Starting up with DM355

Hi,

I would like to quickly start up with DM355 Development. I am actually interested in VPFE interfacing with CMOS Camera Sensor! I have seen a lot of dokumentation and kind of confused about them. So, could somebody show me relevant Docs and Software tools so that I could read and start Developing. And, also could somebody recommend me relvant SDRAM for DM355 (I have read that it should fit to JESD79D-2A standard, but could not understand this)... And please, give some guidelines to Software toolchains.
Regards

    Hi Shuhrat,

    I'll try to answer some of the questions. First of all, I hope you're aware that DM355 is a fairly old device and support will be difficult to obtain in case of issues, etc. The DM365 and DM368 are newer evolution of the DM355 design and you should look into those too.

    What exactly is your application? What video codec do you plan to use (assuming video application)? 

    Obviously, you should start off reading this http://processors.wiki.ti.com/index.php/DM355_Getting_Started_Guide

    The DVSDK with it's documentation is available at http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/dvsdk/DVSDK_3_10/latest/index_FDS.html There are links to all the tools you'll need for linux based development.

    Regards,

    Hi Akshay

    Thanks for replying to my post!

    Well, what I need is just to process raw data from CMOS sensor, convert to Video and transmit the video stream through WiFi to some other station where the video can be displayed on screen. I have chosen dm355 because of low cost(Farnel Price 14 EUR against 28 EUR for dm365),

    I've already read through Getting Started and even installed all the needed tools on Ubuntu, I've installed GCC(codesourcery) dvsd3.10, linuxdavincistaging and linuxlibs, I have also built Linux kernel for dm355 and everything what is needed I have done!! Right now I have a lot of files in my system and a kind of confused about them, so I am asking smbdy to explain me how to get started with these development tools??

    Regards

    Shuhrat

    Hi Shuhrat,

    Which CMOS sensor have you chosen? If you're using a CMOS sensor which the DVSDK is compatible with, then perhaps you could try running some of the demo applications that are present in the package. (assuming you have the hardware available with you). 

    If you have access to something like a Leopard Board 355, perhaps you can experiment with the IPNC application which will capture, encode and transmit video over Ethernet.

    Hi Akshay

    I am considering Micron Image sensor MT9T031 as proposed in Linux drivers manual.. I have no hardware yet, I am still considering if it is worth using Devices from TI. I need low cost Powerful devices with OpenSource Support. And, which SDRAM could you recommend??

    Regards

    Hi

    I tried to find leopardboard 355 for buying but there is only 365 or other boards offered!! Could someone show link for 355, or is it not offered any more??

    Shuhrat,

    Have you checked DM355 IPNC reference design from Kane Computing as well as Zot, Appro?
