Detailed Description
As described above, fig. 1 is a schematic diagram of a code layout of a bootstrap program in the related art, and in conjunction with fig. 1, a mode of a first bootstrap+a second bootstrap+an application program is generally adopted for a scheme of upgrading the bootstrap program in the related art, where both the first bootstrap and the second bootstrap can be used as bootstrap programs of an ECU, and the first bootstrap can update the second bootstrap, but in an actual application process, there is a case that the first bootstrap needs to be updated, because the first bootstrap is in a start-up area, when the code amount of the first bootstrap is large, the probability of being brushed when updating the first bootstrap is large, and for an already packaged electronic control unit, if the first bootstrap is unexpected in the update process, the ECU may be down.
In order to solve the above problems, an embodiment of the present application provides a boot program update method. When the method is executed, a first code module of a first bootstrap program is firstly utilized to determine whether the first bootstrap program needs to be updated, and when the first bootstrap program needs to be updated, the first bootstrap program jumps to a second bootstrap program; later, a first bootstrap program update file of the first bootstrap program is determined in the second bootstrap program; the first bootstrap program updating file is used for updating the first bootstrap program; and finally, executing the updated first bootstrap program to update the second code module of the first bootstrap program by using the first bootstrap program update file of the first bootstrap program.
Therefore, the first code module of the first bootstrap program is used as a starting area, whether the first bootstrap program is updated or not is judged through the first code module of the first bootstrap program, and when the first bootstrap program needs to be updated, the second bootstrap program only updates the second code module of the first bootstrap program, but does not update the starting area, so that the possibility of update failure in the updating process of the first bootstrap program is reduced.

In order to make the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Fig. 2 is a flowchart of a method for updating a boot program according to an embodiment of the present application, and in conjunction with fig. 2, the method for updating a boot program according to an embodiment of the present application may include:
s201: a first code module of a first bootstrap program is utilized to determine whether the first bootstrap program needs to be updated, and when the first bootstrap program needs to be updated, the first bootstrap program jumps to a second bootstrap program.
In this embodiment, the first code module of the first boot program is used to boot the microcontroller to start and determine the execution program to be skipped, the second boot program is used to update the application program, and the application program is used to record the control service provided by the electronic controller. Fig. 3 is a schematic diagram of a bootstrap code layout provided in this embodiment of the present application, and in conjunction with fig. 3, the bootstrap code layout includes a first bootstrap program, a second bootstrap program and an APP (application program), where the first bootstrap program includes Block1 (first code module) and Block2 (second code module), it should be noted that, in this embodiment, the first code module is a complete program, and is composed of simple judgment type codes, and may be used to boot a microcontroller and determine an execution program to be skipped, and the first code module is fixedly stored in a sector area of a buffer area corresponding to the first bootstrap program, and when the first bootstrap program is updated, the program of the first code module is not updated.
In a specific embodiment, when the first code module of the first boot program determines whether the first boot program is updated, it needs to determine whether the second code module of the first boot program is complete, and when the second code module of the first boot program is complete, the step 201 of jumping from the first code module of the first boot program to the second code module of the first boot program determines whether the first boot program is updated, so that the step may specifically include: the first code module of the first bootstrap program judges whether the second code module of the first bootstrap program is complete; if the second code module of the first bootstrap program is complete, jumping from the first code module of the first bootstrap program to the second code module of the first bootstrap program; determining, by the second code module of the first bootstrap program, whether the first bootstrap program needs to be updated, and jumping from the second code module of the first bootstrap program to the second bootstrap program when the first bootstrap program needs to be updated. In this embodiment, since the first code module of the first bootstrap program only simply determines the skip code, when performing complex code operation, the first code module of the first bootstrap program skips to the corresponding target program, so that the target program is operated to achieve the purpose of determining whether the first bootstrap program is updated, and the effect of simplifying the first code module of the first bootstrap program is achieved.
In a specific embodiment, when the first code module of the first bootstrap program determines whether the first bootstrap program is updated, it needs to be determined whether the second code module of the first bootstrap program is complete, and when the second code module of the first bootstrap program is incomplete, it indicates that the first bootstrap program needs to be updated, in which case the first bootstrap program is directly skipped from the first code module of the first bootstrap program to the second bootstrap program so as to update the first bootstrap program through the second bootstrap program. Thus, the step 201 may specifically include: the first code module of the first bootstrap program judges whether the second code module of the first bootstrap program is complete; if the second code module of the first bootstrap program is incomplete, determining that the first bootstrap program needs to be updated, and jumping from the first code module of the first bootstrap program to the second bootstrap program. In this embodiment, when the second code module of the first bootstrap program is incomplete, the jump is directly from the first code module of the first bootstrap program to the second bootstrap program, so that the whole system is prevented from being brushed up due to the jump to the incomplete second code module, and the probability that the system cannot work due to the fact that the first bootstrap program is brushed up is reduced.
Alternatively, when the second code module of the first bootstrap is complete, then the second bootstrap may be updated by the first bootstrap. Specifically, the first bootstrap program determines whether the second bootstrap program update identifier exists in the public buffer area, and when the second bootstrap update identifier exists in the public buffer area, the second bootstrap program needs to be updated, and on the basis, the second code module of the first bootstrap program guides the second bootstrap program to update, and the first bootstrap program receives a second bootstrap program update file from the public buffer area, wherein the second bootstrap program update file is used for updating the second bootstrap program. Specifically, the second boot program is stored in the second partition, and when the second boot program is updated, the original data stored in the second partition is erased, and a second boot program update file is copied to the second boot partition to update the second boot program. It should be noted that, before erasing the original data stored in the second partition, the original data stored in the second partition may be copied to the common backup cache area so as to backup the original data.
