However, in the cloud environment, serial communication between the IDE (Integrated Development Environment) container and the physical target board has become a problem. The traditional serial communication method is suitable for scenarios where the development environment host and the target board are directly connected via serial ports, but cannot be directly applied to the cloud environment, causing developers to encounter many inconveniences when using the cloud integrated development environment to develop embedded systems. Summary of the invention

[0003] In view of this, the present invention provides a method for serial port communication between an IDE container and a physical target machine, constructs a virtual serial port device, establishes a mapping relationship between the virtual serial port device and the physical target board, realizes virtual serial port sharing between the host machine and the IDE container based on container configuration, and the IDE container communicates with the physical target board through the virtual serial port device. The present invention can effectively solve the problem that the IDE container cannot directly access the serial port of the physical target board in a cloud environment, and improves the efficiency of embedded software development and the convenience of physical target board management.

[0004] The technical solution of the present invention:

[0006] The IDE container communicates with the physical target board based on a virtual serial port device.

[0007] Furthermore, the corresponding relationship is specifically as follows: multiple virtual serial port devices are established on the host machine, and each IDE container is connected to the target board through the virtual serial port device.

[0008] Furthermore, the corresponding relationship is maintained through a list or a file.

[0009] Furthermore, a plurality of ports are arranged on the server at the management side of the target board, and each port is connected to a target board.

[0010] Furthermore, the host creates a virtual device, requests the intranet IP of each port on the server, establishes a mapping relationship between the virtual device and the intranet IP of each port on the server, and stores and maintains the mapping relationship in the form of a local file.

[0011] Furthermore, when the host machine communicates with the target board via serial port, the serial port communication data is encapsulated into an IP data packet to implement serial port communication based on IP.

[0012] Furthermore, the host machine is a working node in the cloud environment, a virtual serial port driver is installed on the host machine, a virtual serial port device is created, the virtual serial port device is synchronized to the server, and the correspondence between the virtual serial port device and the server port is maintained through a local configuration file.

[0013] Furthermore, on the host machine, the virtual serial port device is mapped to the IDE container, so that the IDE can access the physical target board through the virtual serial port device.

[0014] Furthermore, the container is a docker container, and a group of qualified virtual serial port devices are mapped to the container using the --device-cgroup-rule='c 188:*rmw' startup parameter, so that the processes in the container are given read, write and mknod permissions.

[0015] Furthermore, a serial port communication protocol is implemented inside the IDE container, and a serial port terminal is added. The serial port terminal user configures serial port parameters, sends and echoes data; the user uses the serial port terminal to send data to the virtual serial port device, and the data is forwarded to the server through the virtual serial port driver, and then the data is forwarded to the serial port device of the physical target board by retrieving the correspondence between the virtual serial port device and the physical target board ID.

[0026] In one embodiment of the present invention, a method for serial communication between an IDE container and a physical target machine is provided, which is used to implement serial communication between the container and the target board in a cloud platform, and load or debug a program on the target board; Figure 1-Figure 2, the communication method includes: constructing a virtual serial port device on an IDE container host machine, and establishing a corresponding relationship between the virtual serial port device and the serial port device of a physical target machine; mapping the virtual serial port device of the host machine to the IDE container, so that the container can send and receive data to the virtual serial port device;

[0027] The IDE container communicates with the physical target board based on a virtual serial port device.

[0028] In this embodiment, the corresponding relationship is specifically: multiple virtual serial port devices are established on the host machine, and each IDE container is connected to the target board through the virtual serial port device.

[0029] In this embodiment, the corresponding relationship is maintained through a list or a file.

[0030] In this embodiment, a plurality of ports are arranged on the server at the management side of the target board, and each port is connected to a target board.

[0031] In this embodiment, the host creates a virtual device, requests the intranet IP of each port on the server, establishes a mapping relationship between the virtual device and the intranet IP of each port on the server, and stores and maintains the mapping relationship in the form of a local file.

[0032] In this embodiment, when the host machine performs serial communication with the target board, the serial communication data is encapsulated into an IP data packet to implement IP-based serial communication.

[0033] In this embodiment, the host machine is a working node in the cloud environment. A virtual serial port driver is installed on the host machine, a virtual serial port device is created, the virtual serial port device is synchronized to the server, and the correspondence between the virtual serial port device and the server port is maintained through a local configuration file.

[0034] In this embodiment, on the host machine, the virtual serial port device is mapped to the IDE container, so that the IDE can access the physical target board through the virtual serial port device.

[0035] In this embodiment, the container is a docker container, and the --device-cgroup-rule='c188:*rmw' startup parameter is used to map a group of qualified virtual serial port devices into the container, and grant the processes in the container read, write and mknod permissions.

[0036] In this embodiment, a serial port communication protocol is implemented inside the IDE container, and a serial port terminal is added. The serial port terminal user configures serial port parameters, sends and echoes data; the user uses the serial port terminal to send data to the virtual serial port device, and the data is forwarded to the server through the virtual serial port driver. Then, by retrieving the correspondence between the virtual serial port device and the physical target board ID, the data is forwarded to the serial port device of the physical target board.

[0037] In this embodiment, serial port server software is deployed on the physical target board side, and the serial port server software manages a group of physical target boards and binds a unique ID to the serial port device of each physical target board. Accessing a specific ID of the serial port server will be redirected to the serial port device of the specific physical target board.

[0038] Install the virtual serial port driver on the working node of the cloud environment, create a virtual serial port device, synchronize the virtual serial port device to the serial port server, and the server maintains the correspondence between the virtual serial port device and the physical target board ID.

[0039] Serial port servers and virtual serial port drivers can be implemented with the help of existing tools, such as NPort.

[0040] On the working node, map the virtual serial port device to the IDE container so that the IDE can access the physical target board through the virtual serial port device. For example, in a docker container, you can use the --device-cgroup-rule='c 188:*rmw' startup parameter to map a group of qualified devices to the container and grant the processes in the container read (r), write (w), and mknod (m) permissions.

[0041] Implement the serial communication protocol inside the IDE container and add a serial terminal to facilitate users to configure serial port parameters, send and echo data. Use the serial terminal to send data to the virtual serial port device, and the data is forwarded to the serial port server through the virtual serial port driver. Then, by retrieving the correspondence between the virtual serial port device and the physical target board ID, the data is forwarded to the serial port device of the physical target board.
