Description

ARM singlechip burns record equipment

Technical Field

The utility model relates to ARM single-chip microcomputer burning equipment, and belongs to the technical field.

Background

At present, the ARM single chip microcomputer has three main burning modes: ICP (programming in circuit), IAP (programming in application), and ISP (programming in system). ICP needs to be supported by a hardware circuit, and a plate needs to be welded with an SWD/JTAG pin; the ISP uses a bootstrap program to burn through interfaces such as USB/UART and the like; the IAP realizes erasing and burning through software.

Some CPUs need to configure the CPU in an ISP mode, then burn BOOT programs in an ICP mode, and then burn application software and configuration data in combination with an IAP mode. Such a burning process has the following disadvantages:

1) the burning process is complex, and the USB/UART wire harness and the J-Flash wire harness need to be plugged and unplugged for many times in the process;

2) the CPU board must be welded with a debugging interface base, which is a challenge for some devices with limited space;

Detailed Description

The utility model is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention. Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

As shown in fig. 1, the ARM one-chip microcomputer burning device provided by the embodiment of the present invention includes:

the CPU to be burned comprises a UART interface and a power supply;

The CPU to be burned and the central control module are respectively provided with a first network port and a second network port, and the first network port is connected with the second network port through a network cable.

The GPIO module is connected with the LED, and the GPIO module is connected with the GPIO module.

And the CPU to be burned is also provided with a power-on reset module.

And the central control module is provided with a plurality of serial ports for connecting the CPU.

The specific burning process is as follows: initializing a CPU from a UART by using an ISP programming mode of an ARM singlechip CPU, automatically configuring the CPU after the initialization is finished, and then burning a BOOT program with a small volume into the CPU; after the completion, the CPU is reset again, and then the FTP service is built in the BOOT program, and the application program with larger volume and the corresponding configuration data are uploaded, so that the whole burning process of the CPU is completed.

Due to the fact that the transmission rate of the serial port is limited, only a BOOT program with a small size is burned into the CPU through the serial port in order to improve burning efficiency; while applications with larger volumes are transmitted over high transmission rate networks.

As shown in fig. 2, the specific process is as follows:

firstly, the central control computer judges whether a new CPU to be burned is inserted into the burning device or not through the state of a bayonet;

if a new CPU is inserted, the central control module configures the new CPU into an ISP starting mode through the GPIO, and then the new CPU is powered on through the power supply relay. If a serial port receives a correct reply, the serial port is considered to be connected with the new CPU, and then the serial port is communicated with the CPU through the serial port.

After the communication with the CPU is established, the existing configuration information of the CPU is read, and the read configuration information is analyzed and judged to judge whether the CPU needs to be reconfigured. If the configuration is needed, writing the preset configuration into the CPU through the ISP; otherwise, the configuration step is skipped. Different configuration data can be issued for different CPUs.

After configuration is completed, a BOOT program is burned into a CPU through a serial port, and a reset command is sent after burning is successful; and meanwhile, the starting mode of the CPU is set, the CPU is ensured to enter a normal program mode, and then the BOOT program which is just burned can be entered.

After the CPU is reset, the central control module judges whether the CPU successfully enters the BOOT program or not by continuously detecting the network message, and if the CPU is not on-line for a long time, an alarm is given to prompt abnormity.

After the CPU normally enters the BOOT, the application program and the configuration data with larger volume are uploaded to the CPU through an FTP command so as to complete the burning process. After the application program and the configuration data are uploaded, the central control module controls the power supply relay to power off the CPU, so that an operator can replace another CPU board conveniently.

And displaying different LED states in different burning stages to remind an operator.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
