GPIO/UART on EK-TM4C1294XL eval board

Other Parts Discussed in Thread: EK-TM4C1294XL, TM4C129XNCZAD, TM4C1294NCPDT

Trying to use the TI-RTOS examples to get started with EK-TM4C1294XL eval board.

USB examples work great except that User LEDs that are supposed to flash do not.

UART examples do not appear to do anything on the X1 header pins (I populated X1 with pins and am using a 5V level RS-232 to 12V RS-232 converter).

The examples indicate they are for the TM4C129XNCZAD processor, but the eval board has an TM4C1294NCPDT processor.

Is this the issue and I have to change some configuration to get it to work?  Where do I find docs on this?

Thanks

    Hello Greg,

    I am moving this post to TI-RTOS forum. Hopefully they can assist better.

    Thanks,

    Greg,

    What version of TI-RTOS are you using?

    And where are you seeing “The examples indicate they are for the TM4C129XNCZAD processor”?

    Thanks,
    Scott

    TI-RTOS version: 1.21.00.09

    In the partial screen shot below from CCS v5.1, the Resource Explorer shows examples for the TM4C129XNCZAD processor

    Greg,

    I don't see your screenshot.

    Is it possible for you to move to a later TI-RTOS release?  The one you are using is 2 years old now, and there have been many updates since that release.  I don’t know if it is the case, but it is possible that the issue you are seeing is resolved in the newer releases.  

    When I open Resource Explorer for the latest release (2.14.04.31) this board resides under the TM4C1294NCPDT device (below).

    Thanks,
    Scott

    When I viewed my reply that was supposed to contain the screen shot it didn't show up.  But now it does in your reply, so you can look at it there if it doesn't show up here.

    As far as upgrading, I am open to it.  We purchased a 5 user floating license several years ago for a different project that I did not work on (all those folks are gone now so I am a CCS newbie (with 30 years of embedded experience)).  On the TI price list for CCS, they don't show upgrade prices, where do I go to see that?

    Greg,

    If you have an existing CCS floating license you can use that with the latest version. You don't need to pay to upgrade. We used to require you to pay a yearly subscription fee to upgrade to major versions but discontinued that last year. It is just much better to have more people on the latest software.

    If you have that license setup on a license server you can just point CCS to that license server and it will use that to get a license. If you go to the help menu in CCS. Select "Code Composer Studio licensing information". Then click on the manage tab. There you can specify the address/name of the license server on your network.

    If you don't feel like messing around with setting up the connection to the license server right now that is fine. The reality is that if you are using the 129 eval board you can use a free CCS license with it. When you install CCS it will configure itself with a free license that will work with that eval board. When you start using your own board and an external debug probe you would then need to setup your CCS to use the license server. Or you could use one of the entry level XDS100 probes which would also work with the free license.

    Loaded latest version of compiler (Version: 6.1.2.00015) and it had support for my eval board that did not exist in v5.1.

    The user LEDs now blink.
