SoftDevice with Timer peripherals goes to app_error_weak.c

[Raja Sumant]

I am trying to measure frequency of a gpio pin.

I am using the code from the below thread -

https://devzone.nordicsemi.com/f/nordic-q-a/9036/measuring-input-gpio-pin-frequency-with-soft-device-running

I did modify it to be suitable with the new SDK V17.

//The  mode 1 was depcrecated so I am using the below modes.
NRF_TIMER1->MODE = 0; // Timer mode

NRF_TIMER2->MODE = 2; // Low power counter mode

I have added the custom ble service / characteristic tutorial code along with this.

When I run the code on debug mode, it goes to app_error_weak.c

I am not sure why this is happening. I tried to create break points but I am unsure from where this is being triggered.

However, the BLE service runs fine. It does not stop or create issues.

I am a bit new to SoftDevice. May I know where am I going wrong?

Hi

Please make sure you've set NRF_LOG_BACKEND_UART_ENABLED to 0 in sdk_config.h. If you still don't see any information in the debug terminal, please try changing the 

NRF_FPRINTF_FLAG_AUTOMATIC_CR_ON_LF_ENABLED define in sdk_config.h as well.

Best regards,

Simon

NRF_LOG_BACKEND_UART_ENABLED set to 0 already. 

NRF_FPRINTF_FLAG_AUTOMATIC_CR_ON_LF_ENABLED is  also set to 1

I am seeing nothing.

If NRF_FPRINTF_FLAG_AUTOMATIC_CR_ON_LF_ENABLED is already set to 1, try setting it to 0 instead. You can also make sure that DEBUG is set in your preprocessor definitions.

Best regards,

Simon

Hi. I got it enabled. It shows this:



May I know why this is being caused?

Hello Simon,

I got the following:



It reaches here. (void) sd_nvic_critical_region_exit(nested);

Could you please let me know what does this mean and how can I get rid of this error?

__STATIC_INLINE uint32_t sd_nvic_critical_region_exit(uint8_t is_nested_critical_region)
{
  if (nrf_nvic_state.__cr_flag && (is_nested_critical_region == 0))
  {
    int was_masked = __sd_nvic_irq_disable();
    NVIC->ISER[0] = nrf_nvic_state.__irq_masks[0];
    NVIC->ISER[1] = nrf_nvic_state.__irq_masks[1];
    nrf_nvic_state.__cr_flag = 0;
    if (!was_masked)
    {
      __sd_nvic_irq_enable();
    }
  }

  return NRF_SUCCESS;
}
