Logging with timestamp on SDK 15.2

i have recently upgraded to SDK 15.2, and since doing so I am struggling to get timestamps working in the logger.

I am initialising the logger here:

    //Start microsecond timer:
    us_timer_config();
    ret_code_t err_code = NRF_LOG_INIT(time_us);
    APP_ERROR_CHECK(err_code);

And here is my microsecond timer. 

#include "velo_us_timer.h"
//
const nrf_drv_timer_t us_timer = NRF_DRV_TIMER_INSTANCE(1);


void us_timer_config(void)
{
	uint32_t err_code=NRF_SUCCESS;
		nrf_drv_timer_config_t timer_cfg = 
	{
		.frequency = NRF_TIMER_FREQ_1MHz,	//Sets prescaler to get a counter increment at 1MHz.
		.mode = NRF_TIMER_MODE_TIMER,		// in this mode counter increments by 1 on each clock cycle (clock x prescaler actually)
		.bit_width = NRF_TIMER_BIT_WIDTH_32,    
		.interrupt_priority = TIMER_DEFAULT_CONFIG_IRQ_PRIORITY, 
    .p_context          = NULL     
		
	};
		err_code=nrf_drv_timer_init(&us_timer,&timer_cfg,us_timer_event_handler);
		APP_ERROR_CHECK(err_code);
    nrf_drv_timer_enable(&us_timer);
}

// Timestamp function for logging
uint32_t time_us(void)
{
	uint32_t time = nrf_drv_timer_capture(&us_timer,NRF_TIMER_CC_CHANNEL0);
	return time;
}

When I log (using NRF_LOG_INFO("comment")) no timestamp appears.  This code worked in SDK 14.2 .  Any ideas what I'm misssing?  Thank you.

    Hi

    What example are you basing your project in? And how exactly did you upgrade the SDK? There might be some changes done to the logger in the sdk_config.h file if you just changed the SDK version of the example and added your custom code.

    Best regards,
