Is there a C671x DSP development kit with more than 16M Flash?

The standard kit C6713DSK has only 256K bytes of Flash, which is too small for my application. Is there a C671x DSP kit that has a large Flash?

    Hi Penghe,

    This is the only kit available from TI for C6713:

    If you are starting a new design, I would recommend using our newest devices: C6747 or C6748.

    Hi Mariana,

    Thanks for your recommendation. I am looking at L138/C6748 Development Kit (LCDK). It looks good. But it's a complex dual CPU board (One ARM, one DSP). Is there a simpler kit with just C6748?

    Thanks,

    Penghe

    Penghe,

    The LCDK is available using two different part numbers, so you can order the TMDXLCDK6748 if you only want the C6748 version.

    The L138 version can be used with only the DSP, if you want to use it that way, but the C6748 version is clearly going to operate the way you want.

    Hi RandyP,

    Thanks for your answer. I didn't realize there are two versions of dev kits. So what's the relationship between the L138 version and C6748 version?  If I develop C6748 software on L138 version, can it run on C6748 version as well?

    Thanks,
    Penghe

    Penghe,

    Yes, if you develop C6748 software on the L138 LCDK, you can run it on the C6748 LCDK as well.

    The L138 is the full device. We apply changes to the devices in production to remove the ARM core and label it C6748. We can save testing and can sell the device more cost-effectively this way.

    You can look at the bootloader documentation for the two devices to see if there are any differences in the way the devices boot. But once the DSP's software is loaded and it is running, that portion of both devices is the same.

    Hi RandyP,

    Your information is very helpful. My interest in the compatibility of the two boards is because we may purchase different kit versions. And we woule like to know whether the application developed on C6748 kit can run without modification on L138 version. (We don't mind if the L138 version is not compatible with C6748 version).

    We are in the process of deciding which board to buy. From the L138 wiki page, the LCDK price is $195, same as TMDXLCDK6748. But from http://www.ti.com/tool/tmdsevml138, the price is $1050. Do you think the wiki price is an error?

    (BTW, the wiki page looks having several other issues. Like the "Order now!" link is not working. And all LCDK purchasing links go to some MSP430 part.)

    Another question is about the availability, we are going to order TMDXLCDK6748 (or LCDK) from both US and Europe. Our initial research didn't find a suitable European distributors. Can you please point us to a distributor that provide the kit in Europe?

    Thanks a lot,
    Penghe

    Penghe,

    Sorry about the problems on the Wiki. I noticed that when I was looking for the LCDK info for you originally, but did not report it to anyone. I will report it now.

    You can definitely run a DSP application on both boards without modification. If you are running the application through CCS, then there may be a different startup script (GEL file) to run. If you want to boot from Flash, then the boot options will be important. But the DSP code will be completely compatible.

    You can click the link in my first post on this thread and it will take you directly to the C6748's LCDK. The TI eStore button seems to work correctly on that page. Next to the TI eStore button is a Buy from Distributor button.

    The EVM is $1050 because it has more features. You can compare the features to see if the extra cost is valuable to you.

    RandyP,

    Looking closer at the L138/C6748 dev kits, I am still a little confused. I found 4 different part numbers:

    1. TMDXLCDK6748. This is the one you mentioned earlier, with only C6748. The price is $195.
    2. TMDXLCDK138. This one looks like the full version of L138, but the price is also $195, same as in wiki.
    3. TMDSEVML138. This one is another full version of L138? The price is $1050.
    4. TMDSEXPL138. This one is also a full L138 board? The price is $495.

    Is the price of (2) also an error? What's the difference between 2, 3 and 4?

    Thanks a lot,
    Penghe

    Penghe,

    All of the prices are correct. At the four links in your post, each page describes the features of the respective boards. You can purchase whichever one you want. If the features in the lower cost boards are adequate for your needs, you will want to purchase those. If you want more features, you can purchase one of the other boards.

    Since you can read the different features on those pages, I will not copy them into this post. You may be confusing "full L138 device" with "full featured board". It is like buying a car - there are choices depending on the features you want, but they all have a 4-cylinder or 6-cylinder engine.

    Regards,
    RandyP
