What are all the configuration options necessary to configure the nRF9160 as a SPI slave? I'm working with a custom board and have specific DTS files I'm working with. Here are all the config options in my board_defconfig file:
CONFIG_ARM=y
CONFIG_SOC_FAMILY_NRF=y
CONFIG_SOC_SERIES_NRF91X=y
CONFIG_SOC_NRF9160_SICA=y
# Enable MPU
CONFIG_ARM_MPU=y
# Enable TrustZone-M
CONFIG_ARM_TRUSTZONE_M=y
# This Board implies building Non-Secure firmware
CONFIG_TRUSTED_EXECUTION_NONSECURE=y
# enable GPIO
CONFIG_GPIO=y
# Enable uart driver
CONFIG_SERIAL=y
CONFIG_UART_0_NRF_UARTE=y
# Enable SPI driver
CONFIG_SPI=y
CONFIG_SPI_NRFX=y
CONFIG_SPI_SLAVE=y
CONFIG_SPI_3=y
CONFIG_SPI_3_NRF_SPIS=y
# enable console
CONFIG_CONSOLE=y
CONFIG_UART_CONSOLE=y
# additional board options
CONFIG_GPIO_AS_PINRESET=y
# entropy driver doesn't support nRF9160 yet
CONFIG_ENTROPY_NRF5_RNG=n
This results in the following build error:
C:/Users/me/Desktop/ncs/zephyr/ext/hal/nordic/nrfx/drivers/src/nrfx_spis.c:500:22: error: 'NRF_SPIS3' undeclared (first use in this function); did you mean 'NRF_SPIM3'?
spis_irq_handler(NRF_SPIS3, &m_cb[NRFX_SPIS3_INST_IDX]);
^~~~~~~~~
NRF_SPIM3
If the CONFIG_SPI _* lines are commented out the project builds and runs with UART working fine.
Is there something in the configuration that is being missed in order to enable the nRF9160 to operate as a SPI slave throught the SPIS3 peripheral?
