TIVA EXAMPLES NOT WORKING

Krishnan G Nair

Other Parts Discussed in Thread: LMFLASHPROGRAMMER, EK-TM4C1294XL

Hello,

I am new to ccs and tiva c.I am using ccs 5.4 and Ek -TMA4C1294xl evaluation kit.

I can debug the examples(blinky,hello,hibernate..........).After launching and connecting target and loading the (.out) file its automatically starts running.Its not stopping and no output is displayed.I changed the heap size.In code i edited for printf functions to display the output in screen.

I will be thankful if i got some clues to run the basic examples or to run some initial codes ,so that i can start developing from there.

Regards,

Krishnan

    Hi krishanan,

    You should use the latest version of CCS, v6?

    Why have you changed heap size? was this after or before trying to upload a example?

    Hello Krishnan,

    Has any example worked so far or is this the case from the first example you used? What if you flash the bin file in the blinky project via the LMFlashProgrammer. Does that work?

    Regards

    Hello,

    Mr. Luis Afonso

    Thank you  for the information.i will download and check ccs 6 soon.I got from forum only that heap size needed to be fixed to some values like(0x400.... other than 0,default case).I done that ony after importing example,before debugging the example.

    my requirement is i want to run some examples in TM4C1294(TM4C1294ncpdti)

    Board:EK-TM4C1294XL PCBA.

    Once the exampler is executed i can edit the code and view the output.From there i can tart the development.

    So ank kind information plese share.

    Regards,

    Krishnan

    Hello Krishnan,

    The examples are tested on the respective board and the bin file is provided as a backup to check if all is well for the example code that you want to use. The LMFlashProgrammer is a utility to get a bin file programmed to the device w/o need of IDE like CCS. This will tell the use if the board is well setup.

    I have used this approach and I know it works, so would suggest doing this step first.

    Regards

    Amit
