Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a chip startup method, device, equipment and medium. Background Art

[0002] In the field of chip technology, chip firmware is usually stored in an electrically erasable programmable ROM (EEPROM) or FLASH (flash memory) chip. To ensure stable operation of the chip, users can use a specific refresh program to write the new firmware program into the EEPROM or FLASH chip to complete the firmware upgrade. To prevent the chip from being unable to start due to damage to a certain storage medium, the chip usually uses dual Flash or dual EEPROM to perform redundant backup of the firmware.

[0003] In traditional technology, when the chip firmware is upgraded, the new firmware program needs to be written into two Flash or EEPROMs. In addition, since most chips are designed to simplify, they are usually fixed to start from a certain Flash or EEPROM, and the startup medium cannot be flexibly specified, which makes the other storage medium idle for a long time. Although some chips can be started from a specified medium by means of external pins, this method not only requires the chip to lead out additional pins to indicate the startup medium, but also requires the design of external circuits to record the chip firmware upgrade status and input it to the chip through pins, which undoubtedly increases the design complexity and cost of the chip and external circuits. For this reason, the above technical problems urgently need to be solved by those skilled in the art. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a chip startup method, device, equipment and medium. The present application avoids the situation where a chip medium is idle for a long time, improves the utilization rate of the chip medium, simplifies the design of the chip and external circuits, and reduces the design complexity and cost.

[0018] Optionally, after executing the new firmware program to enable the chip to start up, the following steps are also included:

[0019] Determine whether the chip startup is successful;

[0020] If the chip is successfully started, the new firmware program is copied to other chip media other than the startup medium to achieve backup of the new firmware program.

[0021] Optionally, after executing the new firmware program to enable the chip to start up, the following steps are also included:

[0022] Trigger the start time timing operation;

[0023] If the chip starts successfully, the startup time timing operation is turned off;

[0024] If the chip fails to start, when the startup time is longer than the preset time threshold, a new firmware program obtained after the chip firmware upgrade is read from other chip media other than the startup medium, and the new firmware program is executed to realize chip startup.

[0025] Optionally, after reading a new firmware program obtained after the chip firmware is upgraded from other chip media other than the boot medium and executing the new firmware program to start the chip, the method further includes:

[0026] If the chip fails to start, the process jumps to the step of reading a new firmware program obtained after the chip firmware is upgraded from the startup medium until the chip starts successfully or the number of jumps meets a preset threshold.

[0027] Optionally, after updating the startup parameters in the target storage area of ​​all chip media, the method further includes:

[0028] Verify the integrity and security of the updated startup parameters;

[0038] It can be seen that the present application proposes a chip startup method, including: after the chip firmware is upgraded, updating the startup parameters in the target storage area of ​​all chip media; wherein the startup parameters in the target storage area represent the designated startup state of the corresponding chip medium, and the designated startup state represents whether to start from the corresponding chip medium; after the chip is powered on again, reading the startup parameters in the target storage area of ​​all chip media, so as to select the corresponding chip medium from all chip media as the startup medium based on the read startup parameters, and read the new firmware program obtained after the chip firmware is upgraded from the startup medium; executing the new firmware program to realize chip startup. In summary, it can be seen that after the chip firmware is upgraded, the system will update the startup parameters in the target storage area of ​​the chip medium, and these parameters are used to mark whether the corresponding chip medium is used as the startup medium. After the chip is powered on again, the startup medium will be selected from all chip media according to the startup parameters, and the upgraded new firmware program will be read from it and then executed, and finally the startup process of the chip will be completed.

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] In traditional technology, when the chip firmware is upgraded, the new firmware program needs to be written into two Flash or EEPROMs. In addition, since most chips are designed to simplify, they are usually fixed to start from a certain Flash or EEPROM, and the startup medium cannot be flexibly specified, which makes the other storage medium idle for a long time. Although some chips can be started from a specified medium by means of external pins, this method not only requires the chip to lead out additional pins to indicate the startup medium, but also requires the design of external circuits to record the chip firmware upgrade status and input it to the chip through pins, which undoubtedly increases the design complexity and cost of the chip and external circuits. For this reason, the above technical problems urgently need to be solved by those skilled in the art.

