Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In order to solve the problem that in a product testing link or in a front-stage use process, a Bootloader program customized by a product is easy to damage due to byte jump of a Flash memory, and further the starting abnormality of the electronic equipment product is caused, the invention designs and provides a Boot method of the electronic equipment, which is particularly suitable for small wearable equipment, such as a smart wristband or a smart watch product. Such products typically employ a system-on-a-chip (SoC) based architecture to reduce the complexity of employing discrete electronic components in terms of electrical compatibility and testing, while controlling overall power consumption. In a system on chip (SoC), not only one processor is built in, but also analog and digital circuits that can implement most basic functions, such as built-in connection devices, power manager, bluetooth subsystem, antenna, clock, etc., are packaged. Based on the processor selected, a system-on-chip (SoC) is configured with a system-on-chip boot loader (SoC Bootloader). The system on chip bootstrap program is a small program executed before the system on chip runs, and through the small program, the hardware equipment can be initialized, and a mapping table of the memory space is built, so that a proper system software and hardware environment is built, and preparation is made for finally calling the kernel of the operating system. The system on chip boot program can be started from the storage medium, further boot the operating system, and support the serial port and the Ethernet interface.
As introduced in the background section, the system-on-chip bootstrap program is generally simpler, and in order to meet the requirements of the production of the wearable device product, especially to fulfill the requirements of Flash upgrading, erasing and writing of the mark, a local bootstrap program for customizing the product, namely a custom Bootloader, is usually created in a specific area in a Flash memory which can be in communication connection with the system-on-chip or a Flash memory built in the system-on-chip, and the local bootstrap program further fulfills the requirements of upgrading, erasing and writing of the Flash memory. In order to avoid a Boot failure caused by a local Boot error due to Flash byte transitions, the Boot method of the electronic device provided by the invention comprises a plurality of steps as shown in fig. 1.
Referring to fig. 1, in step S101, a system on chip bootstrap program reads target data of a target area in a memory. The memory referred to herein may be a Flash memory built in the system on chip, or may be an external Flash memory communicatively connected to the system on chip, in which a local boot program is configured. Since the local boot program is typically placed at the bottom or top of the memory, the target area is preferably the bottom or top area of the memory and may be set according to a reset vector in a processor in the system-on-chip.
Step S102, unlike the direct jump in the prior art, in the present invention, the target data is first checked.
Step S103, the target data is successfully checked, namely, the target area of the memory has no hardware error or software error.
Step S104, after the result of successful verification of the target data is obtained, the system on chip bootstrap program is started normally and jumps to execute the local bootstrap program in the memory. The local boot program is started and the system operates normally.
In another case, as shown in step S105, if the target data check fails, it indicates that there is a bad area or a bad block in the memory, or that there is a data error such as bit inversion, byte transition, etc.
Step S106, after the target data check fails, the method jumps to enter a repair mode. The system on chip bootstrap program jumps to the upgrade program and upgrades the memory automatically or after waiting for manual confirmation by the user. When the memory is upgraded, the memory is in communication connection with an external device (for example, through a serial interface), and a repair file containing a local boot program is rewritten in the memory, so that the detection and correction of error data in the memory are realized. If a certain bit corresponding to a physical storage unit of the memory is physically changed, the upgrade program automatically writes a repair file containing the local boot program into a fault-free area, so that the electronic equipment product is ensured to be started normally under the guidance of the local boot program.
According to the Boot method of the electronic equipment, the target data of the target area in the memory is firstly read through the system-on-chip bootstrap program during operation, and the target data is checked before the local bootstrap program is executed in a jumping mode, so that the correctness of the data in the memory is screened. And when the verification is successful, the local boot program in the memory is jumped to execute, and when the verification is failed, the method enters a repair mode to repair the data in the memory, so that the starting failure caused by the data error or physical damage of the Flash memory is avoided.
As shown in fig. 2, a Boot method of an electronic device with more various functions is provided. Specifically, before the system on chip bootstrap program reads the target data of the target area in the memory, the Boot method of the electronic device further includes the steps of Boot self-checking and upgrading mode judging.
