Warning (gpios_property) during build of SLM Shell sample

[ToruKatagiri]

Hello,

The following warning occures when I build the SLM Shell sample (Not changed original code).

<stdout>: Warning (gpios_property): /chosen:ncs,slm-gpio: property size (37) is invalid, expected multiple of 4

[Build Configuration]

• Target sample: SLM Shell (https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/cellular/slm_shell/README.html)
• Board: nrf5340dk_nrf5340_cpuapp
• toolchains: v2.6.0
• SDK: v2.6.0
• Using nRF Connect on VS Code

---

I think the following settings of devicetree (nrf5340dk_nrf5340_cpuapp.overlay) are causing this warning.
But, I don't know how to deal with it.

/ {

    chosen {
        ncs,slm-uart = &uart2;
        ncs,slm-gpio = &gpio0;
    };
};

Do you know what causes this warning?
Can I ignore this warning? Or do I need to do something about it?

Thank you.

Hi,

I have tested the same sample and have seen the same build warning 

<stdout>: Warning (gpios_property): /chosen:ncs,slm-gpio: property size (37) is invalid, expected multiple of 4

This warning is related to 2 dts files - nrf5340_cpuapp_peripherals.dtsi and nrf_5340_cpuapp.dtsi. The property value that devicetree gets is the path size of the /soc/peripheral@50000000/gpio@842500. It is safe to ignore this warning.

Best regards,
