LAUNCHXL-F280039C: External Reset No Longer Resetting Board

Part Number: LAUNCHXL-F280039C

Howdy,

I've been using the LaunchPad for a few months now. Today, the external reset button (XRSn) stopped functioning as it did before. Previously, pressing and releasing the button would reset the device. Now, when the button is pressed all GPIO pins are no longer driven, however upon releasing the button the program restores to the previous state as if the button was never pressed. I have three of the same boards in total and all of them are behaving this way after programming them. I do not believe that this was caused by damage to all three of the boards as one of the boards has never been attached to our booster design at all.

We are programming the boards using Simulink in MATLAB 2023b. Could this be due to a MATLAB setting?

Thanks in advance,

Cole
