Therefore, when the firmware of the storage apparatus 200 has an error, that is, the operating system 210 or the firmware 220 of the storage apparatus 200 is damaged, the operating system 210 or the firmware 220 needs to be upgraded.
Referring to FIG. 2, in one embodiment of the invention, the memory device 200 may include a Normal Mode (Normal Mode) and a Debug Mode (Debug Mode). When the firmware of the storage device 200 is not in error, that is, the storage device 200 is in the normal mode, the processor (CPU) 300 of the host can extract information to be updated that is temporarily stored in a Dynamic Random Access Memory (DRAM) 400, and transmit the information to the storage device 200 through the interface, so as to update the firmware of the storage device 200. When the operating system 210 or the firmware 220 of the storage apparatus 200 reports an error, that is, the storage apparatus 200 is in the debug mode, the operating system 210 or the firmware 220 of the storage apparatus 200 may be updated by the upgrading apparatus 100. The upgrade apparatus 100 may include a micro control unit 110, a network unit 120, and an interface unit 130, and the micro control unit 110, the network unit 120, and the interface unit 130 may be integrated on a single circuit board.

The wireless network WIFI module is an embedded module which converts a serial port or a TTL level into a level meeting WIFI wireless network communication standard, and a wireless network protocol IEEE802.11b.g.n protocol stack and a TCP/IP protocol stack are arranged in the wireless network WIFI module. The micro control unit 110 may be connected to a cloud or a server through a wireless network WIFI module.
Referring to fig. 2, in one embodiment of the invention, the interface unit 130 may be an eMMC Debug Port (Debug Port), which refers to process-specific software or application-specific software constructs used as communication endpoints by the transport layer protocols of the internet protocol suite, such as User Datagram Protocol (UDP) and Transmission Control Protocol (TCP), and a particular network Port is identified by its number (commonly referred to as a Port number), an IP address associated with the Port, and a type of transport protocol used for communication. The interface unit 130 may be communicatively coupled to a communication interface 230 on the host, the communication interface 230 may be communicatively coupled to the storage device 200, and the interface unit 130 may communicate with the storage device 200. The mcu 110 may transmit the operating system information and the firmware information to be updated, which are temporarily stored, to the storage apparatus 200 through the standard eMMC communication protocol, so as to update the firmware of the storage apparatus 200. The interface unit 130 is removably connected to the communication interface 230 on the host. When the upgrade apparatus 100 needs to be used, the interface unit 130 on the upgrade apparatus 100 may be connected with the communication interface 230 on the host computer to enable the upgrade apparatus 100 to upgrade the firmware of the storage apparatus 200. When the firmware upgrade of the storage device 200 is completed, the upgrade device 100 may be separated from the communication interface 230 on the host, and the storage device 200 may be normally used.
Referring to fig. 3, the present invention further provides a method for upgrading a firmware of a storage device, where the upgrading method is applicable to the upgrading device 100, and when the firmware of the storage device 200 needs to be upgraded, the firmware of the storage device 200 can be upgraded by the upgrading method, and the upgrading method includes the following steps:
s10, acquiring information to be updated;
step S20, switching the working modes of the storage device according to the firmware condition of the storage device, wherein the working modes comprise a normal mode and a debugging mode;
step S30, when the storage device is in a normal mode, transmitting information to be updated to the storage device through a processor of the host so as to update the firmware of the storage device;
step S40, when the storage device is in a debugging mode, transmitting information to be updated to the micro control unit through the network unit, and temporarily storing the information in the micro control unit;
and S50, the micro control unit transmits the information to be updated into the storage device through the interface unit so as to update the firmware of the storage device.
In one embodiment of the present invention, when step S10 is performed, the information to be updated is acquired. Specifically, the information to be updated may include operating system information to be updated and firmware information to be updated. The operating system information to be updated may update the operating system 210 of the storage apparatus 200, and the firmware information to be updated may update the firmware 220 of the storage apparatus 200. When the storage apparatus 200 needs to be updated, the operating system 210 of the storage apparatus 200 may need to be updated, the firmware 220 of the storage apparatus 200 may need to be updated, and both the operating system 210 and the firmware 220 of the storage apparatus 200 may need to be updated. Therefore, according to the firmware condition of the storage device 200, the corresponding information to be updated may be further obtained, and the information to be updated may only include the operating system information to be updated, may also only include the firmware information to be updated, and may also include both the operating system information to be updated and the firmware information to be updated.
Referring to fig. 4, in an embodiment of the invention, when step S20 is executed, the operating mode of the storage device is switched according to the firmware condition of the storage device. Specifically, step S20 may include the following steps:
s21, judging whether data in an operating system and/or firmware of the storage device are error-reported or not;
s22, when the data in the operating system and the firmware of the storage device are not reported in error, the storage device is in a normal mode;
and step S23, when the data in the operating system and/or the firmware of the storage device is wrong, switching the storage device from the normal mode to the debugging mode.
