Here's the register, when I tried starting softdevice

I bought that crystal from aliexpress, the one from nRF, I can't find in stock, any suggestions for other crystal, mouser or digikey link ?

Thanks, so this confirms that the 32MHz crystal is not starting up.This means the Softdevice won't work either.

What crystal are you using in your design?

void clock_initialization()
{
    /* Start 16 MHz crystal oscillator */

    NRF_CLOCK->EVENTS_HFCLKSTARTED = 0;
    NRF_CLOCK->TASKS_HFCLKSTART    = 1;

   //CLOCK_HFCLKSTAT_SRC_Xtal

    /* Wait for the external oscillator to start up */
   /*
   while (NRF_CLOCK->EVENTS_HFCLKSTARTED == 0)
    {
         __WFE();
    }
*/
   nrf_delay_ms(500);
    /* Start low frequency crystal oscillator for app_timer(used by bsp)*/
    NRF_CLOCK->LFCLKSRC            = (CLOCK_LFCLKSRC_SRC_Xtal << CLOCK_LFCLKSRC_SRC_Pos);
    NRF_CLOCK->EVENTS_LFCLKSTARTED = 0;
    NRF_CLOCK->TASKS_LFCLKSTART    = 1;

/*
    while (NRF_CLOCK->EVENTS_LFCLKSTARTED == 0)
    {
       __WFE();
    }
   */
}

I can run that snippet,

but only RC clock are running

screen shot on register LFCLKSTAT and HFCLKSTAT

Will it work with softdevice ?

I'm not using softdevice now...

use this snippet then softdevice init ? is that possible ?

You can run the snippet you posted above at the start of main() to check if the HF and LF clock will start up.

Any clues ? thanks

Can I manually turn on external both clocks ?

Code :

void clock_initialization()
{
    /* Start 16 MHz crystal oscillator */
    NRF_CLOCK->EVENTS_HFCLKSTARTED = 0;
    NRF_CLOCK->TASKS_HFCLKSTART    = 1;

    /* Wait for the external oscillator to start up */
    while (NRF_CLOCK->EVENTS_HFCLKSTARTED == 0)
    {
        // Do nothing.
    }

    /* Start low frequency crystal oscillator for app_timer(used by bsp)*/
    NRF_CLOCK->LFCLKSRC            = (CLOCK_LFCLKSRC_SRC_Xtal << CLOCK_LFCLKSRC_SRC_Pos);
    NRF_CLOCK->EVENTS_LFCLKSTARTED = 0;
    NRF_CLOCK->TASKS_LFCLKSTART    = 1;

    while (NRF_CLOCK->EVENTS_LFCLKSTARTED == 0)
    {
        // Do nothing.
    }
}

ret_code_t err_code = nrf_sdh_enable_request();
APP_ERROR_CHECK(err_code);

Looks like the CPU is inside never ending loop, because it can not find 32KHz Crystal ?

Any clues ? Is it 32KHz crystal issue ?

Thanks

How can I use the Debug out from my nRF52840 DK ?

RE: ANT on PCA10056 and custom board ?

Vidar Berg — Tue, 19 Oct 2021 14:07:16 GMT

I don't know what the problem with your J-link could be. Did it suddenly stop working? And Is it a genuine J-link from Segger? Either way, you can use the Debug out from your nRF52840 DK instead.

Is it because of my J-Link ?

RE: ANT on PCA10056 and custom board ?

You need to pause the debugger by pressing the red stop button when the program hangs, then read the cpu registers.

Yes, it's valid, but it doesn't make sense that all registers are read as 0. When did you pause the debugger?

Can you read out the first word from address 0x0? It doesn't look like you have a valid Softdevice present.

OK, thanks. Please include the CPU register view as well so I can see where it hangs.

Did you place the breakpoint like I asked?

RE: ANT on PCA10056 and custom board ?

RixtronixLAB — Tue, 19 Oct 2021 13:10:22 GMT

same output :

I meant to delete the breakpoints, not remove the NRF_LOG_INFO () lines.

RE: ANT on PCA10056 and custom board ?

RixtronixLAB — Tue, 19 Oct 2021 13:05:14 GMT

delete all NRF_LOG_INFO and ,

ret_code_t err_code = nrf_sdh_enable_request();
APP_ERROR_CHECK(err_code); ,

complete function

/**@brief Function for ANT stack initialization.
*
* @details Initializes the SoftDevice and the ANT event interrupt.
*/
static void softdevice_setup(void)
{
      NRF_LOG_INFO("softdevice_setup main\r\n");
    ret_code_t err_code = nrf_sdh_enable_request();
      APP_ERROR_CHECK(err_code);
    ASSERT(nrf_sdh_is_enabled());

    err_code = nrf_sdh_ant_enable();
    APP_ERROR_CHECK(err_code);
      NRF_LOG_INFO("softdevice_setup sdh_enable\r\n");

    err_code = ant_plus_key_set(ANTPLUS_NETWORK_NUM);
    APP_ERROR_CHECK(err_code);
      NRF_LOG_INFO("ant_plus_key\r\n");
}

output :

and freeze, I can not see anything from

ret_code_t err_code = nrf_sdh_enable_request();
APP_ERROR_CHECK(err_code);

Any clues ?
