In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Referring to fig. 1 and 4, a first aspect of an embodiment of the present invention provides a Uboot upgrade method, including the following steps:
s101, after the single board is powered on, a timer is started to start timing, and whether a Uboot start flag bit is established or not is detected.
Specifically, one memory chip includes two regions, which are a secure region and a working region, respectively, the first Uboot starting region is a working region for storing a Uboot working program, the working region is also used for storing a program after Uboot upgrade, the second Uboot starting region is a secure region for storing a Uboot secure program, and the Uboot secure program includes a boot module and a board starting module. Under normal conditions, the Uboot security program stored in the security area will not make mistakes, and the single board can be ensured to be normally started, and if the program of the working area has a problem, the single board can also be normally started through the security area, wherein the program of the working area may be the same as or different from the program of the security area.
Specifically, after the board is powered on, the CPU starts from a boot module of the Uboot security area, starts a Timer to start timing, the Timer may be a Timer of hardware inside the CPU, and the CPU detects whether a Uboot start flag bit "Uboot _ STS" is established according to an algorithm, where, for the first power on of the board, the "Uboot _ STS" is not established, the "Uboot _ STS" has no value, and if the "Uboot _ STS" is established, the "Uboot _ STS" has a value.
S102, if the Uboot start flag bit is detected to be established, judging whether the value of the timing flag bit of the timer is a first preset value.
Specifically, if it is detected that the "Uboot _ STS" is already established, the "Uboot _ STS" has a value, it is then determined whether a value of a timing flag bit "Timer _ STS" of the Timer is a first preset value 1, that is, it is determined whether the Timer is timed out, if the value of the timing flag bit "Timer _ STS" is a second preset value 0, it indicates that the preset time is not exceeded, the subsequent steps are executed, if the value of the timing flag bit "Timer _ STS" is the first preset value 1, it indicates that the preset time is exceeded, and the single board starting module directly jumps to the security area to perform Uboot starting.
S103, if the value of the timing flag bit of the timer is not the first preset value, jumping to a first Uboot starting area or a second Uboot starting area in the storage module according to the value of the Uboot starting flag bit to start the Uboot.
Specifically, if the value of the timing flag "Timer _ STS" is not the first preset value 1, which indicates that the Timer is not overtime, then the boot region to be skipped may be determined according to the value of the Uboot start flag "Uboot _ STS", that is, a boot path is selected, if the value of the Uboot start flag "Uboot _ STS" is 01, the boot may be skipped to the second Uboot start region to start, specifically, the boot may be skipped to the single board start module of the secure area to start, if the value of the Uboot start flag "Uboot _ STS" is 02, the mirror image file in the first Uboot start region is verified to have an error, that is, the mirror image file in the working area is verified to have an error, specifically, the mirror image file in the working area may be verified by using a Cyclic Redundancy Check (CRC) verification method, if the mirror image file in the working area has no error, the boot is skipped to the first Uboot start region, namely jumping to a working area for starting, if the mirror image file in the first Uboot starting area has an error, jumping to the second Uboot starting area for Uboot starting. And if the value of the timing flag bit Timer _ STS is a first preset value 1, it indicates that the previous start has overtime and the start fails, so that the start directly jumps to the safe area start module for start.
And S104, after the Uboot is started successfully, stopping timing of the timer, setting a timing zone bit of the timer to be a second preset numerical value, and modifying the value of the Uboot starting zone bit according to the area where the Uboot is started successfully.
Specifically, after the Uboot is started successfully, the Timer may stop timing, set the value of the timing flag bit to a second preset value 0, which indicates that timing is not overtime, then modify the value of the Uboot starting flag bit according to the region where the Uboot is started successfully, change the value of the Uboot starting flag bit to a third preset value 02 if the region where the Uboot is started successfully is the first Uboot starting region, and change the value of the Uboot starting flag bit to a fifth preset value 01 if the region where the Uboot is started successfully is the second Uboot starting region, so that, in the subsequent starting process, the user may directly jump to the region where the Uboot can be started successfully according to the value of the Uboot starting flag bit to start.
