libuarte and sdcard spi ?

Question

Dear Members,

I run 3 devices,

GPS on libuarte1

LCD on SPI2

Sdcard on SPI 1,

I'm using ANT and softdevice 340,

When I run LCD and SDcard outside the main loop, it's working ok,

by the time it's inside the main loop, it crashes with libuarte1,

Code :

									nrf_libuarte_async_config_t nrf_libuarte_async_config1 = {
            .tx_pin     = SER_APP_TX_PIN,
            .rx_pin     = SER_APP_RX_PIN,
            .baudrate   = NRF_UARTE_BAUDRATE_9600, //originally 28 Sept 2021
					  //.baudrate   = NRF_UARTE_BAUDRATE_38400,
            .parity     = NRF_UARTE_PARITY_EXCLUDED,
            .hwfc       = NRF_UARTE_HWFC_DISABLED,
            .timeout_us = 1000,
            .int_prio   = APP_IRQ_PRIORITY_LOW
			      
    };
		err_code=nrf_libuarte_async_init(&libuarte1, &nrf_libuarte_async_config1, uart_event_handler1, (void *)&libuarte1);
 /******************SDCARD  Sequence****************/   
 
			 
						NRF_SPI2->ENABLE = 0; //ILI9341 off
		          nrf_delay_ms(100);
			        NRF_SPI1->ENABLE = 1; //SDcard on
								
								fatfs_example();
								nrf_delay_ms(100);
								
		  /******************SDCARD  Sequence****************/   					  					
            printf("\rRixtronix LAB GPS Query.... \r\n");		
						 nrf_delay_ms(2000);
						GPSNeo_Process();
