Howdy,
I am using NRF5 SDK v15.0.0 on an nRF52810 custom PCB and am having a problem where the specified event handler is not being called upon completion of an SPIM transfer. Using a scope I can see that the transfer is occuring, but then the code gets caught at line 319 of arm_startup_nrf52810.s. I may be reading this incorrectly, but it looks like a default IRQ handler...
The relevant portion of my sdk_config.h file (all legacy driver definitions were removed):
// <e> NRFX_SPIM_ENABLED - nrfx_spim - SPIM peripheral driver //========================================================== #ifndef NRFX_SPIM_ENABLED #define NRFX_SPIM_ENABLED 1 #endif // <q> NRFX_SPIM0_ENABLED - Enable SPIM0 instance #ifndef NRFX_SPIM0_ENABLED #define NRFX_SPIM0_ENABLED 1 #endif
Relevant SPI initialization code and SPI EVT handler code:
#define SPI_INSTANCE 0
volatile uint8_t spiActive = SPI_MSG_IDLE;
volatile spi_pending_t spiPending;
volatile uint8_t spiTX[SPI_BUFFER_SIZE];
volatile uint8_t spiRX[SPI_BUFFER_SIZE];
static const nrfx_spim_t spiMaster = NRFX_SPIM_INSTANCE(SPI_INSTANCE);
static bool volatile spiXferComplete = false;
void spi_event_handler(nrfx_spim_evt_t const *event, void *context);
uint8_t _send_spi_message(uint8_t message);
void spi_init(void)
{
uint32_t error;
nrfx_spim_config_t config = NRFX_SPIM_DEFAULT_CONFIG;
config.sck_pin = SPI0_CONFIG_SCK_PIN;
config.miso_pin = SPI0_CONFIG_MISO_PIN;
config.mosi_pin = SPI0_CONFIG_MOSI_PIN;
error = nrfx_spim_init(&spiMaster, &config, spi_event_handler, NULL);
APP_ERROR_CHECK(error);
spiPending.all = 0x0000;
}
void spi_event_handler(nrfx_spim_evt_t const *event, void *context)
{
if(event->type == NRFX_SPIM_EVENT_DONE)
{
spiXferComplete = true;
TASK_SET_SPI_COMPLETE();
}
}
Location where it hangs (hangs at the "B ." at the end):

Everything compiles fine (no warnings), it just doesn't call the spi_event_handler() with the DONE event... Any help would be appreciated.
Thanks,