And S105, after the Uboot is started, detecting whether a Uboot upgrading instruction exists.
Specifically, after the Uboot startup is completed, whether a Uboot upgrade instruction is received is detected, that is, whether update upgrade is to be performed on the Uboot program is determined.
And S106, if a Uboot upgrading instruction is detected, upgrading the Uboot program stored in the first Uboot starting area according to the Uboot upgrading instruction.
Specifically, if a Uboot upgrade instruction is detected, the Uboot program stored in the first Uboot startup area is upgraded, that is, the Uboot working program of the working area is updated and upgraded, and if no Uboot upgrade instruction is detected, the Uboot startup process is ended and other steps are not executed.
S107, detecting whether the Uboot program stored in the first Uboot startup area is upgraded successfully.
Specifically, whether the Uboot program stored in the first Uboot startup area succeeds or not can be detected by verifying the correctness of the program, a timer can be started to count when the upgrade is performed, and if the upgrade is not completed within the specified upgrade time, the upgrade is determined to fail.
S108, if the Uboot program stored in the first Uboot starting area is detected to be upgraded successfully, modifying the value of the Uboot starting flag bit to be a third preset value, re-executing the starting timer to start timing, and detecting whether the Uboot starting flag bit is established; and if the Uboot program stored in the first Uboot starting area is detected to be failed to be upgraded, quitting Uboot upgrading, and re-executing the step of detecting whether the Uboot upgrading instruction exists or not.
Specifically, if the Uboot program in the first Uboot starting area is successfully upgraded, the value of the Uboot starting flag bit is changed to a third preset value 02, during the step of re-executing the starting timer to start timing and detecting whether the Uboot starting flag bit is established, the reset CPU is required to be included, the Uboot program can be started in the subsequent starting process after upgrading, if the upgrading fails, the Uboot upgrading process is exited, and the step of detecting whether the Uboot upgrading instruction exists is re-executed.
As can be seen from the above description, in the embodiment of the present invention, the storage module is divided into two boot areas in which the Uboot program is stored, and when the boot area for upgrading the Uboot program fails to be upgraded, the Uboot program stored in the other boot area can be started, so that when the Uboot upgrade fails, normal startup of a product can be ensured, complexity of hardware design is reduced, and cost is saved.
Further, the Uboot upgrade method further includes:
and if the Uboot start flag bit is not established, initializing the value of the Uboot start flag bit to be a fourth preset value, and jumping to a second Uboot start area to start the Uboot.
Specifically, if it is detected that the Uboot start flag is not established, it indicates that the single board is powered on for the first time, the Uboot start flag has no value, the value of the Uboot start flag is initialized to be the fourth preset value 03, and the method directly jumps to a security area to perform Uboot start, so as to ensure normal start of the Uboot.
Further, the jumping to the first Uboot startup area or the second Uboot startup area in the storage module according to the value of the Uboot startup flag bit to perform Uboot startup includes:

And if the value of the Uboot start flag bit is a fifth preset value, jumping to a second Uboot start area in the storage module to start the Uboot.
Specifically, if the value of the Uboot start flag bit "Uboot _ STS" is a third preset value 02, it is verified whether the image file in the first Uboot start area has an error, that is, whether the image file in the working area has an error, specifically, a CRC check mode may be adopted for verification, if the image file in the working area has no error, it is skipped to the working area for Uboot start, and if the image file in the working area has an error, it is skipped to the second Uboot start area for Uboot start. And if the value of the Uboot start flag bit 'Uboot _ STS' is a fifth preset value 01, jumping to a second Uboot start area to start the Uboot, specifically, jumping to a single board start module of the security area to start the Uboot.
Further, the modifying the value of the Uboot starting flag bit according to the area where the Uboot is successfully started includes:
