Network Core SPI Boot Error

[Xunard]

1、I used the spi_bitbang routine to port it to the network core to run, and after the program was burned, I used an oscilloscope to measure the CLK pin waveform and there was no change.

spibb0: spibb0 {

        compatible = "zephyr,spi-bitbang";

        status="okay";

        #address-cells = <1>;

        #size-cells = <0>;

        clk-gpios = <&gpio1 10 GPIO_ACTIVE_HIGH>;

        mosi-gpios = <&gpio1 1 GPIO_ACTIVE_HIGH>;

        miso-gpios = <&gpio1 2 0>;

        cs-gpios = <&gpio1 7 GPIO_ACTIVE_LOW>;

    };

2、Is there only one spi0 in the network core?

3、There are bluetooth, ipc, spi, burning program in the application core, Bluetooth can be turned on successfully, and I failed to turn on Bluetooth with the button reset. If I block SPI or IPC, reset Bluetooth with the button and it will start normally

Did you remember to allow the pins to be controlled by the network core?

Remember that you have to put those pins into "gpio_fwd" (nrf-gpio-forwarder) - otherwise they will be controlled by the application core exclusively.

[Xunard]

The network core does not control the GPIO those, only Bluetooth uart and ipc. If I apply the nuclear IPC routine to port the SPI, it will look like this.

       

If you can really run normally with just the IPC function, how to solve it

[Xunard]

NO，Is there a related routine? I don't know how to add it

[Sigurd Hellesvik]

Do you build for the nRF5340 DK or for a custom board?

[Xunard]

NRF5340 DK

[Sigurd Hellesvik]

Ah, never mind. I see now that led0 is in nrf5340dk_common.dtsi, so it is there for both cores.

Instead, you might be missing CONFIG_GPIO in your netcore configuration.

Which image do you run on the netcore?

When you know which, you can enable CONFIG_GPIO in project/sysbuild/<netcore_image>.conf. For example sysbuild/ipc_radio.conf if you run ipc_radio.

[Xunard]

I used peripheral_uart routine, and I added CONFIG_GPIO=y to prj.conf