In step S201, the electronic device is powered on. After the electronic device is powered on, the processor starts to execute the program from a set address, which is determined by the design of the processor, and the ROM or Flash in the system on chip is mapped to the address, and the system on chip boot program is stored in the corresponding Flash storage location. After the electronic device is powered on, the processor automatically executes the system-on-chip bootstrap program.
In step S202, the system on chip bootstrap program executes a boot self-test procedure to determine whether all components in the system on chip can operate normally.
Step S203, the power-on self-test is normal.
In step S204, the system on chip bootstrap program determines whether a hardware upgrade signal is received. The hardware upgrade signal is preferably generated by a manual operation by a user or tester and may be embodied in the form of an upgrade flag bit.
In step S205, if the hardware upgrade signal is not received, the system on chip bootstrap program reads the target data of the target area in the memory. Consistent with the first embodiment, the memory referred to herein may be a Flash memory built in the system on chip, or may be an external Flash memory communicatively connected to the system on chip. The bottom or top of the memory is configured with a local boot program. The target area is preferably the bottom or top area of the memory and is set according to a reset vector in a processor in the system-on-chip.
Step S206, checking the target data.
Step S207, the target data check is successful, which indicates that the target area of the memory has no hardware error or software error.
Step S208, after the result of successful verification of the target data is obtained, the system on chip bootstrap program is started normally and jumps to execute the local bootstrap program in the memory. The local boot program is started and the system operates normally.
In another case, as shown in step 209, the target data verification fails, indicating that there is a bad region or block of memory, or that there is a data error such as bit inversion, byte transitions, etc.
Step S210, after the target data check fails, the method jumps to a repair mode. The system on chip bootstrap program jumps to execute the upgrade program, and repairs the memory automatically or after waiting for manual confirmation by the user. When the memory is repaired, the memory is in communication connection with an external device (for example, through a serial interface), and a repair file containing a local boot program is rewritten in the memory, so that the detection and correction of error data in the memory are realized. If a certain bit corresponding to a physical storage unit of the memory is physically changed, the upgrade program automatically writes a repair file containing the local boot program into a fault-free area, so that the electronic equipment product is ensured to be started normally under the guidance of the local boot program.
Step S211, if the system on chip bootstrap program judges that the hardware upgrade signal is received before the system on chip bootstrap program reads the target data of the target area in the memory, the system on chip bootstrap program enters an upgrade mode, jumps to execute the upgrade program, and upgrades the memory automatically or after waiting for the manual confirmation of the user. When the memory is upgraded, the memory is communicatively connected to an external device (e.g., via a serial interface), and the upgrade file is rewritten into the memory. The upgrade file and the repair file can be the same, namely the upgrade repair file containing the latest version of the local boot program, and the program is iteratively updated in time while keeping normal operation, so that miniaturization of the program code is kept.
Fig. 3 is a flowchart showing the verification of the target data of the target area. The method specifically comprises the following steps:
step S301, reading target data of a target area in a memory, and calculating a calculation check value N of the target data;
in step S302, a preset check value N' of target data of a target area stored in advance in the memory is read.
In step S303, it is determined whether the calculated check value N is consistent with the preset check value N'.
Step S304, if the calculated check value N is consistent with the preset check value N', the target data is successfully checked.
In step S305, if the calculated check value N is inconsistent with the preset check value N', the target data check fails.
Wherein the preset check value N' is preferably a CRC check value of 1 to 4 bytes at the end of the target area in the memory. After the target data of the target area is read, calculating CRC check values of 1-4 bytes at the tail end of the target area as a calculated check value N, calling the CRC check values of 1-4 bytes at the tail end of the target area stored in advance in a memory, which are already calculated and stored based on the same algorithm as a preset check value N ', and comparing the calculated check value N with the preset check value N' to obtain a conclusion that the target data is successfully checked or the target data is failed to be checked.
The preset check value N' may also be a parity value of 1 to 4 bytes at the end of the target area in memory. After the target data of the target area is read, calculating the parity check value of 1 to 4 bytes at the tail end of the target area as a calculated check value N, calling the parity check value of 1 to 4 bytes at the tail end of the target area stored in advance in the memory, which is already calculated and stored based on the same algorithm as a preset check value N ', and comparing the calculated check value N with the preset check value N' to obtain the conclusion that the target data is successfully checked or the target data is failed to be checked.
