Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but 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.
Example 1
Referring to fig. 1, a flowchart of a firmware update operation method of a BMC according to an embodiment of the present application is shown. According to the embodiment, the BMC firmware is quickly updated and started through the starting mark, so that the updating stability of the BMC firmware and the user experience are improved. The firmware updating operation method of the BMC comprises steps 101 to 105, wherein the steps are specifically as follows:
step 101: dividing a storage interval of the BMC firmware storage medium; when detecting a new firmware of a non-current version, responding to a user update operation instruction; the user updating operation instruction is determined according to BMC firmware updating requirements; the BMC firmware update requirement includes one of selecting the latest version of BMC firmware, selecting a history of a version of BMC firmware, and selecting a particular version of BMC firmware.
It should be noted that, baseboard Management Controller (BMC), a baseboard management controller, is used to manage hardware on a server, and can perform a series of operations such as firmware upgrade and checking of a machine device when the machine is not powered on, and also provides a function of remotely managing hardware of the server. The main function of Firmware (Firmware) is to provide the lowest, most direct hardware setup and control for the computer, and in addition, the Firmware is responsible for initializing some necessary hardware, and at the same time providing some system parameters to the operating system, guiding the operating system to boot up.
Optionally, step 101 specifically includes steps 1011 to 1012, each of which specifically includes the following steps:
step 1011: judging whether the number of BMC firmware storage media is 1 or not; if not, correspondingly dividing different storage media into different storage sections; if yes, the current storage medium is divided into a third storage interval, a fourth storage interval and a fifth storage interval according to the size of the BMC firmware and the storage space of the current storage medium.
In this embodiment, the storage medium of the BMC firmware is generally Flash, and if there are multiple storage media in the BMC firmware, each storage medium is a storage interval, for example: if the BMC firmware only has 1 storage medium, the storage medium is divided according to the size of the firmware and the storage space of the storage medium, three sections are divided in the storage medium of the BMC firmware, two sections A (third storage section) and B (fourth storage section) are used for storing the firmware, and the other section C (fifth storage section) stores other information such as a start-up flag.
As an example of this embodiment, when the number of BMC firmware storage media is only 1, assuming that the size of the BMC firmware is size, the storage space of Flash is at least 2×size+16,0 to (size-1) is area a, size to (2×size-1) is area B, the remaining 16 bytes are area C, and the area C stores other information such as a start flag. In the process of updating the firmware, the initial state is assumed, the firmware operated by the BMC is stored in the A section, when the firmware needs to be updated, the firmware is updated to the B section instead of directly covering the A section, so that the old firmware of the A section is not damaged when the updating fails, when the updating succeeds, a starting mark is set to the B section, so that the new firmware of the B section is operated when the restarting is performed, when the updating fails, such as failure caused by power failure, the starting mark is still the A section, and the firmware of the A section is still operated when the restarting is performed.
Step 1012: when detecting a new firmware of a non-current version, responding to a user update operation instruction; the user updating operation instruction is determined according to BMC firmware updating requirements; the BMC firmware update requirement includes one of selecting the latest version of BMC firmware, selecting a history of a version of BMC firmware, and selecting a particular version of BMC firmware.

Step 102: the method comprises the steps of reading a current starting mark of the BMC in a server, and determining a current running storage interval according to the current starting mark to obtain a first storage interval.
In this embodiment, as shown in fig. 2, the simplified flow of firmware update is that the stored start flag is read to determine which storage interval to start from currently, i.e. start from zone a or from zone B, so as to store new firmware into another storage interval without covering the currently started storage interval when updating firmware later.
Step 103: updating and receiving new firmware through a preset receiving mode, and storing the new firmware into a second storage interval;

In the embodiment, in the updating process, the integrity and the correctness (such as hash check, cyclic redundancy check and the like) of the BMC firmware are checked, and if the verification is passed, the success of the updating is indicated, and then the storage interval of the new firmware to which the start mark is stored is updated; if the verification is not passed, the start flag is not updated. In particular, when the process of receiving the new firmware fails (such as power failure, network interruption, flash controller failure, ethernet failure, etc. in the process of updating), the start-up flag is not updated.
