Firmware data processing method and device, equipment and storage medium

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...

Problems solved by technology

[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 programmed once, which makes the production cost higher, the efficiency of firmware data programming is low, the production process is complicated, and it is easy to cause programming errors in the production process

[0004] In addition, when the board needs to be upgraded during the use of the board, only part of the firmware data, such as the firmware data of the programmable logic device, can be upgraded. Other firmware data has been fixed during production and cannot be modified online. If there is a problem with the firmware data, It needs to be returned to the factory for maintenance to modify, the operation is cumbersome, and the processing cycle is long, which affects the use
