Hi, I have a spis problem#define SPIS_INSTANCE 1 /**< SPIS instance index. */ static const nrf_drv_spis_t spis = NRF_DRV_SPIS_INSTANCE(SPIS_INSTANCE);/**< SPIS instance. */ static volatile uint8_t m_spi_rx_buf[SPI_MAX_TX_SIZE]; /**< RX buffer. */ static volatile uint8_t m_spi_tx_buf[SPI_MAX_TX_SIZE]; /**< TX buffer. */ static void spis_event_handler(nrf_drv_spis_event_t event) { if (event.evt_type == NRF_DRV_SPIS_XFER_DONE) { spis_xfer_done = true; NRF_LOG_INFO(" SPI RX (%d).", event.rx_amount); } } uint32_t spi_init(void) { uint32_t err_code; nrf_drv_spis_config_t spis_config = NRF_DRV_SPIS_DEFAULT_CONFIG; spis_config.csn_pin = 22; spis_config.miso_pin = 24; spis_config.mosi_pin = 23; spis_config.sck_pin = 25; spis_config.mode = NRF_DRV_SPIS_MODE_3; spis_config.bit_order = NRF_DRV_SPIS_BIT_ORDER_LSB_FIRST; err_code = nrf_drv_spis_init(&spis, &spis_config, spis_event_handler); if (err_code != NRF_SUCCESS) { NRF_LOG_INFO("SPIS Init failure"); return err_code; } err_code = nrf_drv_spis_buffers_set(&spis, (uint8_t*)m_spi_tx_buf, sizeof(m_spi_tx_buf), (uint8_t*)m_spi_rx_buf, sizeof(m_spi_rx_buf)); if (err_code != NRF_SUCCESS) { NRF_LOG_INFO("SPIS buffer failure"); } return err_code; }
when nrf_drv_spis_buffers_set is called, it enters the switch on the SPIS_BUFFER_RESOURCE_CONFIGURED case, then calls spis_state_change with SPIS_BUFFER_RESOURCE_REQUESTED, spis_state_change then calls spis_state_entry_action_execute, at which point i get a fatal error
I cant seem to get any information here on what i have done wrong
the buffers arein data ram and pass the check
if i remove the buffers_set call the program runs, with it it hangs
any help here appreciated
thanks
billy
