Summary:The invention provides a BMC FLASH redundant backup recovery system and method, and belongs to the technical field of BMC firmware upgrade.The system comprises an MCU, a level shifter, a main FLASH chip, a redundant FLASH chip and a connector terminal; the MCU is respectively connected with the main FLASH chip and the redundant FLASH chip through SPI (Serial Peripheral Interface) buses; the MCU is connected with the connector terminal through an upgrade signal line UPDATE and a recovery signal line RECOVERY; the MCU is connected with the level shifter through a control signal line CTRL; and the level translator is connected with the connector terminal and the main FLASH chip through an SPI (Serial Peripheral Interface) bus. According to the method, the BMC mirror images in the FLASH chips can be recovered only through the two FLASH chips, so that the cost is reduced, and the manpower is saved. 本发明提供一种BMC FLASH冗余备份恢复系统及方法，属于BMC固件升级技术领域，所述系统包括MCU、电平转换器、主FLASH芯片、冗余FLASH芯片以及连接器端子；MCU与主FLASH芯片和冗余FLASH芯片分别通过SPI总线连接
