How to enable SPI2 in sdk14.2

[prateek]

Hi All,

i am stuck in SPI2 enable. i am using sdk 14.2 for our design in previous i am using sdk 12.0

i am simply follow these steps in 14.2 and 12.0 to enable spi2.

it will return error code 17(dec).

#define SPI2_INSTANCE 2

static const nrf_drv_spi_t spi_2; // = NRF_DRV_SPI_INSTANCE(SPI2_INSTANCE); // Error code 17

static const nrf_drv_spi_t spi_2 = NRF_DRV_SPI_INSTANCE(SPI2_INSTANCE); // error :: SPI2_IRQ not defined

void spi_2_event_handler(nrf_drv_spi_evt_t const * p_event,void * p_context)

{

    spi1TrCompleteFlag = true;

}

uint32_t spiMaster2Init(void)

{

// spi_2 init as master mode

    uint32_t ret = SPI_SUCCESS;

    nrf_drv_spi_config_t spi_2_config = NRF_DRV_SPI_DEFAULT_CONFIG;

    spi_2_config.ss_pin = SPI2_CS;

    spi_2_config.miso_pin = SPI2_MISO;

    spi_2_config.mosi_pin = SPI2_MOSI;

    spi_2_config.sck_pin = SPI2_CLK;

    spi_2_config.frequency = NRF_DRV_SPI_FREQ_4M;

    ret = nrf_drv_spi_init(&spi_2, &spi_2_config, NULL,NULL);

    return ret;

}

and in SDK_config.h

#ifndef SPI_ENABLED

#define SPI_ENABLED 1

#endif

#ifndef SPI2_ENABLED

#define SPI2_ENABLED 1

#endif

#ifndef SPI2_USE_EASY_DMA

#define SPI2_USE_EASY_DMA 1

#endif

please help me to resolved this error, in SDK 12.0 these steps is working but in 14.2 not working.

thank you.

Hi,

 

Could you check if sdk_config.h::PERIPHERAL_RESOURCE_SHARING_ENABLED is set to '1', and if it is, try setting it to zero?

Kind regards,

Håkon

Hi Hakon,

by default  PERIPHERAL_RESOURCE_SHARING_ENABLED is set to zero.

i also try with SPIx_INSTANCE 0 it gives unknown state error

when i try with SPIx_INSTANCE 2 it gives SPI2_IRQn is undefined in SDK 14.2 but in SDK12.0 no error comes.

Thanks & Regards,

Prateek

It sounds like there is something with the sdk_config.h file that has a mismatch between the two SDK versions. Could you try taking a new sdk_config.h file from SDK v14.2, then enabling the functionality you need to see if the issue disappears?

Kind regards,

Håkon
