HardFault_Handler by GPIOTE_IRQHandler

[qoboty]

When I use nrf_drv_gpiote driver by sdk8.1.0. with softDevice 8. I got HardFault_Handler when run in

handler(pin,polarity); in the GPIOTE_IRQHandler

How to deal with it?

below is the init code:

nrf_drv_gpiote_in_uninit(INFRAD_RECEIVE_PIN);
nrf_drv_gpiote_in_config_t receive_gpiote_config=GPIOTE_CONFIG_IN_SENSE_TOGGLE(true);
	
err_code=nrf_drv_gpiote_in_init(INFRAD_RECEIVE_PIN,&receive_gpiote_config,receive_gpiote_handler);
APP_ERROR_CHECK(err_code);

nrf_drv_gpiote_in_event_enable(INFRAD_RECEIVE_PIN,true);

below is the gpiote handler:

static void receive_gpiote_handler(nrf_drv_gpiote_pin_t pin, nrf_gpiote_polarity_t action){

 static uint32_t prev_cc1 = 0;
int64_t curr_wave;
uint32_t active_time;

	if(m_receive_halt>0)
		return;

  if( irparams.receive_begin==0)
	{
		irparams.receive_begin=1; 
		irparams.rawlen=0;
	}	

	if(irparams.rawlen>296)
		irparams.rawlen=0;
	
 if(irparams.receive_begin>0){
		 irparams.timer=0;
	 }
irparams.rawbuf[irparams.rawlen]=NRF_TIMER1->CC[g_channel_id];
	irparams.rawlen++;

	NRF_GPIOTE->EVENTS_IN[g_channel_id] = 0; 
	

}

Where in that code are you getting the hardfault?

What's irparams.rawbuf? You're assigning that from NRF_TIMER1->CC[...] which is a 32-bit value, if irparams.rawbuf[ irparams.rawlen ] isn't 4-byte aligned you'll hardfault.

I have find out the reason, when call pwm first, I got the error, when I do not use the pwm lib, it works well.

How many pwm channels did you make? nrf_drv_gpiote_in_init(...) will return error if all the GPIOTE channels are taken. Each PWM channel will allocate one GPIOTE channels.

Hi,i met the same problem in SDK13.1.My project has 2 HITOLO GPIOE events and 1 PWM.When the GPIOE event is occuring,the PWM is set and it led to the hardfault.However,when i close the PWM,it worked normally.How can i deal with it without closing the PWM.Thanks!