[0050] To this end, the embodiment of the present application proposes a chip startup solution, which can avoid the situation where a chip medium is idle for a long time, improve the utilization rate of the chip medium, simplify the design of the chip and external circuits, and reduce the design complexity and cost.

[0051] The present application embodiment discloses a chip startup method, see Figure 1 As shown, the method includes:

[0052] Step S11: after the chip firmware is upgraded, the startup parameters in the target storage area of ​​all chip media are updated; wherein the startup parameters in the target storage area represent the designated startup state of the corresponding chip medium, and the designated startup state represents whether to start from the corresponding chip medium.

[0053] In this embodiment, after the chip firmware is upgraded, the startup parameters in the target storage area of ​​all chip media are updated; wherein the startup parameters in the target storage area represent the designated startup state of the corresponding chip medium, and the designated startup state represents whether to start from the corresponding chip medium.

[0054] In this embodiment, the medium type is determined by reading the level state of the first chip pin, the redundancy mode is determined by reading the level state of the second chip pin, and all chip media are determined as the first chip medium and the second chip medium based on the redundancy mode. Among them, the redundancy mode includes dual-media redundancy or dual-partition redundancy. If the redundancy mode is dual-media redundancy, the first storage area of ​​the first chip medium is determined as the target storage area of ​​the first chip medium, and the first storage area of ​​the second chip medium is determined as the target storage area of ​​the second chip medium; if the redundancy mode is dual-partition redundancy, the first storage area of ​​the first chip medium is determined as the target storage area of ​​the first chip medium, and the second storage area of ​​the second chip medium is determined as the target storage area of ​​the second chip medium. In this way, the working mode and storage area are determined by simply reading the chip pin level state, without the need for complex hardware circuits or additional sensors, simplifying the hardware design, and reducing hardware costs and system complexity.

[0055] Exemplarily, the media include Flash (flash memory), EEPROM (Electrically ErasableProgrammable Read-Only Memory) and SD card, dual media redundancy is dual Flash (Flash0, Flash1), dual EEPROM (EEPROM0, EEPROM1), etc., dual partition redundancy is single Flash dual partition (upper half, lower half), etc. For dual Flash, Flash0 is the first chip medium, Flash1 is the second chip medium, for dual EEPROM, EEPROM0 is the first chip medium, EEPROM1 is the second chip medium. For single Flash dual partition, the upper half is the first chip medium, and the lower half is the second chip medium. Furthermore, the chip pin design remains unchanged, and a redundant chip is usually used, and 3 chip pins are designed to indicate the current chip working environment. 2 chip pins (i.e., the first chip pin, boot_mode) are used to indicate which boot medium is currently used. For example, boot_mode=0x00 means Flash boot; boot_mode=0x01 means EEPROM boot; boot_mode=0x10 means SD card boot. One chip pin (i.e., the second chip pin, boot_num) can be used to indicate the redundancy mode. For example, boot_num=0x0 means dual Flash / EEPROM / SD card redundancy; boot_num=0x1 means single and dual Flash / EEPROM / SD card dual partition redundancy. For further information, see Figure 2 and Figure 3 As shown, Figure 2 This is a schematic diagram of the dual-mirror address space division of a single NOR Flash. Figure 3 This is a diagram of the division of the dual NOR Flash address space. The first storage area (Paramter_ROM_P0) is used to store the startup parameters of the upper half (single flash startup) or flash (dual flash), which is read by the ROM program and stored in a fixed position of the NOR Flash; the second storage area (Paramter_ROM_P1) is used to store the startup parameters of the lower half (single flash startup), which is read by the ROM program and stored in a fixed position of the NOR Flash. That is, the P0 and P1 areas are used in the single Flash dual-image startup, and only the P0 area is used in the dual Flash startup. The new firmware program includes SPL, UBoot and Kernel: it is the normal firmware program of the chip. It should be pointed out that dual media redundancy and dual partition redundancy are both used for redundant backup. Each medium can be used as a separate startup medium to store data separately.

