stuck at nrf_spim_task_trigger

[eleven-x_devteam]

Hi,

When I try spi commnucation with sensor on nrf52840 (using Mbed OS with SDK14.2), it stuck to nrf_spim_task_trigger(p_spim, NRF_SPIM_TASK_START); while spim_xfer is called.

I mean uart debug log stopped right before nrf_spim_task_trigger().

Any clue about this problem? or was there any similar issue to this?

Best regards,

Here is the code I am using.

#define SPI_INSTANCE 0 /**< SPI instance index. */

static const nrf_drv_spi_t spi = NRF_DRV_SPI_INSTANCE(SPI_INSTANCE); /**< SPI instance. */

    nrf_drv_spi_config_t spi_config = NRF_DRV_SPI_DEFAULT_CONFIG;

    spi_config.frequency = SENSOR_DEFAULT_SPI_FREQUENCY;

    spi_config.ss_pin = A111_SPI_CS_N_Pin;

    spi_config.miso_pin = A111_SPI_MISO_Pin;

    spi_config.mosi_pin = A111_SPI_MOSI_Pin;

    spi_config.sck_pin = A111_SPI_CLK_Pin;

    APP_ERROR_CHECK(nrf_drv_spi_init(&spi, &spi_config, spim_event_handler, NULL));

    nrf_gpio_cfg(spi_config.sck_pin,

     NRF_GPIO_PIN_DIR_OUTPUT,

     NRF_GPIO_PIN_INPUT_CONNECT,

     NRF_GPIO_PIN_NOPULL,

     NRF_GPIO_PIN_H0H1,

     NRF_GPIO_PIN_NOSENSE);

   nrf_drv_spi_transfer(&spi, tx_buffer, buffer_size, buffer, buffer_size);
