TIVA Development kit Weird behavior - Need Reset Procedure

Hi,


I am working on getting the speaker buzz and it does buzz occasionally.  I'm also working on couple of projects at the same time. Looks like MCU's memory gets confused about which program to run.

When I load speaker program it didnt work, after that I loaded the hello_widget program and  LCD froze, so I pressed the reset button on the kit and it started working. After that I again loaded my speaker program and it worked.

Any suggestions on resetting the complete board to factory settings?

    Hi Spandan, well you can use this, but I doubt that's your problem:

    www.ti.com/.../LMFLASHPROGRAMMER

    The problem could be that since you never did a power cycle or a system reset the registers didn't reset to the original state and instead they hold the previous value they add, even though you re-programmed the flash.
    If I am not mistaken the button is the same as a system reset or a core reset. Try at the beginning of the debug pressing the "system reset". It's the little IC icon, by default it does a core reset but if you press the arrow it will show you the "system reset" option.

    Hi,

    I did the external reset given on board. That reset switch will supposedly reset the micro. For now its working.
    Thanks for help.
