Problems solved by technology

This makes the staff need to switch back and forth between different serial ports when debugging or upgrading the firmware of the single board. The operation is very complicated, and the efficiency of debugging or upgrading is low.
In addition, during the whole machine test, when a problem occurs, the machine must be disassembled to access the serial port of the internal related chips. Dismantling the machine will not only easily destroy the test environment, but also increase the workload

Abstract

The application provides a serial-port switching device and storage equipment. The serial-port switching device provided by the application is applied to the storage equipment. The storage equipment includes a plurality of preset serial ports. The device is used to switch each preset serial port for connection with external debugging equipment or switch each of the other preset serial ports for connection with a serial port of a baseboard management controller (BMC) chip of a specified main-board, and includes a south-bridge PCH (Platform Controller Hub) chip and a complex programmable logic device (CPLD) chip. The PCH chip is connected with the CPLD chip. The CPLD chip is respectively connected with the above-mentioned plurality of preset serial ports and a serial port of the external debugging equipment. The PCH chip is used to generate control commands according to control-class information for the above-mentioned plurality of preset serial ports when the control-class information exists, and transmit the control commands to the CPLD chip. The CPLD chip is used to enable transmission channels, which are specified by the control commands, to be conductive according to the controlcommands. The serial-port switching device and the storage equipment provided by the application can improve debugging efficiency or upgrading efficiency.

Description

technical field [0001] The present application relates to the field of storage devices, in particular to a serial port switching device and a storage device. Background technique [0002] In the development and debugging stage of the storage device and the later firmware upgrade stage, it is usually necessary to connect some external serial ports. At present, the common method is to reserve some serial ports outside the chassis, and arrange serial ports of some chips on the board. This makes the staff need to switch back and forth between different serial ports when debugging or upgrading the firmware of the single board. The operation is very complicated, and the efficiency of debugging or upgrading is low. In addition, during the whole machine test, when a problem occurs, the machine must be disassembled to access the serial port of the internal related chips. Dismantling the machine will not only easily destroy the test environment, but also increase the workload. There...
