Hi,

I am using the evaluation board which has a reset button, I was wondering how to use the button to reset program to execute from the beginning. Is there a software configuration to enable the button

    Hello Kirushigan,

    The reset button S3 is connected to the MSP430FR5994 RST pin and requires no special configuration.

    When pressed, the device is forced into a reset state and when released the code will start from the beginning.

    Hi Dennis,

    my program has a packet being sent when it starts, I am reading that transmission pin on putty, it should re transmit the packet whenever I press the button however I am not seeing anything being transmitted, I also put a break point on the first line of my program and it never goes back to it.

    Update**

    Instead of debugging the program, I loaded the program and it worked, i'm curious to why it doesn't work when I use the debugger.

    Thanks,

    Kirushigan Parathan

    Using the Reset button causes the debugger to lose control of your system. Sometimes it recovers, but (my observation:) mostly it doesn't.

    To simulate the Reset button within the debugger -- as close as the debugger can get to that, anyway -- use the "Hard Reset" button up at the top.
