Embodiment 1

[0028] figure 1 It is a flow chart of a method for updating a device application program provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where the device application program needs to be restarted during the upgrade or downgrade process, for example, the vehicle radar device performs the application program In the case of an upgrade, the method can be performed by software or hardware, and specifically includes the following steps:

[0029] S110. The current program of the device sends a dog feeding signal to the watchdog module at a set time interval.

[0030] Among them, the current program is the running program in the device. For example, if the radar device is running an upgrade process, the current program is the application program in the radar device before the upgrade; when the radar device is being upgraded, the current The program is an upgrade program in the radar device; after the radar device is upgraded, the curr...

Embodiment 2

[0048] figure 2 It is a flow chart of a device application update method provided by Embodiment 2 of the present invention. This embodiment optimizes the situation that the device cannot be started due to unstable voltage on the basis of the above embodiments. This embodiment can Applicable to the situation where the device’s application program needs to be restarted during the update process, for example, when the vehicle-mounted radar device is upgrading the application program, the flash block storing the startup address is locked due to the voltage instability after power-on, this method can Executed by software or hardware, specifically including the following steps:

[0049] S210. The current program of the device sends a dog feeding signal to the watchdog module at a set time interval.

[0050] S220. If the running program of the device needs to be changed, the current program modifies the program start address in the boot area of ​​the storage device, and stops sendi...

Embodiment 3

[0061] image 3 It is a flowchart of a method for updating a device application program provided by Embodiment 3 of the present invention. This embodiment optimizes the situation that the device cannot be started due to the lack of a startup address on the basis of the above embodiments. This embodiment can Applicable to the situation where the device cannot be started due to the loss of the startup address during the update process of the device's application program, for example, the radar device cannot be started due to the loss of the startup address during the application upgrade of the vehicle radar device. This method can be implemented by software or hardware , including the following steps:

[0062] S310. The current program of the device sends a dog feeding signal to the watchdog module at a set time interval.

[0063] S320. If the running program of the device needs to be changed, the current program modifies the program start address in the boot area of ​​the stor...

Abstract

The embodiment of the invention discloses an equipment application program updating method and device, equipment and a storage medium. The method comprises: a current program of the equipment sendinga dog feeding signal to a watchdog module according to a set time interval; if the running program of the equipment needs to be changed, the current program modifying the program starting address in the starting area of the storage equipment and stopping sending the dog feeding signal to the watchdog module; if the watchdog module does not receive the dog feeding signal within the set time, sending a reset signal to a central processing unit of the equipment; and restarting the central processing unit according to the modified program starting address. According to the embodiment of the invention, the watchdog module acquires the accurate power-off time point according to the process of the upgrading program; and the equipment is automatically powered off and powered on, so that the situation that the power-off operation is carried out without modifying the starting address is avoided, and the problem that the equipment crashes due to the fact that the power-off operation is carried out without modifying the starting address during upgrading of the equipment is solved.

Description

technical field [0001] The embodiments of the present invention relate to computer equipment program processing technology, and in particular, to a method, device, equipment and storage medium for updating equipment application programs. Background technique [0002] The flash (non-volatile storage device) of the radar stores the application program and the upgrade program. The application program is used to collect and process radar data; the upgrade program is used to upgrade the application program. After running the upgrade program, the application program will be The program is upgraded to a higher version. Applications and upgrades are stored independently and run independently. The flash block of the radar also includes a boot area, which stores a boot address. When the launch address points to an application, the application is started. When the start address points to the upgrade program, the upgrade program will be started. [0003] Before and after the upgrade...
