Thank you for the feedback, great to hear it is working!

Hey Helsing!
SPI Slave is working! Data is being transmitted and received!
Many thanks for the help!
Sincerely, Sergey.

Fabulous!
I am delighted!

I'll check the work tomorrow - but the project was assembled without errors!

Thank you!

Thank you for sharing the files.

It looks like you need to add the following line:

pinctrl-names = "default", "sleep";

to your overlay, like below.

 &spi3 {
    compatible = "nordic,nrf-spis";
    status = "okay";
    pinctrl-0 = <&spi3_default>;
    pinctrl-1 = <&spi3_sleep>;
    pinctrl-names = "default", "sleep";
    def-char = <0x00>;
};

Are you working on some sample? Would you be able to share your project?

RE: SPI Slave NRF5340 Init Error

I tried for SPI2 - same error when building,
I am aware of the impossibility of using SPI3/I2C3 at the same time.

RE: SPI Slave NRF5340 Init Error

helsing — Wed, 09 Nov 2022 14:07:48 GMT

Could you try building for spi2 instead?

From Peripherals with shared ID: "In general (with the exception of ID 0), peripherals sharing an ID and base address may not be used simultaneously. Only one peripheral can be enabled at a given ID."

SPIS is a shared resource so you can for example not use i2c3 and spi3 at the same time. The one you are not using needs to be disabled.

This is likely related to Pin Control. Did you migrate your project from an nRF Connect SDK version older than v2.0.0?

If you follow the link above you will find a an example showing the syntax for Pin Control that you may include in nrf5340dk_nrf5340.overlay:

&pinctrl {
    uart0_default: uart0_default {
        group1 {
            psels = <NRF_PSEL(UART_TX, 0, 5)>;
        };
        group2 {
            psels = <NRF_PSEL(UART_RX, 1, 1)>;
            bias-pull-up;
        };
    };
    uart0_sleep: uart0_sleep {
        group1 {
            psels = <NRF_PSEL(UART_TX, 0, 5)>,
                    <NRF_PSEL(UART_RX, 1, 1)>;
            low-power-enable;
        };
    };
};

Hi Sergii,

Could you please share your project's .overlay file?
