Method for loading file by communication blank panel and transmitting loaded file by host machine end

Abstract

The invention relates to the technical field of communication and provides a method for loading a file by a communication blank panel and transmitting the loaded file by a host machine end. The method comprises the steps of: requesting a first stage loaded file to the host machine end after resetting; receiving the first stage loaded file returned by the host machine end according to a first stage loaded file request, wherein the first stage loaded file comprises a reset configuration word; and loading the first stage loaded file, and realizing that a hardware parameter is initiated according to the reset configuration word included in the first stage loaded file. Under the condition of no inclusion of an EEPROM (Electrically Erasable Programmable Read-Only Memory) on hardware, the invention realizes that the reset configuration word is initiated, thereby saving hardware resources.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a method for a communication single board to load a file with a communication single board and a host end to transmit and load files, and a host end. Background technique [0002] After the communication board is reset, the hardware parameters need to be initialized before starting the initialization program for other configurations. The hardware parameters that need to be configured for the communication board to work normally are usually called Reset Word. [0003] The existing communication single board realizes the reset configuration word initialization method as follows: [0004] Store the reset configuration word in a solid-state storage device such as EEPROM (Electrically Erasable Programmable Read-Only Memory), and map the solid-state storage device used to store the reset configuration word to the communication board after reset The first address area read. ...

AI Technical Summary

Problems solved by technology

[0029] 1) EEPROM will increase hardware cost;

[0030] 2) EEPROM needs to consider the problem of programming, which increases the difficulty of design;

[0031] 3) EEPROM loading will have loading reliability problems

[0032] But if the EEPROM is removed, it is impossible to initialize the reset configuration word normally to complete the initialization of the DDR SDRAM controller

The existing project file loading scheme must include EEPROM. If the EEPROM that stores the reset configuration word is deliberately added just for loading, it will cause a waste of hardware resources to a certain extent.
