External SPI flash XFLASH is not responding错误分析
打印机可能会开机时候在LCD显示屏上显示External SPI flash XFLASH is not responding错误。 该错误一个最直观的影响就是Blet test操作是无法显示数值的,一直显示0. 源码文件Marlin_main.cpp 1052行 1093行 1331行均是相关代码
static void xflash_err_msg() { lcd_clear(); lcd_puts_P(_n("External SPI flash\nXFLASH is not res-\nponding. Language\nswitch unavailable.")); } // "Setup" function is called by the Arduino framework on startup. // Before startup, the Timers-functions (PWM)/Analog RW and HardwareSerial provided by the Arduino-code // are initialized by the main() routine provided by the Arduino framework. void setup() { timer2_init(); // enables functional millis mmu_init(); ultralcd_init(); spi_init(); lcd_splash(); Sound_Init(); // also guarantee "SET_OUTPUT(BEEPER)" selectedSerialPort = eeprom_read_byte((uint8_t *)EEPROM_SECOND_SERIAL_ACTIVE); if (selectedSerialPort == 0xFF) selectedSerialPort = 0; eeprom_update_byte((uint8_t *)EEPROM_SECOND_SERIAL_ACTIVE, selectedSerialPort); MYSERIAL.begin(BAUDRATE); fdev_setup_stream(uartout, uart_putchar, NULL, _FDEV_SETUP_WRITE); //setup uart out stream stdout = uartout; #ifdef XFLASH bool xflash_success = xflash_init(); uint8_t optiboot_status = 1; if (xflash_success) { optiboot_status = optiboot_xflash_enter(); #if (LANG_MODE != 0) //secondary language support update_sec_lang_from_external_flash(); #endif //(LANG_MODE != 0) } else { xflash_err_msg(); } #else const bool xflash_success = true; #endif //XFLASH
通过查看源码,发现该错误信息是Arduino的Setup函数初始化中显示的。
