Abstract

The embodiment of the invention provides a firmware upgrading method, electronic equipment, a storage medium and a signal latch circuit, and the firmware upgrading method comprises the steps: selecting one piece of firmware from firmware needing to be upgraded for upgrading, controlling the signal latch circuit in the firmware to latch the output level of the firmware after the firmware is upgraded, and, after the firmware is upgraded, controlling a signal latch circuit in the firmware to release the latch state of the output level; and after upgrading of the firmware is completed, upgrading firmware which is not upgraded continues to be selected from the firmware needing to be upgraded for upgrading till all the firmware needing to be upgraded. According to the embodiment of the invention, the output level is latched for the upgraded firmware, and the service function is continuously realized for other non-upgraded firmware, so that the problem of interruption of normally running services and even data loss caused by the fact that the firmware upgrade needs to be powered off to restart equipment is solved, the continuity of service proceeding is effectively guaranteed, and the convenience of firmware upgrade is improved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a firmware upgrading method, electronic equipment, storage media and a signal latch circuit. Background technique [0002] Application-specific integrated circuits (ApplicatI / On Specific Integrated Circuits, ASIC) are integrated circuits designed and manufactured according to specific user requirements and the needs of specific electronic systems. Currently, it is one of the most popular ways to design an ASIC using a complex programmable logic device (Complex Programmable Logic Device, CPLD) or a field programmable logic gate array (Field Programmable Gate Array, FPGA). Both CPLD and FPGA have user field programmable characteristics, and their firmware can be updated according to the needs of users to flexibly adjust the realized functions. [0003] In the prior art, the online upgrade of the firmware of the CPLD or FPGA mainly adopts a cold upgrade solution. The main step...
