How to start Zephyr bootloader (MCUBOOT) without XTAL 32768Hz?

[qwertynoon]

I have nrf52840 pcb without xTAL.

In this ticket ticket I have discused about start Zephyr project without XTAL onboard.

But now I faced with other issue to start mcuboot without XTAL

When XTAL is not installed on nrf52840 board - then after reset it does not run and wait for XTAL (as I understand)

If I include

CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y
CONFIG_CLOCK_CONTROL_NRF_K32SRC_XTAL=n

to bootloader\mcuboot\boot\zephyr\prf.conf

then I catch next error

I have made a big problem for me when I have not installed XTAL onboard, but it is too late. I have to start SMP server on notXTAL board.

Help me please

Hi,

 

This driver requires the use of multithreading, which enables certain kernel APIs. Could you try adding this to the mcuboot configuration?

CONFIG_MULTITHREADING=y

 

Kind regards,

Håkon

Thanks you a lot!!!!

You save me!!!

CONFIG_BOARD_ENABLE_DCDC=n
CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y
CONFIG_CLOCK_CONTROL_NRF_K32SRC_XTAL=n
CONFIG_MULTITHREADING=y

I included this in bootloader\mcuboot\boot\zephyr\prf.conf

and now it works!!!

There is one more issue. I use PPI for ADC and GPIO pending. When I connect and then disconnect - nrf52840 not advertise until reset the SoC.

        IRQ_CONNECT(DT_IRQN(DT_NODELABEL(adc)),
		    DT_IRQ(DT_NODELABEL(adc), priority),

        adc_configure();
        ppi_init();
        timer_init();

        IRQ_CONNECT(DT_IRQN(DT_NODELABEL(gpiote)),
		    DT_IRQ(DT_NODELABEL(gpiote), priority),
		    nrfx_isr, nrfx_gpiote_irq_handler, 0);
		    
        nrfx_gpiote_init(NRFX_GPIOTE_DEFAULT_CONFIG_IRQ_PRIORITY);

    nrfx_gpiote_in_config_t cfg_wdt = NRFX_GPIOTE_CONFIG_IN_SENSE_LOTOHI(false);
    cfg_wdt.pull = NRF_GPIO_PIN_PULLDOWN;
    nrfx_gpiote_in_init(TIM_WAKE, &cfg_wdt, evt_handler1);

    rtcConfig.pull  = NRF_GPIO_PIN_PULLUP;			

    nrfx_gpiote_in_init(RTC_PIN,     &rtcConfig,  evt_handler2);

    nrfx_gpiote_in_event_enable(RTC_PIN,     true);
    
    
    
    

P.S. Do I have to create a new ticket?
