Defect during production?

Other Parts Discussed in Thread: AM1808, OMAP-L138

Hi,

We bought a Hawkboard to be the prototype of our AM1808 board, which use an OMAP-L138(which is pin to pin compatible with AM1808) ,  unfortunately, it have problem and they said it would be ok if have XOMAP-L138 soldered on, here is the link: http://elinux.org/Hawkboard_problem

So, below are my questions:

1. Iis this because of some defect during production?

2. Does AM1808 have same problem? 

3. Have this problem been solved?

4. How to know we are buying chips without defect?

Thanks.

    As it says on the webpage you referenced:

    "HawkBoard.org and TI are investigating the situation in more detail and will work with you to ensure all faulty boards are fixed. We will post periodic updates on this mailing list as we work to resolve the issue."

    When the answers to your questions are known, you will receive the updates through having registered your situation on that webpage.

    Thanks for your quick response, RandyP.

    I'd registered on that webpage.

    One difference is that we care more on the AM1808, since that's the chip we supposed to use.

    You can feel confident that TI will deliver AM1808 devices that will work as described in our datasheet and perform as expected per our documentation.

    Because I do not know anything about the current situation with the HawkBoard, I cannot speculate on the source of the problems there.

    But we do offer other evaluation platforms that do demonstrate successful operation. Your concerns may be addressed more fully by acquiring one of those other boards while the HawkBoard situation is being resolved.

    I see, maybe it's the board defect, not the chip.

    Would you please recommend some of your other evaluation platforms, for AM1808? we hope it have open schematic and pcb files

    Thank you again, RandyP.

    Zhu,

    To your statement about board vs. chip defect, the possible set of problems with a system can be very large. I do not want to pretend to know that this HawkBoard issue is a board problem or a chip problem. What we can know from the current situation is that some of the HawkBoards do work and some have problems. We also know that other OMAP-L138 boards do work. So we can conclude that there are combinations of board design and chip features and production processes that lead to successful board operation.

    And I personally feel confident that the current HawkBoard situation will get resolved soon and that your confidence in both the AM1808/OMAP-L138 and the HawkBoard project will be fully restored.

    The Logic ZOOM Experimenter's Kit is an excellent platform for demonstrating and testing your software during development. You can register your board and have access to the design files, but I do not believe these are open to the community. They are well supported and an excellent source for you to build from within the scope of their license agreement.

    If open files are a requirement rather than just a desire, then you are still able to move forward with the HawkBoard information. Once the current issues are resolved, then you will know what changes, if any, need to be made.

    I doubt I have given you any new information here, but I hope it has been at least a little helpful.

    Regards,
    RandyP

    RandyP,

    Thanks for your detailed reply, it's certainly helpful and really appreciated.

    With such excellent emploee like you, I'm real confident that AM1808 is the right choice for us.
