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 invention relates to the technical field of communication, in particular to a method for loading files by a communication single board, a communication single board, and a host end for transmitting and loading files, and the host end. Background technique [0002] After the communication board is reset, the hardware parameters need to be initialized first, and then the initialization program can be started for other configurations. Generally, the hardware parameters that need to be configured to enable the communication board to work normally are called reset configuration words (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, Electrically Erasable Programmable Read-Only Memory), and map the solid-state storage device us...

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] However, if the EEPROM is removed, the reset configuration word cannot be initialized normally to complete the initialization of the DDRSDRAM 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.
