SPI worked strangely(external SPI Fash)

Question

Hi, I am using custom board with nRF52832.In the custom board, there is a SPI flash to storage some data. I can read or write the flash normally at the beginning,but whenI create a timer to read/write the flash, the SPI interface will never work normally again. The spi_xfer_done will never turn to true. Before into for(;;), I can read/wirite the data normally in W25QXX_Init() or W25QXX_test().But when I create a 1s timer to read/write again(W25QXX_test()), the RTT Viewer will always print "SPI WRITE". BTW, my application is based on examples\ble_peripheral\ble_app_uart\pca10040\s112 and I have closed the bspxx to avoid the conflict of GPIO. To find the reason of SPI error, I added LOG in SPI driver when create the timer. Here is the application code. int main(void) { // bool erase_bonds; // ret_code_t err_code; // Initialize. log_init(); // Initialize the async SVCI interface to bootloader before any interrupts are enabled. // err_code = ble_dfu_buttonless_async_svci_init(); // APP_ERROR_CHECK(err_code); timers_init(); // buttons_leds_init(&erase_bonds); power_management_init(); ble_stack_init(); // sd_power_dcdc_mode_set(NRF_POWER_DCDC_DISABLE); gap_params_init(); gatt_init(); services_init(); advertising_init(); conn_params_init(); m_application_config(); m_timer_init(); // m_work_upgrade_event(); // Start execution. NRF_LOG_INFO("Debug logging for UART over RTT started."); advertising_start(); W25QXX_test(); // Enter main loop. for (;;) { // m_work_nus_event(); idle_state_handle(); } } /**@brief Function for configurate IO. * * @details */ void m_application_config(void) { nrf_gpio_cfg_output(M_OUT_OE_PIN); nrf_gpio_pin_set(M_OUT_OE_PIN); nrf_gpio_cfg_output(M_OUT_RESET_PIN); nrf_gpio_pin_set(M_OUT_RESET_PIN); nrf_gpio_cfg_output(M_OUT_BOOT_PIN); nrf_gpio_pin_clear(M_OUT_BOOT_PIN); W25QXX_Init(); } void W25QXX_Init(void) { uint8_t flash_w_data[9]="12345678"; uint8_t flash_r_data[8]={0}; m_spi_init(); //³õÊ¼»¯SPI W25QXX_PowerDown(); W25QXX_WAKEUP(); W25QXX_TYPE=W25QXX_ReadID(); //¶ÁÈ¡FLASH ID.