[0056] Based on this, in this embodiment, updating the startup parameters in the target storage areas of all chip media includes: updating the startup parameters in the target storage areas of the first chip medium and the second chip medium.

[0057] Step S12: After the chip is powered on again, the startup parameters in the target storage area of ​​all chip media are read, so as to select the corresponding chip medium from all chip media as the startup medium based on the read startup parameters, and read the new firmware program obtained after the chip firmware is upgraded from the startup medium.

[0058] It can be seen that after each firmware upgrade is completed, the startup parameters need to be updated at the same time to determine which chip medium to boot from next time. Furthermore, after the chip is powered on again, the startup parameters in the target storage area of ​​all chip media are read, so that the corresponding chip medium is selected as the startup medium from all chip media based on the read startup parameters, so as to achieve the specified media startup. Specifically, this embodiment reads the startup parameters in the target storage area of ​​the first chip medium and the second chip medium, so that the corresponding chip medium is selected as the startup medium from the first chip medium and the second chip medium based on the read startup parameters. In this way, the present application is no longer fixed to start from a certain chip medium, but can flexibly switch chip media, avoiding the situation where a certain chip medium is idle for a long time, and improving the utilization rate of the chip medium.

[0059] For example, taking dual Flash boot as an example, As shown in Table 1, valid indicates the specified startup state corresponding to the startup parameter. To start the effective state, Invalid startup state, except and All others are in error status.

[0060] Table 1

[0061]

[0062] Step S13: Execute the new firmware program to start the chip.

[0063] In this embodiment, the first firmware program (SPL program) in the new firmware program is migrated to the static random access memory (SRAM), and it is determined whether the first firmware program is safe and reliable. If the first firmware program is safe and reliable, the first firmware program is executed, and the second firmware program (UBoot and Kernel) in the new firmware program is migrated to the static random access memory, and then the second firmware program is executed to realize chip startup.

[0064] Further, it is determined whether the chip startup is successful; if the chip startup is successful, the new firmware program is copied to other chip media other than the startup medium to achieve backup of the new firmware program.

[0065] Furthermore, the startup duration timing operation is triggered. If the chip starts successfully, the startup duration timing operation is turned off; if the chip fails to start, when the startup duration is greater than the preset duration threshold, the new firmware program obtained after the chip firmware upgrade is read from other chip media other than the startup medium, and the new firmware program is executed to realize chip startup; if the chip fails to start, jump to the step of reading the new firmware program obtained after the chip firmware upgrade from the startup medium until the chip starts successfully or the number of jumps meets the preset threshold. For example, after the chip is powered on, it will first read the startup parameters from medium 1, and then read the startup parameters from medium 2. By comparing the startup parameters in the two media, it is decided which medium to start from. Assuming that it is decided to start from medium 0, the firmware program will be moved from medium 0 to start execution, and WDT (Watch-dog Timer) will be started at the same time. If the startup is successful, the WDT will be turned off. If the startup fails, the WDT cannot be turned off. After the WDT times out, the program will be moved from medium 1 to start execution, and the WDT will be restarted at the same time. If the startup is successful, the WDT will be turned off. If the startup fails, the WDT cannot be turned off. After the WDT times out, it will jump to medium 0 to execute the startup process. In some embodiments, the jump is up to 3 times. If the startup fails, it is considered that there is a problem with the firmware and the chip cannot be started. In this way, by setting a switching mechanism when the startup fails, multiple attempts to start from different media are made, which increases the probability of successful startup of the chip and reduces the situation where the startup cannot be caused by a single medium failure.