In a specific embodiment, when the second bootstrap program is complete, that is, the second bootstrap program does not need to be updated, the first bootstrap program may be updated by using the second bootstrap program, so whether the first bootstrap update identifier exists may be detected by the second bootstrap, so that the second bootstrap program updates the first bootstrap program based on the first bootstrap program update identifier, so the determining, by the second code module of the first bootstrap program, whether the first bootstrap program needs to be updated may specifically include: the second code module of the first bootstrap program judges whether the second bootstrap program is complete; if the second bootstrap program is complete, the second bootstrap program detects the update identifier of the first bootstrap program to determine whether the first bootstrap program needs to be updated. In the above embodiment, when the first bootstrap program needs to be updated, the second bootstrap program is used to detect whether the update identifier of the first bootstrap program exists, the update identifier of the first bootstrap program is used to determine that the first bootstrap program needs to be updated, the operation of detecting the update identifier of the first bootstrap program is executed by the second bootstrap program, and the first bootstrap program is only responsible for determining the program to be skipped, so that the code amount of the first bootstrap program is reduced, the success rate of the update of the first bootstrap program is improved, and the system is prevented from being inoperable due to failure of the update of the first bootstrap program.
Specifically, after the application program has a command of updating the first bootstrap program, a common random storage area is marked, that is, a first bootstrap program update identifier exists in the common buffer area, when it is determined that the second bootstrap program is complete, the second bootstrap program jumps to the second bootstrap program from the second code module of the first bootstrap program, and the second bootstrap program can determine whether the first bootstrap program update identifier exists through the common buffer area, so that the step of detecting the first bootstrap program update identifier through the second bootstrap program to determine whether the first bootstrap program needs to be updated or not may specifically include: judging whether the first bootstrap program update identification exists in the public buffer area through the second bootstrap program, and determining that the first bootstrap program needs to be updated when the first bootstrap program update identification exists in the public buffer area.
In an alternative embodiment, the request for updating the first bootstrap program is directly sent before the system is powered up, at this time, the first code module of the first bootstrap program is used to determine whether the first bootstrap program needs to be updated, and when the first bootstrap program needs to be updated, the first bootstrap program jumps from the first bootstrap program to the second bootstrap program, and further includes: when the system is powered on and receives the first bootstrap program updating request, the system directly jumps to the second bootstrap program and is controlled to stay in the second bootstrap program so as to update the first bootstrap program by executing software reset or hardware reset.
S202: determining a first bootstrap update file of the first bootstrap in the second bootstrap; the first bootstrap update file is used for updating the first bootstrap.
In this embodiment, the second boot program may boot the first boot program, specifically, determine a first boot program update file of the first boot program in the second boot program, where the first boot program update file may be used to update the first boot program, that is, the first boot program update file is a file used to refresh the first boot program, and update the first boot program by determining a first boot program update file of the first boot program in the second boot program.
In an alternative embodiment, the second bootstrap program may also be used for updating the application program, where the update principle is the same as that of the first bootstrap program, and when the application program receives a request for updating the application program, a common random storage area is marked, that is, an application program update identifier may exist in the common buffer area, and the application program update file is obtained when the application program update identifier of the application program exists in the common buffer area by the second bootstrap program, so that the second bootstrap program updates the application program by using the application program update file.
S203: and executing the updated first bootstrap program to update the second code module of the first bootstrap program by using a first bootstrap program update file of the first bootstrap program.
In this embodiment, program data of a first boot program is stored in a first partition, the first boot program includes a first code module and a second code module, the program data of the first code module is stored in a first sub-partition of the first partition, and the program data of the second code module is stored in a second sub-partition of the first partition. When updating the first bootstrap program, only the second code module of the first bootstrap program is updated, but not the first code module of the first bootstrap program, in this embodiment, the first code module only retains a simple judgment logic code for determining the target program to be skipped, and does not include other complex functions, so the step 203 may specifically include: erasing the original data stored in the second sub-partition of the first partition; the first boot update file of the first boot is copied to the second sub-partition of the first partition to update the second code module of the first boot. In the above embodiment, when the first boot program is updated, only the second code module of the first boot program is updated, instead of updating the entire first boot program, so that the possibility that the first boot program is flushed is reduced, and the first code module of the first boot program is used as a starting area.
In a specific embodiment, only the second code module of the first boot can be swiped while the first boot is swiped. When the first guide is swiped through the second guide, software reset or hardware reset is firstly executed, and after a specific instruction is received, the program is blocked in the second guide code. That is, when the first boot program needs to be updated, after the first code module of the first boot program jumps to the second boot program, the second boot program needs to update the first boot program first, and the application program can be updated after the update of the first boot program is completed, so the first code module of the first boot program is utilized to determine whether the first boot program needs to be updated, and when the first boot program needs to be updated, after the first boot program jumps to the second boot program from the first boot program, the method further comprises: the second bootstrap program is prohibited from updating the application program. In this embodiment, when the first bootstrap program needs to be updated, the second bootstrap program is prohibited from updating the application program, so that the problem that the application program cannot be updated or cannot jump normally due to the fact that the first bootstrap program is not updated is prevented, and user experience is improved.
In the above embodiment, the first code module of the first bootstrap program is used as the boot area, and only the simple code is included, and when the second bootstrap program updates the first bootstrap program, only the second code module of the first bootstrap program is updated, but the boot area is not updated, so that the possibility of failure in updating the first bootstrap program in the updating process is reduced. Therefore, the situation that the first bootstrap program fails to update can be prevented to a certain extent, and the normal operation of the system is ensured.
