MSP430FR5994: Design Help

Hello E2E Experts,

Good day.

I am trying to get the HFXT to work on the MSP430FR5994 launchpad board.

 This is very urgent and for an important demo where I need higher accuracy than the low-power clock sources can provide!

 The crystal oscillator that I am trying to use is:

ECS-120-S-4

 The capacitor values that I am trying to use are:

C8 = 15pF

And

C9 = 3.3pF

 Also, trying to use

C8 = 3.3pF

And

C9 = 15pF

 The code that I am using is as follows:

       // Using HFXT

    CS_setExternalClockSource(32768, 12000000);

    CS_turnOnHFXT(CS_HFXT_DRIVE_16MHZ_24MHZ);

    //CS_turnOnHFXTWithTimeout(CS_HFXT_DRIVE_8MHZ_16MHZ,0x100);

    CS_initClockSignal(CS_MCLK, CS_DCOCLK_SELECT,  CS_CLOCK_DIVIDER_1);

    CS_initClockSignal(CS_ACLK, CS_LFXTCLK_SELECT, CS_CLOCK_DIVIDER_1);

    CS_initClockSignal(CS_SMCLK,CS_HFXTCLK_SELECT,  CS_CLOCK_DIVIDER_1);

However, the code keeps stopping in CS_turnOnHFXT()

 In the while loop, because of what I suppose is an oscillator fault (and it can’t get out because of the flag being set):

    while(HWREG8(CS_BASE + OFS_CSCTL5) & HFXTOFFG)

    {

        //Clear OSC flaut Flags

        HWREG8(CS_BASE + OFS_CSCTL5) &= ~(HFXTOFFG);

        //Clear OFIFG fault flag

        HWREG8(SFR_BASE + OFS_SFRIFG1) &= ~OFIFG;

    }

My question is:

1. What is causing this?
2. What can we do to stop it from happening and get the clock source operational?

Is there something wrong with trying to use this Q2 on the launchpad?

Is there something wrong with our hardware choices (please see above)?

Is there something wrong with the software we are using?

Any help you can provide would be much appreciated.

Regards,

CSC
