I can use 3 uart success

and then i add one i2c

when build them will happend

after i change to

build success~~~~

Its a kernel problem please solve this problem

[fatalfeel]

it check by ~/ncs/zephyr/soc/arm/nordic_nrf/validate_enabled_instances.c

#define CHECK(idx) \
    !(I2C_ENABLED(idx) && SPI_ENABLED(idx)) && \
    !(I2C_ENABLED(idx) && UART_ENABLED(idx)) && \
    !(SPI_ENABLED(idx) && UART_ENABLED(idx))

#define MSG(idx) \
    "Only one of the following peripherals can be enabled: " \
    "SPI"#idx", SPIM"#idx", SPIS"#idx", TWI"#idx", TWIM"#idx", TWIS"#idx \
    IF_ENABLED(CONFIG_SOC_SERIES_NRF53X, (", UARTE"#idx)) \
    IF_ENABLED(CONFIG_SOC_SERIES_NRF91X, (", UARTE"#idx)) \
    ". Check nodes with status \"okay\" in zephyr.dts."

#if !IS_ENABLED(CONFIG_SOC_NRF52810)
BUILD_ASSERT(CHECK(0), MSG(0));
#endif
BUILD_ASSERT(CHECK(1), MSG(1));
BUILD_ASSERT(CHECK(2), MSG(2));
BUILD_ASSERT(CHECK(3), MSG(3));

so  maybe i2c_2 need move to i2c_3

[Håkon Alseth]

Hi,

 

Some peripherals have a shared ID, as explained here:

https://infocenter.nordicsemi.com/topic/ps_nrf9160/peripheral_interface.html?cp=2_0_0_2_2_1#concept_shared_id

https://infocenter.nordicsemi.com/topic/ps_nrf9160/memory.html?cp=2_0_0_3_1_1#topic

 

This means that bus devices that share base address, like SPI*0, TWI*0, and UARTE0 on the nRF9160; only one of these can be enabled at the same time.

You cannot have i2c2 and uart2 enabled simultaneously for the nRF9160 device. As you mention, try moving one of these, like using i2c3 instead.

In case you have SPI enabled:

Note that you should disable spi3, as this is default enabled for the nrf9160dk_nrf9160 board:

&spi3 {
	status = "disabled";
};

 

Kind regards,

Håkoin
