Embodiment Construction

[0015] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0016] Referring to FIG. 2 , a method for controlling single board reset according to an embodiment of the present invention is illustrated. As shown in Figure 2, the single board reset control method includes the following steps: S202, providing the single board running state control signal to the programmable logic chip of the system where the single board is located; S204, controlling the state of the single board running state control signal, To control the signal output from the programmable logic chip to the watchdog chip of the system where the board is located, so as to control the reset of the board.

[0017] Wherein, the watchdog manual reset input end of the watchdog chip is connected to the programmable logic chip. In step S204, control the signal of the watchdog output terminal of the watchdog chip by controlling the...

Abstract

The present invention discloses a veneer-reset control method, and involves the following steps: S202, the control signal of the veneer running state can be supplied to a programmable logic chip of the system in the programmable logic chip the veneer is positioned; S204, the signal of the watchdog chip of the system in programmable logic chip the veneer is positioned, and thereby is output by the programmable logic chip, can be controlled by controlling the state of the control signal of the veneer running state, so as to control the veneer reset. The present invention can solve complex process that a veneer needs to be replaced when in debugging state, and the present invention can solve the defect that the codes of the testing veneer, and the finished veneer is different from the programmable logic code.

Description

technical field [0001] The invention relates to the application field of a central processing unit, and more particularly relates to a single board reset control method. Background technique [0002] The patent No. CN03131634 describes a device technology for controlling the selection of the watchdog function of the watchdog chip. Although this technology can keep the hardware of the debugging board and the finished board consistent, the disadvantage of this technology is that the debugging board and the hardware of the finished board can be consistent. The programmable logic code of the finished single board cannot be kept consistent. [0003] In the application field of single-board central processing unit (Center Processing Unit, referred to as CPU), the minimum CPU system generally consists of a boot (BOOT) chip, a flash memory (FLASH) chip, a random access memory (RAM) chip, a programmable logic chip, and Single board reset circuit configuration. Among them, the FLASH...
