Thanks, We're on version 3.2.99 and sdk 2.3.0 which didn't have the pm-device-runtime-auto option yet. I updated to the latest version of zephyr to try it out and even without those changes it worked. With the change it also worked. We'll use the latest zephyr release going forward.

Hello Francisco,

Could you try adding the following snippet to your device tree?

/ {
    rtt0: rtt_chan0 {
        compatible = "segger,rtt-uart";
        zephyr,pm-device-runtime-auto;
    };

    chosen {
        zephyr,console = &rtt0;
    };
};

Thanks,

Helmut Lord

We're running zephyr 3.2.99 and sdk 2.3.0.

Its a custom board using a nrf52840.

Previously we were using zephyr 2.4.0 and sdk 1.4.1 and although CONFIG_PM_DEVICE_RUNTIME didn't exist at that time, we were able to use RTT Logging and CONFIG_SYS_POWER_MANAGEMENT at the same time.

Hello Francisco,

What SDK version are you using? Which application you are running on your board? Is this nordic DK or custom board?

Thanks.

Kazi

As a side note, if we route the logging over UART it does work, however we'd like to also have the ability to log over RTT.
