Embodiment Construction

[0051] The core of the present application is to provide a firmware data processing method, which can be applied to a programmable logic device, such as a programmable logic device in a board of a rack switch. Multiple boards of different types can be deployed in the switch, and each board has multiple firmware data that need to be programmed or upgraded online. The programmable logic device is connected to the firmware data memory through the channel selector. The firmware data memory is used to store the firmware data of the programmable logic device and the firmware data of each chip connected to the programmable logic device. The firmware data memory can be specifically a FLASH chip. The firmware data in the board is stored in the firmware data memory, and at the same time, the firmware data can be backed up.

[0052] A programmable logic device (Programmable Logic Device, PLD) is produced as a general-purpose integrated circuit, and its logic function is determined accord...

Abstract

The invention discloses a firmware data processing method which is applied to a programmable logic device, the programmable logic device is connected with a firmware data memory through a channel selector, and the firmware data memory is used for storing firmware data of the programmable logic device and all chips connected with the programmable logic device. The method comprises the steps of reading and loading firmware data of the programmable logic device in the firmware data memory after power-on starting, opening of a first channel of a channel selector and closing of a second channel; and after the firmware data of the programmable logic device is loaded, controlling the first channel to be closed and the second channel to be opened, and reading and loading the firmware data of each chip connected with the programmable logic device in the firmware data memory. By applying the technical scheme provided by the invention, the firmware data in a board card can be quickly programmed or upgraded, and the firmware data processing efficiency is improved. The invention furthermore discloses a firmware data processing apparatus and device, and a storage medium, which have corresponding technical effects.

Description

technical field [0001] The present application relates to the technical field of computer applications, and in particular to a firmware data processing method, device, device and storage medium. Background technique [0002] In the board, programmable logic devices are usually deployed, and multiple chips with different functions are also deployed, such as EEPROM (Electrically Erasable Programmable read only memory, electrically erasable programmable read-only memory) chips, FLASH (flash memory) chips, etc. , PLDs and different chips correspond to different firmware data. [0003] At present, in the production of boards, it is necessary to perform firmware data programming operations on programmable logic devices and each chip. Different types of firmware data need to be programmed with corresponding types of downloaders. How many types of firmware data are there on the board? How many downloaders are needed for firmware data, and each type of firmware data needs to be prog...
