  • Forum Post: What is the difference between the DM6446 and DM6467 Video input ports?

    Juan Gonzales
    DM6446 supports an 8-bit BT.656, 8-bit or 16-bit YCbCr, or up to 16-bit RAW Bayer Pattern video input. This is detailed in the DM6446 VPFE User's Guide: http://focus.ti.com/lit/ug/sprue38c/sprue38c.pdf DM6467 supports Two 8-Bit BT.656, Single 16-Bit BT.1120 (HD), or single RAW RGB 8,10 or 12-Bit...

    1) FYI, the version of DVFlasher that accompanied the App Note (spraai4) does not have support for large block NAND flash devices; if you are using one of these devices, please work from DVFlasher v1.12 available from our software update site 2) The message "S-record Decode Failed." occurs...

  • Forum Post: How do I build u-boot for NAND?

    Juan Gonzales
    Assuming you have the u-boot source code already (available from TI software update site), you will need to edit the following file .../u-boot-x.x.x/include/configs/davinci.h and set CFG_ENV_IS_IN_FLASH to 0. Then you can proceed and build u-boot as you normally would > make mrproper >...

  • Forum Post: Re: Can analog and digital video outputs on DM6446 display different images?

    Juan Gonzales
    Good point. Again, this is because there is only one video timing generator hardware block serving both analog and digital video outputs.

  • Forum Post: Re: Switch #10 of S3 doesn't work

    Bernie Thompson TI
    I am assuming you are working with a DM6446. There is a bit more to setting the board up for PAL than the S3 #10 dip switch, although it may seem that way from glancing over the documentation. This switch actually is just a pin that is checked by U-Boot, and causes U-Boot to set the environment variable...

  • Forum Post: Re: New binning or skipping mode.

    Juan Gonzales
    I am not too familiar with micron sensor driver (or hardware capabilities yet), so I cannot comment much on binning or skipping rows, but if you are going to be changing frame rates, you need to take pixel clock (aka video clock) into account. pixel clock = resolution x refresh rate By default, the...

  • Forum Post: Re: Thermal Considerations

    Bernie Thompson TI
    In most typical applications a heatsink is not necessary, it is expected that the device will get warm to the touch when powered on, even the EVM does, so I would doubt that there is something else wrong with the board. Much of the heat generated by the part ends up being soaked into the power and ground...

  • Forum Post: I need help setting up the remote control for DM6467 EVM

    Juan Gonzales
    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.

    There are various ways by which TI helps their customers get the information they need. 1) The website trainnig.ti.com contains general information of workshops offered by TI as well as free pre-recorded presentations on a variety of topics. Three popular workshops for customers new to DSP are DSP...

  • Forum Post: Re: Video processing algorithm in DSP

    Juan Gonzales
    1) For developing DSP algorithm, CCS running under windows is your best choice. At the current time, CCS does not run under Linux; this is why we only include the tool chain (compiler, linker, DSP/BIOS...) as part of DVSDK installation rather than a full blown IDE such as CCS (which includes toolchain...

  • Forum Post: Re: How to enable cache on DM6437?

    Bernie Thompson TI
    I am not sure if I entirely understand your question, however I will try to answer it. Code and data can still be read by the CPU out of external memory even if caching is disabled for the location or cache is turned off entirely within the device, however this will slow things down significantly as...

  • Forum Post: Re: A question when Booting via TFTP

    Bernie Thompson TI
    This is a strange one, but is not out of the question, a DHCP server has the ability to define a file, and it is likely that your particular router defines this with that square character, thus breaking the TFTP boot sequence. I am curious if your board ever was able to boot from TFTP? If it was able...

  • Forum Post: Re: Using the Resizer

    The App Note you referred to is exactly what I would have recommended in this circumstance. Your description of the final picture seems very odd; can you display resulting YUV file using display driver (avoid conversion to PNG) to see how it looks.

    I would recommend you read TMS320 DSP Algorithm Standard Rules and Guidelines document. http://focus.ti.com/lit/ug/spru352g/spru352g.pdf It will give you a basic understanding of the requirements imposed in your DSP algorithm's program memory (where algorithm code resides) to comply with XDAIS...

    Juan Gonzales
    Are you using static IPs (by-passing or not using router)? Based on your bootargs setting "ip=192.168.0.107" it would appear this is the case; if so, please refer to the following App Note http://focus.ti.com/dsp/docs/dspsupporttechdocsc.tsp?sectionId=3&tabId=409&familyId=1302&abstractName...

  • Forum Post: Re: question about tftp

    BrandonAzbell
    Something I find curious is the bootfile equaling /tftpboot/uImage. If your tftp server is exporting the "/" directory as the base directory, then /tftpboot/uImage should work. However, typically the tftp server is exporting /tftpboot already. In this case, the tftp client running on the...

  • Forum Post: Re: Thermal Considerations

    Juan Gonzales
    I have only seen one case (small board design) where temperature became an issue with DM6446; in this case, the work around involved redesigning the casing to help dissipte the heat. Of course, as Bernie suggested above, this is very application specific; as a general rule of thumb, the smaller the board...

    Bernie Thompson TI
    Different devices will often have different power supply sequencing requirements depending on how the internals of the device were designed to be brought up, in the case of the DM644x the core is to be brought up before the i/o however in the DM648 case as you have found the i/o is to be brought up before...

    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...

    In addition to the standard API references Juan mentioned there are some TI written documents in dvsdk_x_xx_xx_xx\PSP_xx_xx_xx_xxx\docs\dm644x that may also be of help, note that these were not available in the earlier versions of the DVSDK (so if you do not see them you may want to get a newer version...
