ANT on PCA10056 and custom board ?

[RixtronixLAB]

Dear Members,

I want to run ANT+ code in my custom board,

It works well on PCA10056, I can upload softdevice and the code to custom board board,

but I didn't get any responses,

I have tried with code without softdevice, the custom board works well

Any ideas ?

Thanks

Hello,

Does your custom board have a 32KHz crystal mounted? If not, you have to make sure you select the internal RC oscillator when you enable the Softdevice. Otherwise, the Softdevice will enter an infinite loop waiting for the crystal to start.

The memory layout should be left as is.

Best regards,

Vidar

Does softdevice require VDD HV? I connected VDD HV to 3.3V .

without APP_ERROR_CHECK :

Which APP_ERROR_CHECK? The one after nrf_sdh_enable_request()? Also, os nrf_sdh_enable_request() called from ble_stack_init() as well, or only from softdevice_setup()?

How can I check my 32KHz crystal running ?

If you have selected the crystal, then it will be running once the nrf_sdh_enable_request() function has returned  with NRF_SUCCESS.

Hi Vidar, thanks for the reply

Yes, The one after nrf_sdh_enable_request(),

The running softdevice_setup is

/**@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");
}

Debug out :

fo> app: log_init.
nfo> app_timer: RTC: initialized.
fo> app: Rixtronix LAB. SP_BUTTON_ACTION_PUSH
fo> app: Rixtronix LAB. SP_BUTTON_ACTION_PUSH

fo> app: utils_setup
fo> app: softdevice_setup main
fo> nrf_sdh: nrf_sdh_enable_request
fo> nrf_sdh: CRITICAL_REGION_ENTER

Stop until this line :

 CRITICAL_REGION_ENTER();
         NRF_LOG_INFO("CRITICAL_REGION_ENTER\r\n");

is it possible that my XL1 and XL2 pad on 32KHz not soldered properly, causing this error ?

How can I use RC oscillator for running softdevice in debug mode ?

it ended up in this line :

How can I debug it (in which line) I put breakpoint ?

Await for your reply, thanks.

Debug and breakpoint screen shot :

Any clues ?

LFCLK Not Running

[Vidar Berg]

The program will not return from nrf_sdh_enable_request() unless the crystal oscillator has started, and you said earlier it did return. So it should not be an issue with the crystal not starting up. However, if you still suspect the 32KHz crystal to be the culprit, then you try to select the NRF_CLOCK_LF_SRC_SYNTH  source.

Can you print out the return value from nrf_sdh_enable_request()?

Can you print out the return value from nrf_sdh_enable_request()?

No I can not get the printout :

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

it stopped at

  CRITICAL_REGION_ENTER();
         NRF_LOG_INFO("CRITICAL_REGION_ENTER\r\n");

Have you seen my screen shot ?

LFCLKSTAT = 0

I have tried

 NRF_CLOCK_LF_SRC_SYNTH  source,

it's not responding as well...

What could have been wrong ?

Thanks
