compilation error due to enableWait in pwm

Kulwinder — Mon, 09 Jun 2025 15:25:53 GMT

for SDK_24_12_00_MIMXRT1064xxxxA under MIMXRT1064_features header file

/* @brief (e)FlexPWM has no WAITEN Bitfield In CTRL2 Register. */

#define FSL_FEATURE_PWM_HAS_NO_WAITEN (1)

then why .mex file adding ".enableWait" field in following structure in peripherial.c file while generating

pwm_config_t PWM1_SM0_config = {

.clockSource = kPWM_BusClock,

.prescale = kPWM_Prescale_Divide_128,

.pairOperation = kPWM_Independent,

.initializationControl = kPWM_Initialize_LocalSync,

.reloadLogic = kPWM_ReloadImmediate,

.reloadSelect = kPWM_LocalReload,

.reloadFrequency = kPWM_LoadEveryOportunity,

.forceTrigger = kPWM_Force_Local,

.enableDebugMode = false,

.enableWait = false

};

got compilation error as enableWait bit not defined as follow

typedef struct _pwm_config

{

bool enableDebugMode; /*!< true: PWM continues to run in debug mode;

false: PWM is paused in debug mode */

#if !defined(FSL_FEATURE_PWM_HAS_NO_WAITEN) || (!FSL_FEATURE_PWM_HAS_NO_WAITEN)

bool enableWait; /*!< true: PWM continues to run in WAIT mode;

false: PWM is paused in WAIT mode */

#endif /* FSL_FEATURE_PWM_HAS_NO_WAITEN */

pwm_init_source_t initializationControl; /*!< Option to initialize the counter */

pwm_clock_source_t clockSource; /*!< Clock source for the counter */

pwm_clock_prescale_t prescale; /*!< Pre-scaler to divide down the clock */

pwm_chnl_pair_operation_t pairOperation; /*!< Channel pair in indepedent or complementary mode */

pwm_register_reload_t reloadLogic; /*!< PWM Reload logic setup */

pwm_reload_source_select_t reloadSelect; /*!< Reload source select */

pwm_load_frequency_t reloadFrequency; /*!< Specifies when to reload, used when user's choice

is not immediate reload */

pwm_force_output_trigger_t forceTrigger; /*!< Specify which signal will trigger a FORCE_OUT */

} pwm_config_t;

Hello,

according to Reference Manual for MIMXRT1064 processors, the PWM CTRL2[WAITEN] bit is present. The compilation error you are observing is caused by bug in the MCUXpresso SDK which will be fixed in June's MCUXpresso SDK 25.06.00 release. As a temporary workaround you may change value of #define FSL_FEATURE_PWM_HAS_NO_WAITEN from (1) to (0).

Thank you for reporting this issue and apologies for the inconveniences!

Regards,

Lukas Heczko
