HELP ME! Oscillator fault flag never clears on msp430f47197

Hello,

The code host site you posted is blocked on my server so I cannot view your code in its entirety. Does the following code still cause the OFIFG?

#include <msp430.h>

int main(void)
{
  volatile unsigned int i;

  WDTCTL = WDTPW + WDTHOLD;                 // Stop WDT
  FLL_CTL0 |= DCOPLUS + XCAP11PF;           // DCO+ set, freq = xtal x D x N+1
  SCFI0 = FLLD_4+FN_4;                      // x4 DCO freq, 16MHz nominal DCO
  SCFQCTL = 121;                            // (121+1) x 32768 x 4 = 16 MHz
  FLL_CTL1 &= ~XT2OFF;                      // Turn on XT2

  // Loop until 32kHz crystal stabilizes
  do
  {
    IFG1 &= ~OFIFG;                         // Clear oscillator fault flag
    for (i = 50000; i; i--);                // Delay
  }
  while (IFG1 & OFIFG);                     // Test osc fault flag

  FLL_CTL1 = SELS | SELM_XT2;                 // Select SMCLK source as XT2CLK
  FLL_CTL2 |= XT2S_2;

  while(1);                                 // Loop in place
}

If so then your hardware might be at fault. Are you using a custom board or a TI EVM? Have you tried switching out external crystals?
