spi master send data error at sd_nvic_DisableIRQ

Question

Hi all, 
 We have a issues with the SPI communication and hope someone could help us.
Using SDK 8.0.0 and Soft Device S110 8.0.0 
 code process step: 
 
 
 enable ble stack, and ble init. 
 
 
 spi_master_init(SPI_MASTER_0, spi_master_0_event_handler, false);
(spi init default: 1Mbps, MsbFirst, CPOL_ActiveHigh, CPHA_Leading, interrupt priority LOW)
by call api: spi_master_open() and spi_master_evt_handler_reg() 
 
 
 spi writer data using spi_master_send_recv() 
 
 
 spi writer data using spi_master_send_recv(), and error occur at
//Disable interrupt SPI.
APP_ERROR_CHECK(sd_nvic_DisableIRQ(p_spi_instance->irq_type)); // line: 431, error code: NRF_ERROR_SOC_NVIC_INTERRUPT_NOT_AVAILABLE 
 
 
 why the error occur on the second spi communication, and the system stops ?
Many thanks! terry.

Can you check if the irq_type value is `SPI0_TWI0_IRQn = 3, at the time of this call.
If it is so, then this is some softdevice bug in that version. I see that in latest SDK they have removed the sd_call and called direct NVIC_ functions. 
 Quick fix would be to replace all sd_nvic functions with NVIC_ functions directly. 
 APP_ERROR_CHECK(sd_nvic_ClearPendingIRQ(p_spi_instance->irq_type));
APP_ERROR_CHECK(sd_nvic_DisableIRQ(p_spi_instance->irq_type));
APP_ERROR_CHECK(sd_nvic_ClearPendingIRQ(p_spi_instance->irq_type));
APP_ERROR_CHECK(sd_nvic_SetPriority(p_spi_instance->irq_type, p_spi_master_config->SPI_PriorityIRQ));
 
 etc 
 to 
 NVIC_ClearPendingIRQ(p_spi_instance->irq_type);
NVIC_DisableIRQ(p_spi_instance->irq_type);
NVIC_ClearPendingIRQ(p_spi_instance->irq_type);
NVIC_SetPriority(p_spi_instance->irq_type, p_spi_master_config->SPI_PriorityIRQ);
 
 etc
