MSP432E401Y: MSP432E401Y Custom Startup Function Does Not Appear to be Executed on Reset

Hello

I am trying to have a startup function execute prior to C initialization.

I have updated release.cfg as below

var Startup = xdc.useModule('xdc.runtime.Startup');
Startup.resetFxn = "&appResetFxn";
Startup.firstFxns[Startup.firstFxns.length++] = "&appStartupFxn_First";
Startup.lastFxns[Startup.lastFxns.length++] = "&appStartupFxnLast";

My startup file contains the following entry

void appResetFxn(void)
{

Yet this function never seems to execute at startup.

Perhaps there is something else I need to configure?

Please advise.

Thanks In Advance.
