Mowing robot firmware verification method

Abstract

The invention provides a mowing robot firmware verification method, and relates to the field of mowers. The firmware verification method for the mowing robot comprises the following steps: storing a verification function checkfunc in N byte storage spaces starting from a specified position Addr in firmware; copying N bytes starting from Addr in the firmware into a computer RAM (Random Access Memory) by utilizing an upper computer to run to obtain first verification data returned by a verification function checkfunc, and adding the first verification data to the tail of the firmware; and copying N bytes starting from Addr in firmware in a boot area of a machine to an MCU RAM (Random Access Memory) for running to obtain second verification data returned by a verification function checkfunc, comparing the second verification data with the first verification data, and when the first verification data and the second verification data meet a set rule, indicating that the verification is successful, otherwise, indicating that the verification fails. According to the verification method, the verification function does not need to be specified in advance in the boot, and compared with a verification function written in advance in the boot in a conventional method, the verification method provided by the embodiment has higher flexibility and can cope with the situation that the verification function is modified by firmware.

Description

Technical Field

[0001] The present invention relates to the field of lawn mowers, and more particularly, to a method for verifying the firmware of a lawn mowing robot. Background Art

[0002] With the continuous progress of computer technology and artificial intelligence technology, intelligent lawn mowers similar to intelligent robots have gradually entered people's lives. The intelligent lawn mower can automatically mow the grass and charge in the user's lawn without user intervention. When the machine leaves the factory, it generally needs to verify the firmware information. In the prior art, the firmware verification requires specifying a verification function in advance, with a single operation and no flexible adjustment. Summary of the Invention

[0003] The purpose of the present invention is to provide a method for verifying the firmware of a lawn mowing robot, which can improve the flexibility of verification and adapt to the situation where the verification function is modified in the firmware.

[0004] The embodiments of the present invention are implemented as follows:

[0005] In a first aspect, the present invention provides a method for verifying the firmware of a lawn mowing robot, including the following steps:

[0006] Step s100: Store the verification function check_func in the storage space of N bytes starting from the specified position Addr in the firmware;

[0007] Step s200: Use the host computer to copy the N bytes starting from Addr in the firmware to the computer RAM for running, obtain the first verification data returned by the verification function check_func, and add the first verification data to the end of the firmware;

[0008] Step s300: Copy the N bytes starting from Addr in the firmware to the MCU RAM in the boot area of the machine for running, obtain the second verification data returned by the verification function check_func, compare the second verification data with the first verification data, and when the first verification data and the second verification data meet the set rules, it indicates that the verification is successful, otherwise the verification fails.

[0009] In an optional embodiment, in step s100, the verification function check_func is stored in the storage space of N bytes starting from the specified position Addr in the firmware by specifying the icf file of the MCU.

[0010] In an optional embodiment, in step s300, the second verification data is compared with the first verification data, and when the first verification data and the second verification data are the same, it indicates that the verification is successful.

[0011] The beneficial effects of the embodiments of the present invention are as follows:

[0012] In summary, for the lawn mowing robot firmware verification method provided in this embodiment, first, a verification function check_func is stored in the storage space of N bytes starting from the specified position Addr in the firmware. Then, the host computer copies the N bytes starting from Addr in the firmware to the computer RAM for running, and the first verification data returned by the verification function check_func is obtained and added to the end of the firmware. Then, in the boot area of the machine, the N bytes starting from Addr in the firmware are copied to the MCU RAM for running, and the second verification data returned by the verification function check_func is obtained. The second verification data is compared with the first verification data. When the first verification data and the second verification data meet the set rules, it indicates that the verification is successful; otherwise, the verification fails. Such a verification method does not require a pre-specified verification function in the boot. Compared with the conventional method where the verification function is written in the boot in advance, the verification method provided in this embodiment has greater flexibility and can handle the situation where the verification function in the firmware is modified.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0017] It should be noted that like reference numerals and letters refer to like items in the following figures. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0018] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the present invention is usually placed during use.

When the first verification data and the second verification data meet the set rules, it indicates successful verification; otherwise, the verification fails.

[0027] Continuing from the above, the firmware verification method for the lawn mowing robot provided in this embodiment has at least the following advantages:

[0028] In the boot, there is no need to specify the verification function in advance. Compared with the verification function written in advance in the boot in the conventional method, the verification method provided in this embodiment has greater flexibility and can handle the situation where the firmware modifies the verification function.

[0029] In this embodiment, optionally, in step s100, the method of using the icf file of the specified MCU can be used to implement storing the verification function check_func in the N-byte storage space starting from the specified position Addr in the firmware. The specific scheme for implementing using the icf file of the specified MCU can refer to the existing well-known technologies. In this embodiment, to avoid repetitive narration, no detailed description is given.

[0030] In this embodiment, optionally, when comparing the second verification data with the first verification data in step s300, when the first verification data and the second verification data are the same, it indicates successful verification. That is to say, the set rule can be that the first verification data is the same as the second verification data.

[0031] The firmware verification method for the lawn mowing robot provided in this embodiment does not need to specify the verification function in advance in the boot. Compared with the verification function written in advance in the boot in the conventional method, the verification method provided in this embodiment has greater flexibility and can handle the situation where the firmware modifies the verification function.

[0032] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications.