In an embodiment of the present invention, when the steps S21, S22 and S23 are executed, specifically, when the firmware of the storage device 200 needs to be updated, it needs to be determined whether the storage device 200 can operate normally, and further, according to the operating condition of the storage device 200, different updating manners may be selected to update the firmware of the storage device 200. When the storage device 200 is capable of normal operation, i.e., the storage device 200 is in a normal mode, the storage device 200 may communicate with the processor 300 of the host. The information to be updated may be transmitted into the storage device 200 by the processor 300 of the host to update the firmware of the storage device 200 while the storage device 200 is in the normal mode. When the storage device 200 cannot work normally, i.e. when data errors occur in the operating system and/or firmware of the storage device 200, the storage device 200 cannot communicate with the processor 300 of the host, and the processor 300 of the host cannot directly upgrade the firmware of the storage device 200. At this time, it is necessary to switch the operation mode of the memory device 200 and switch the memory device 200 from the normal mode to the debug mode. In the debug mode, information to be updated may be transmitted into the storage apparatus 200 through the upgrade apparatus 100 to update the firmware of the storage apparatus 200.
Referring to fig. 5, in one embodiment of the present invention, when step S30 is executed, that is, when the storage device is in the normal mode, information to be updated is transmitted to the storage device through the processor of the host, so as to update the firmware of the storage device. Specifically, step S30 may include the following steps:
s31, transmitting the information to be updated to a storage device through a processor of the host;
step S32, comparing the version number of the information to be updated with the firmware version number of the storage device, and judging whether the version number of the information to be updated is correct;
step S33, if the version number of the information to be updated is correct, upgrading the firmware of the storage device according to the information to be updated;
step S34, if the version number of the information to be updated is incorrect, the storage device sends a version error instruction to a processor of the host.
In an embodiment of the invention, when the steps S31, S32, S33 and S34 are executed, specifically, when the storage device 200 is in the normal mode, at this time, the storage device 200 and the processor 300 of the host can normally communicate, and the processor 300 of the host can transmit the information to be updated into the storage device 200 to update the firmware of the storage device 200. When the storage device 200 is updated, in order to prevent the firmware version of the updated storage device 200 from deviating, it is necessary to determine the version number of the information to be updated, compare the version number of the information to be updated with the firmware version number of the storage device 200, and determine whether the version number of the information to be updated is correct. The version number is an identification number of the version, and each operating system has a version number, so that the version number can make a user know whether the used operating system is the latest version and the functions and facilities provided by the operating system.
In an embodiment of the present invention, when it is required to determine whether the version number of the information to be updated is correct, the version number of the information to be updated needs to be compared with the firmware version number of the storage device 200. For example, the version number of the operating system 210 of the storage apparatus 200 is 1.1.1.2, the version number of the operating system information to be updated in the information to be updated is 1.1.1.3, and the version of the operating system information to be updated is higher than the version of the operating system 210 of the storage apparatus 200, so that the version number of the operating system information to be updated in the information to be updated can be determined to be correct. If the version number of the os information to be updated in the information to be updated is 1.1.1.0, or 1.1.1.1, or 1.1.1.2, the version number of the os information to be updated is lower or the same as the version number of the os 210 in the storage device 200, and thus the version number of the os information to be updated in the information to be updated may be determined to be incorrect.
In an embodiment of the present invention, for another example, the version number of the firmware information to be updated in the information to be updated may also be compared with the version number of the firmware 220 of the storage apparatus 200. For example, the version number of the firmware 220 in the storage apparatus 200 is 2.1.1.2, the version number of the firmware information to be updated in the information to be updated is 2.1.1.3, and the version of the firmware information to be updated in the information to be updated is higher than the version of the firmware 220 in the storage apparatus 200, so that the version number of the firmware information to be updated in the information to be updated can be determined as correct. If the version number of the firmware information to be updated in the information to be updated is 2.1.1.0, or 2.1.1, or 2.1.1.2, the version number of the firmware information to be updated in the information to be updated is lower or the same as the version number of the firmware 220 in the storage device 200, and therefore the version number of the firmware information to be updated in the information to be updated may be determined to be incorrect.
In one embodiment of the present invention, when only the operating system information to be updated exists in the information to be updated, the version number of the operating system information to be updated may be compared with the version number of the operating system 210 of the storage apparatus 200. When the version number of the operating system information to be updated is correct, the operating system 210 of the storage apparatus 200 may be updated. When the version number of the operating system information to be updated is incorrect, the storage device 200 may send a version error instruction to the processor of the host to indicate that the version of the operating system information to be updated sent by the processor of the host is too low to be downloaded again.
