Program downloading system and method of PCIE/PCIX external plug-in card

Abstract

The invention discloses a program downloading system and method of a PCIE / PCIX external plug-in card, and belongs to the technical field of a server board card. The system comprises a PCIE / PCIX external plug-in card, a test conversion tool, a program downloading host and a program downloading device, wherein the main controller and a digital power supply device are arranged on the PCIE / PCIX external plug-in card, different kinds of PCIE / PCIX interfaces are correspondingly arranged on the test conversion tool according to differences of the PCIE / PCIX external plug-in card, and in addition, a switch controller is installed; the program downloader is connected with the program downloading host and the test conversion tool; the program downloading host installs the program downloading software; an SMBus switching interface of the switching controller is connected with an SMBus interface formed in a digital power supply chip of the digital power supply device, and the switching controller is in charge of switching the program loading of the PCIE / PCIX external plug-in card. The system and the method have the advantages that the program downloading speed is accelerated, the on-line test process is accelerated, and the production efficiency is improved.

Description

technical field [0001] The invention discloses a program downloading system and method, which belong to the technical field of server boards, in particular to a program downloading system and method for a PCIE / PCIX external card. Background technique [0002] In current server products, high-performance PCIE / PCIX add-in cards are often used to realize function expansion and performance improvement of the whole machine. Such as: SAS12G memory card, GPU graphics card, 10G / 40G network card, 16G fiber optic HBA card, etc. Using these add-in cards to achieve high-speed, high-performance design specifications requires that the power supply settings of the board cards must have the characteristics of high efficiency, high reliability, and intelligent monitoring. At present, digital power devices are mainly used to cooperate with external card board power supply settings. Digital power supply device is a combination of traditional power supply and microcontroller, using digital pr...
