[0054] In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings.

[0055] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0056] The following describes a memory chip-based power-on control method, device, equipment, and medium according to an embodiment of the present disclosure with reference to the accompanying drawings.

[0057] Before introducing the power-on control method based on a memory chip according to the embodiment of the present disclosure, the power-on control method based on a memory chip in the related art is first introduced.

[0058] like Figure 1 As shown, in the related art, the program of the general host central processing unit does not support the startup of other partitions, and there is no partition inside the storage chip for backing up the vehicle system startup data. Once a problem occurs with the vehicle system startup data in the startup partition, it can only be re-downloaded using the platform tool. There is no other remedy, and the reliability and user experience are poor.

[0059] To this end, the present disclosure proposes a new power-on control method based on a storage chip, which selects a logical partition according to the state of a power-on control pin, so that when the vehicle system fails to start up, it can be remedied through a spare partition, thereby improving the reliability of the vehicle system and user experience.

[0060] Figure 2 It is a flow chart of a power-on control method based on a memory chip according to an embodiment of the present disclosure.

[0061] It should be noted that the power-on control method based on the memory chip of the embodiment of the present disclosure is executed by the controller in the memory chip of the embodiment of the present disclosure, or by the software in the controller in the memory chip. The following description is made by taking the controller in the memory chip as an example.

[0062] It should also be noted that if Figure 3 As shown, the memory chip of the embodiment of the present disclosure includes a first logic partition and a second logic partition, the first logic partition stores normal vehicle system startup data, the second logic partition stores backup vehicle system startup data, and a startup control pin is set on the memory chip. Among them, the startup control pin can be selected from the pins with special functions in the memory chip, such as G5, E6, J10, and P10. Of course, a pin can also be added separately as the startup control pin. The specific setting method is not limited in the present disclosure.

[0063] like Figure 2 As shown, the power-on control method based on the storage chip of the embodiment of the present disclosure includes:

[0064] S1, get the status of the power-on control pin.

[0065] The state of the power-on control pin is related to a key or selection tool connected to the power-on control pin.

[0066] For example, when the power-on control pin is connected to a button, the controller identifies whether the button is pressed, wherein if the button is not pressed, the power-on control pin maintains a low-level signal; if the button is pressed, the power-on control pin generates a high-level signal.

[0067] S2, selecting a target partition from the first logical partition and the second logical partition according to the state of the power-on control pin.

[0068] As an implementable manner, when the power-on control pin is connected to the button, the target partition is selected from the first logic partition and the second logic partition according to the state of the power-on control pin, including: when the level signal on the power-on control pin is a first level signal such as a low level signal, the first logic partition is selected as the target partition; or when a second level signal such as a high level signal is generated on the power-on control pin, the second logic partition is selected as the target partition. That is, when the button is not pressed, the first logic partition is used as the target partition, and when the button is pressed, the second logic partition is used as the target partition.

[0069] It should be noted that the button in this embodiment is used as an emergency switch.

[0070] As another achievable manner, when the power-on control pin is connected to a selection tool such as a selector, a target partition is selected from the first logical partition and the second logical partition according to the state of the power-on control pin, including: when the power-on control pin receives a first selection signal sent by the selection tool, the first logical partition is used as the target partition; or when the power-on control pin receives a second selection signal sent by the selection tool, the second logical partition is used as the target partition. That is, a selection tool can be set on the power-on control pin, and the user can select the first logical partition or the second logical partition as the target partition through the selection tool.

[0071] S3, controlling the target partition to output corresponding vehicle system startup data so that the host central processor can start up.

[0072] When the controller determines that the target partition is the first logical partition, the controller outputs the normal vehicle system startup data stored in the first logical partition, so that the host central processing unit starts up according to the normal vehicle system startup data read; when the controller determines that the target partition is the second logical partition, the controller outputs the backup vehicle system startup data stored in the second logical partition, so that the host central processing unit starts up according to the backup vehicle system startup data read.

[0073] Therefore, the power-on control method based on the memory chip of the embodiment of the present disclosure sets a power-on control pin on the memory chip, so that the user can control the signal of the power-on control pin by pressing a button or selecting a tool, so that the memory chip selects a logical partition according to the signal of the power-on control pin, thereby achieving the dynamic selection of the first stage software. Figure 3From the entire process shown, it can be seen that the first logical partition can be used for normal vehicle system updates. Once the update fails or other reasons cause the data in the first logical partition to be damaged and the host CPU cannot be booted, the second logical partition can be selected by pressing buttons or selecting tools for rescue booting, thereby improving the reliability of the vehicle system and improving the user experience.

[0074] In one embodiment of the present disclosure, after the controller controls the target partition to output the corresponding vehicle system startup data so that the host central processor can be started up, it can also obtain the startup time of the host central processor, and determine whether the host central processor is successfully started up based on the time. Wherein, when the time is greater than the set time, it is determined that the host central processor fails to start up, and then a prompt message can be issued by sound and / or light to prompt the user to switch the logical partition; or, when the time is less than or equal to the set time, it is determined that the host central processor is successfully started up.

[0075] In summary, the storage chip disclosed in the present invention includes a first logical partition and a second logical partition, the first logical partition stores normal vehicle system startup data, the second logical partition stores backup vehicle system startup data, and a startup control pin is set on the storage chip. The startup control method based on the storage chip disclosed in the present invention first obtains the state of the startup control pin, and then selects the target partition from the first logical partition and the second logical partition according to the state of the startup control pin, and controls the target partition to output the corresponding vehicle system startup data, so that the host central processing unit can be started. Therefore, the method selects the logical partition according to the state of the startup control pin, so that after the vehicle system fails to start, it can be remedied through the backup partition, thereby improving the reliability of the vehicle system and the user experience.
