when ntfx_spis_init() is done , NRFX_ERROR_INVALID_STATE errer occured.
pcb_state is NRF_DRV_STATE_INITIALIZED.
my code is
int cc3235_spi_init(void)
{
nrfx_spis_config_t spis_config = NRFX_SPIS_DEFAULT_CONFIG(8,2,3,4) ;
dev_spis = device_get_binding(DT_LABEL(DT_NODELABEL(spi2))); // dev_spis is device , dev is composed by device and data
k_sem_init( &spis_sem, 1,1) ;
struct spi_nrfx_data *dev_data = get_dev_data(dev_spis);
nrfx_err_t result = nrfx_spis_init( &get_dev_config(dev_spis)->spis_inst,
&spis_config, event_handler, dev_data);
}
static void event_handler(const nrfx_spis_evt_t *p_event, void *p_context)
{
struct spi_context *ctx = p_context;
if (p_event->evt_type == NRFX_SPIS_XFER_DONE) {
//spi_context_complete(&dev_data->ctx, dev_data->dev, p_event->rx_amount); this function is need?
ctx->current_rx_cnt = ctx->current_rx_cnt + (p_event->rx_amount );
ctx->current_tx_cnt = ctx->current_tx_cnt + (p_event->tx_amount );
}
}
Please show me wrong point.