[0066] Furthermore, the integrity and security of the updated startup parameters are verified; if the verification passes, the historical startup parameter erasure operation in the target storage area is triggered. In this way, it is ensured that the startup will not fail due to update failure, and the reliability and stability of chip startup are improved.

[0067] Figure 4A schematic diagram of a secure boot process is disclosed, including: (1) powering on the chip; (2) reading the chip pin status and accessing the read-only memory; (3) reading the startup parameters of the first chip medium; (4) resetting the chip and configuring the serial peripheral interface controller; (5) reading the startup parameters of the second chip medium; (6) judging whether to boot from the first chip medium. If yes, reset the chip again and configure the serial peripheral interface controller; if no, proceed to the next step; (7) regardless of whether booting from the first chip medium, judging whether the SPL is safe and reliable to achieve secure boot, if not, stop booting, if reliable, execute SPL (Secondary Program Loader) and migrate the Uboot (Universal Boot Loader) program to In the Synchronous Dynamic Random Access Memory (SDRAM), the CPU (Central Processing Unit) The UBoot program starts to execute at the specified address; further, Uboot initializes related hardware, obtains the storage location information and size information of the Kernel program (kernel program), and migrates the Kernel to SDRAM. The CPU starts to execute the Kernel program from the specified address of SDRAM, and finally completes the chip startup.

[0068] Figure 5 A schematic diagram of multi-bit default upgrade from flash0 is disclosed. Assuming that Flash1 needs to be upgraded first, The parameters of the area tell to boot from Flash1 and then upgrade Flash0. The parameters of the area tell to boot from Flash0. The entire process realizes the startup of the specified chip medium through the change of the startup parameter valid, and then realizes the upgrade of Flash1 and Flash0 in sequence.

[0069] Figure 6 A schematic diagram of Flash0 and Flash1 address space division and startup process is disclosed, including the first startup process, Web remote upgrade process, and non-first startup process. First startup process: The chip is powered on, and the ROM program reads the chip pin status and the Flash0 , configure the SOC (System on Chip), reset the QSPI (Quad Serial Peripheral Interface) controller, and then read the Flash1 . Determine the boot medium, if it is unsafe, stop booting, if it is safe, execute Program, read Get the number of boot times and other information, migrate and execute SPL and other boot programs, then migrate and execute U-boot, etc., to complete the Flash0 boot. Web remote upgrade process: remotely upgrade Flash through the Web, including PRE, SPL, U-boot, Kernel, etc. After the upgrade is completed, update Flash1 and Flash0 in turn. , The valid flag is 0xA5. Non-first boot process: The chip is powered on, and the ROM program reads the pin status and Flash0 , then read Flash1 , determine the boot media and security. If it is safe, execute program, obtain the boot times and other information, migrate and execute the SPL program, and then migrate and execute the U-boot program to complete the Flash boot.

[0070] This application implements the designated medium startup after the chip firmware upgrade is completed without using additional chip pins and peripheral update circuits. That is, without the need for additional chip pins and peripheral circuits, the chip can be specified to start from Flash0 or Flash1, reducing the complexity of chip design and the complexity of peripheral circuit design. At the same time, after writing new firmware to a certain Flash, it can be specified to start from this new firmware Flash. After the startup is completed, the new firmware will be automatically backed up to another Flash for redundant backup.

[0071] Furthermore, during the operation of the chip, the status of each chip medium and partition is monitored in real time. For example, the integrity of the stored data is checked. If the data checksum of a chip medium or partition is found to be inconsistent with the pre-calculated data, it is determined that the area may have a fault. At the same time, the read and write operation response time of the chip medium is monitored. If the read and write response time of a chip medium exceeds the preset threshold, it is considered that the chip medium may have performance degradation or failure. Further, when a chip medium or partition is detected to have a fault, the chip control module will decide whether to perform redundant switching based on the current redundancy mode and fault condition. If the dual-media redundancy mode is currently used and a fault is detected in the first chip medium, it will automatically switch to the second chip medium for data read and write operations. At the same time, the fault information is recorded in the chip log to facilitate subsequent troubleshooting and maintenance.

