[quote user="ST-Kon"]I believe that LPUART on nrf52 should be robust enough to not depend on external device always behaving "correctly".[/quote]

I see, I have forwarded your suggested changes to the LPUART developer.

That's not an option as we already have units in the field.

Hi,

[quote user=""]It appears that when SLM boots up, it sends Ready but the bootloader never terminated its transmission of the boot banner (because it's not using LPUART).[/quote]

Could you try to configure the bootloader to use a different UART for the console/printing? Alternately, try to set CONFIG_BOOT_BANNER=n in the bootloader
