    TimHarron
    Which version of the DM642 EVM do you have? Basically what I am looking for is what type of video decoder your EVM has (either 2x Philips SAA7115 or 1x TI TVP5146). Let me know your email address (feel free to send to me in a private message).

    Unfortunately I don't think this is posted anywhere publicly, but if you need a copy feel free to contact TI through http://support.ti.com and someone should be able to get it to you (as opposed to everyone who needs it from here on out PMing Tim :) ).

    TimHarron
    Are you using the DM642 Video Port Mini-Driver in addition to the UART driver for the DM642 EVM? There was a problem in the VPMD which overwrites a few registers in the EVM's FPGA which essentially disables the UART. This is a simple fix, so if you are in fact using the VPMD and UART drivers I will...

    There are four hard register writes into FPGA registers that should be modified. I'll quote the code changes I made. Look for the comments with my initials. static void configSAA7105(SAA7105_Mode videoMode, Bool slaveModeEnable, SAA7105_AnalogFormat outMode, SAA7105_InputFormat inFormat, Bool enableBT656Sync...

    Hi TimHarron, Unfortunately that doesn't seem to work, or do anything different for that matter. I forgot to mention yesterday that the program (both original & modified) runs for only a few seconds. It then halts with the message: s/w breakpoint. Another thing is that, sometimes, when I load...

    As it is crashing like this, it could be that your stack or heap sizes are too small, particularly if you are allocating additional large arrays beyond what the driver is allocating. I would make sure that the arrays you are processing are declared as global so they can be statically allocated, if they...

    Bernie Thompson TI
    I am glad to hear that making the arrays global fixed the crashing issue. As to being slow do you mean just the lag as in a delay/latency from the video input to the video output or do you mean that you are dropping frames? In either case it is possible that you are reaching performance limits of the...

    By slow I mean that when I put my hand in front of the camera, there is a 2,3-second delay before it is displayed. And I guess there are also lost frames, as my hand seems to 'magically' appear in front of the camera. I hope I'm not reaching the performance limit of the DM642, this is just...

    Hi, I am trying to fill holes in an object. The theory is if the current pixel is 0 (black), the pixel to the left (previous column) is 1 (white) and the pixel above (previous row) is 1, then the current pixel value should be changed to 1. I implemented that with the following program, but it returns...
