Thompson TI
    In general as a DM6467 user you should not be concerned with the ARM968, the use of this core is beyond the scope of what we typically support on the device. The only case where you would be dealing with booting the ARM968 is if you were a third party codec developer, which is a limited group who would...

    Good morning, We are evaluating a dm6467 EVM for graphical applications and HD video processing. The EVM comes with an X server for a frame buffer device (/dev/fb/...), which it cannot find. The davinci kernel drivers only seem to support fbdev on dm355 and dm644x. What is the supported route for running...

    Oliver, The video display driver on DM6467 is based on V4L2 (as opposed to frame buffer as in DM644x) Linux standard. I am not sure if X Server can run on top of V4L2; otherwise, you may need to port a frame-buffer driver to DM6467. Please note that from a hardware perspective, display hardware on...

    Are you working with DVSDK 1_40_00_31? it looks like all the versions you listed above (for codec and your work environment) match this DVSDK release. If so can you build the dm6467_dvsdk_combos_1_15 directory, this should include the MPEG2 decoder. If you can build this, then at least we will know...

    Interesting, I just checked and you are correct, the mpeg2 libs are not there. Where did you get the evaluation codec? Did you only get the mpeg2dec codec (which means you will need to modify files to omit the other codecs before attempting to build combo)? I have build these dsp servers in the past...

    I decided to pursue the earlier idea of dumping out the RMAN tables. With a few lines of code on the DSP, I found the tables to be empty, which explains the error message. After reviewing every source file, I found that the <server>.cfg file included the EDMA3 and HDVICP modules, but that they...