In one embodiment of the present invention, when only the firmware information to be updated exists in the information to be updated, the version number of the firmware information to be updated may be compared with the version number of the firmware 220 of the storage device 200. When the version number of the firmware information to be updated is correct, the firmware 220 of the storage apparatus 200 may be updated, and when the version number of the firmware information to be updated is incorrect, the storage apparatus 200 may send a version error instruction to the processor 300 of the host to indicate that the version of the firmware information to be updated sent by the processor 300 of the host is too low and needs to be downloaded again.
In an embodiment of the present invention, when the information to be updated includes the operating system information to be updated and the firmware information to be updated at the same time, the version number of the operating system information to be updated needs to be compared with the version number of the operating system 210 of the storage apparatus 200, and the version number of the firmware information to be updated needs to be compared with the version number of the firmware 220 of the storage apparatus 200. When the version number of the operating system information to be updated is incorrect or the version number of the firmware information to be updated is incorrect, at this time, the storage device 200 may send a version error instruction to the processor 300 of the host to indicate that the version of the operating system information to be updated or the firmware information to be updated sent by the processor 300 of the host is too low, and needs to be downloaded again. The firmware of the storage device 200 can be updated by the information to be updated only when the version number of the operating system information to be updated and the version number of the firmware information to be updated are correct at the same time.
In one embodiment of the present invention, when step S40 is executed, i.e. when the storage device is in the debug mode, the information to be updated is transmitted to the micro control unit through the network unit and is temporarily stored in the micro control unit. Specifically, when the firmware of the storage apparatus 200 is lost or damaged, the storage apparatus 200 needs to be switched from the normal mode to the debug mode. The memory device 200 can be brought into a debug mode by manually switching the switch. The memory device 200 may also be controlled by the host's processor 300 to enter a debug mode. At this time, the storage device 200 may communicate with the upgrade device 100, and the mcu 110 may download the information to be updated through the network unit 120 and temporarily store the information in the mcu 110.
Referring to fig. 6, in an embodiment of the present invention, when step S50 is executed, the mcu transmits information to be updated to the storage device through the interface unit, so as to update the firmware of the storage device. Specifically, step S50 may include the following steps:
s51, the micro control unit transmits the information to be updated to an interface unit through a standard eMMC communication protocol;
step S52, the interface unit transmits the information to be updated to the storage device;
step S53, updating the firmware of the storage device by the information to be updated.
In one embodiment of the present invention, when steps S51, S52 and S53 are executed, specifically, after the information to be updated is temporarily stored in the micro control unit 110, since the micro control unit 110 communicates with the storage device 200 through the interface unit 130, the micro control unit 110 may transmit the information to be updated into the interface unit 130 through the standard memory eMMC communication protocol, and the interface unit 130 transmits the information to be updated into the storage device 200, so as to update the firmware of the storage device 200 through the information to be updated.
Referring to fig. 7, in an embodiment of the present invention, when step S53 is executed, the firmware of the storage device is updated by the information to be updated. Specifically, step S53 may include the following steps:
step S531, comparing the version number of the information to be updated with the firmware version number of the storage device, and judging whether the version number of the information to be updated is correct;
step S532, if the version number of the information to be updated is incorrect, the storage device sends a version error instruction to the micro control unit;
step S533, if the version number of the information to be updated is correct, upgrading the firmware of the storage device according to the information to be updated;
step S534, the storage device is switched from the debug mode to the normal mode.
In an embodiment of the present invention, when the steps S531, S532, S533 and S534 are executed, specifically, after the information to be updated is transmitted to the storage device 200, the version number of the information to be updated needs to be compared with the firmware version number of the storage device 200. For example, the version number of the operating system information and/or the firmware information is compared with the version number of the operating system and/or the firmware of the storage device 200. When the version number of the operating system information to be updated is incorrect or the version number of the firmware information to be updated is incorrect, at this time, the storage device 200 may send a version error instruction to the micro control unit 110 of the upgrade device 100 to indicate that the version of the operating system information to be updated or the firmware information to be updated sent by the micro control unit 110 is too low and needs to be downloaded again. The firmware of the storage apparatus 200 can be updated by the information to be updated only when the version number of the operating system information to be updated and the version number of the firmware information to be updated are correct at the same time. After the update is complete, the storage device 200 may be switched from the debug mode to the normal mode.
It can be seen that, in the above solution, for the firmware upgrading process in the storage device, when the storage device is in the normal mode, the firmware of the storage device can be directly upgraded through the host. When the storage device is in a debugging mode, the operating system or the firmware of the storage device cannot run, the host cannot communicate with the storage device, and at the moment, the firmware of the storage device can be upgraded through the upgrading device, so that the storage device can restore normal work. Meanwhile, due to the arrangement of the upgrading device, the storage device does not need to be disassembled and maintained, the integrity of the internal structure of the storage device is guaranteed, and the internal structure of the storage device cannot be damaged.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by functions and internal logic of the process, and should not limit the implementation process of the embodiments of the present invention in any way.
