I will try to emaulate this somehow, hoever as I said, It only happens just after the update. The time I run it, it just works.

It should be possible to set for instance a breakpoint in nrfx_timer_init() to find if it's failing in the following if statement or not:

    if (p_cb->state != NRFX_DRV_STATE_UNINITIALIZED)
    {
        err_code = NRFX_ERROR_INVALID_STATE;
        NRFX_LOG_WARNING("Function: %s, error code: %s.",
                         __func__,
                         NRFX_LOG_ERROR_STRING_GET(err_code));
        return err_code;
    }

Yes, I'm sure it's enabled. It won't compile otherwise, right?

Can't really check exactly where it fails. If i run the debug session, it's not the "first run after OTA update" and it just works :/

All I know is the debug information in the RTT console (error code and line# in main)

Are you sure you have set TIMER4_ENABLED 1 in sdk_config.h? If it's due to NRFX_DRV_STATE_UNINITIALIZED, then I get a feeling that

Are you able to find where exactly in nrf_drv_timer_init() the NRFX_ERROR_INVALID_STATE is returned?

UPDATE: The timers are defined as follows (both enabled in sdk_config:

const nrf_drv_timer_t TRIAC_TIMER = NRF_DRV_TIMER_INSTANCE(1);
const nrf_drv_timer_t LED_TIMER = NRF_DRV_TIMER_INSTANCE(3);

When I changed the LED_TIMER to 4 - it didn't help. Changing it to 2 - solved the problem. Still no clue why...
