Interfacing with the BGA chip

Other Parts Discussed in Thread: DM385

Hello. I want to create a project using the DaVinci SoC.
My original idea was to  buy a schmartboard to create pin interfaces for the chip. Though i contacted schmartboard support and they told me that BGA chips are not supported yet but will be in the future.

So what are my options now?
Is there a way to create the pcb using software, printing it somehow (if it is two layer), then do the BGA soldering on my own (i have equipment to do it manually)?

Or can i order a pcb for this chip from and online pcb manufacturer then solder the BGA chip?

Anyone interfaced with the Davinci? If yes, how you did it?

The less time consuming method is the best, as i want to get my hands on it asap!

Thanks!

    Nick,

    The DM36x requires more precise routing of DDR2 than what you'll get by hooking things up the way you are trying.  You'll have much better luck buying a leopardboard or some other pre-built board.

    What is your end goal?

    What i am trying to do is for the frist time create my own board and application. I have done work in development boards, but i dont have experience on making my own pcb, just like many commercial products do. I was always wondered on how these products got manufactured.

    My application will be a standard hook up camera, record to SD card and display on oled display. Maybe add bluetooth or WiFi to the mix thanks to components getting cheap.

    When i manage to write my application, will it be feasible to transit from development baord to my own pcb? Or, can i hire pcb manufacturers to do that?

    And what development board are there available for DM36X? It seems the DaVinci isnt very much documented.

    I checked out leopard board... Is it the only solution? What i dont really like is the camera is a HUGE pcb. There must be a way with small components too. How do cell phones or mini spy cams achieve that? Can i take these cameras and hook them up to my DaVinci through SPI or I2C?

    I want to start developing on the DaVinci ASAP... IF you provide a link for a dev board, i will buy it asap, no second thoughts

    Nick,

    I'd suggest getting your feet wet with a much smaller SoC with embedded SRAM/Flash before embarking on something as complex as the DM365/8.

    You don't want to use SPI or I2C for a camera interface.  The DM365 has a dedicated interface for cameras, see "http://www.ti.com/lit/ug/sprufg8c/sprufg8c.pdf"

    I know that there's an eval board for the DM365, but I don't see a link to actually buy it.  TI may have moved on to the DM385, such as http://www.ti.com/tool/CARDVRRDK#orderoptions.

    Best of luck!
