Hi Adrian,

Yes, I do not see any issues with removing the if (!nrf_clock_lf_is_running()) check in timer_init.

I discussed the m_wdt_keep_internal_feed variable with the SDK developer and he confirmed that this was a bug. The m_wdt_keep_internal_feed flag can be removed entirely, i.e.
wdt_feed_timer_handler should look like this

static void wdt_feed_timer_handler(void)
{
        NRF_LOG_INFO("Feeding WDT.");
        wdt_feed();
}

Best regards

Bjørn