[0072] It can be seen that the present application proposes a chip startup method, including: after the chip firmware is upgraded, updating the startup parameters in the target storage area of ​​all chip media; wherein the startup parameters in the target storage area represent the designated startup state of the corresponding chip medium, and the designated startup state represents whether to start from the corresponding chip medium; after the chip is powered on again, reading the startup parameters in the target storage area of ​​all chip media, so as to select the corresponding chip medium from all chip media as the startup medium based on the read startup parameters, and read the new firmware program obtained after the chip firmware is upgraded from the startup medium; executing the new firmware program to realize chip startup. In summary, it can be seen that after the chip firmware is upgraded, the system will update the startup parameters in the target storage area of ​​the chip medium, and these parameters are used to mark whether the corresponding chip medium is used as the startup medium. After the chip is powered on again, the startup medium will be selected from all chip media according to the startup parameters, and the upgraded new firmware program will be read from it and then executed, and finally the startup process of the chip will be completed. By updating the startup parameters, the present application enables the chip to select the corresponding chip medium as the startup medium from all chip media according to the startup parameters when it is powered on again. In this way, it is no longer fixed to start from a certain chip medium, but can be switched flexibly, avoiding the situation where a certain chip medium is idle for a long time, and improving the utilization rate of the chip medium. Furthermore, the present application selects the boot medium by reading the boot parameters, without the need to lead out additional pins, and without the need to design a special external circuit to record and transmit firmware upgrade status information, which simplifies the design of the chip and external circuit, and reduces the design complexity and cost.

[0073] Correspondingly, the present application also discloses a chip startup device, see Figure 7 As shown, the device comprises:

[0074] The startup parameter update module 11 is used to update the startup parameters in the target storage area of ​​all chip media after the chip firmware is upgraded; wherein the startup parameters in the target storage area represent the designated startup state of the corresponding chip medium, and the designated startup state represents whether to start from the corresponding chip medium;

[0075] The boot medium selection module 12 is used to read the boot parameters in the target storage area of ​​all chip media after the chip is powered on again, so as to select the corresponding chip medium from all chip media as the boot medium based on the read boot parameters, and read the new firmware program obtained after the chip firmware is upgraded from the boot medium;

[0076] The chip startup module 13 is used to execute the new firmware program to realize chip startup.

[0078] It can be seen that the present application proposes a chip startup method, including: after the chip firmware is upgraded, updating the startup parameters in the target storage area of ​​all chip media; wherein the startup parameters in the target storage area represent the designated startup state of the corresponding chip medium, and the designated startup state represents whether to start from the corresponding chip medium; after the chip is powered on again, reading the startup parameters in the target storage area of ​​all chip media, so as to select the corresponding chip medium from all chip media as the startup medium based on the read startup parameters, and read the new firmware program obtained after the chip firmware is upgraded from the startup medium; executing the new firmware program to realize chip startup. In summary, it can be seen that after the chip firmware is upgraded, the system will update the startup parameters in the target storage area of ​​the chip medium, and these parameters are used to mark whether the corresponding chip medium is used as the startup medium. After the chip is powered on again, the startup medium will be selected from all chip media according to the startup parameters, and the upgraded new firmware program will be read from it and then executed, and finally the startup process of the chip will be completed. By updating the startup parameters, the present application enables the chip to select the corresponding chip medium as the startup medium from all chip media according to the startup parameters when it is powered on again. In this way, it is no longer fixed to start from a certain chip medium, but can be switched flexibly, avoiding the situation where a certain chip medium is idle for a long time, and improving the utilization rate of the chip medium. Furthermore, the present application selects the boot medium by reading the boot parameters, without the need to lead out additional pins, and without the need to design a special external circuit to record and transmit firmware upgrade status information, which simplifies the design of the chip and external circuit, and reduces the design complexity and cost.
