Embodiment 1
[0021] refer to figure 1 , figure 1 It is a schematic diagram of a startup flow of a real-time operating system provided in Embodiment 1 of the present application. It should be noted that, in this application, a real-time operating system (English: Real Time Operating System, RTOS) may include a core program or an application program. The real-time operating system can control at least one real-time task operating system that runs in unison. The real-time operating system can be installed on various electronic devices, such as smart speakers, routers, etc. Of course, this is only an example and does not represent the application limited to this.
[0022] figure 1 In , the boot process of the real-time operating system includes the following steps:
[0023] Step 101, execute the code stored in the startup ROM inside the microcontroller unit, and perform the first step of initialization.
[0024] The initialization includes the initialization of RAM, and the micro control ...
Embodiment 2
[0033] In combination with the startup process described in Embodiment 1 of this application, Embodiment 2 of this application provides an emergency rescue method for a real-time operating system. Refer to figure 2 as shown, figure 2 It is a flow chart of a real-time operating system emergency rescue method provided in Embodiment 2 of the present application. The method can be applied to electronic devices installed with a real-time operating system. The method includes the following steps:
[0034] Step 201, start the core program of the real-time operating system.
[0035] In combination with the startup process described in Embodiment 1, before step 201, the code stored in the startup read-only memory inside the micro-control unit can also be executed to perform the first step of initialization, and then execute the bootloader to perform the second step of initialization, Of course, this is just an optional solution, which does not mean that the present application is li...
Embodiment 3
[0058] Based on the emergency rescue method of the real-time operating system described in Embodiment 2 above, Embodiment 3 of the present application provides a method for recording historical abnormal information, and describes the historical abnormal information described in Embodiment 2 in detail. Refer to image 3 as shown, image 3 A logical block diagram of a real-time operating system emergency rescue method provided in Embodiment 3 of the present application, the method can be applied to electronic devices installed with a real-time operating system, and the method includes the following steps:
[0059] Step 301. When the real-time operating system starts abnormally, update the historical record information.
[0060] Specifically, the information about the abnormal startup can be added to the historical record information, for example, the time of the abnormal startup can be added. It should be noted that the historical record information can be updated in real time,...
