Hello!
I use a example for SDK in MCUXpresso but when debug the code, it is stoped.

Here the code from clock_config.c:

/*******************************************************************************
 * Variables for BOARD_BootClockRUN configuration
 ******************************************************************************/
const mcg_config_t mcgConfig_BOARD_BootClockRUN =
    {
        .mcgMode = kMCG_ModePEE,                  /* PEE - PLL Engaged External */
        .irclkEnableMode = kMCG_IrclkEnable,      /* MCGIRCLK enabled, MCGIRCLK disabled in STOP mode */
        .ircs = kMCG_IrcSlow,                     /* Slow internal reference clock selected */
        .fcrdiv = 0x0U,                           /* Fast IRC divider: divided by 1 */
        .frdiv = 0x0U,                            /* FLL reference clock divider: divided by 32 */
        .drs = kMCG_DrsLow,                       /* Low frequency range */
        .dmx32 = kMCG_Dmx32Default,               /* DCO has a default range of 25% */
        .pll0Config =

                .enableMode = MCG_PLL_DISABLE,    /* MCGPLLCLK disabled */
                .prdiv = 0x1U,                    /* PLL Reference divider: divided by 2 */
                .vdiv = 0x0U,                     /* VCO divider: multiplied by 24 */
            },
    };
const sim_clock_config_t simConfig_BOARD_BootClockRUN =
    {
        .pllFllSel = SIM_PLLFLLSEL_MCGPLLCLK_CLK, /* PLLFLL select: MCGPLLCLK clock */
        .er32kSrc = SIM_OSC32KSEL_LPO_CLK,        /* OSC32KSEL select: LPO clock */
        .clkdiv1 = 0x10010000U,                   /* SIM_CLKDIV1 - OUTDIV1: /2, OUTDIV4: /2 */
    };

    {
        .freq = 8000000U,                         /* Oscillator frequency: 8000000Hz */
        .capLoad = (OSC_CAP0P),                   /* Oscillator capacity load: 0pF */
        .workMode = kOSC_ModeOscLowPower,         /* Oscillator low power */

Hi Adrian Pellegrino,

If you are using FRDM-KL46Z board with latest MCUXPresso SDK_2.4.1_FRDM-KL46Z and MCUXpresso IDE.
Please check the Y1 crystal is well connected to Pin50 Pin51 of MCU or not.
I am able to run gpio example on FRDM-KL46Z(SCH-27822 REV C) board.

Best Regards,

Robin
