Detailed Description
In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, an implementation flowchart of a method for upgrading firmware of an expansion chip provided in an embodiment of the present application is shown, where the method may include the following steps:
s110: when the firmware of the target expansion chip is to be upgraded, the type identification field of the expansion chip in the EEPROM of the chassis backboard is read.
In the operation process of the storage system, firmware upgrading can be carried out on an expansion chip, namely an expander, on the board card according to actual needs. The firmware upgrade trigger condition may be preset, for example, when the set time interval is reached, the firmware upgrade trigger condition is considered to be reached, or when the firmware upgrade instruction is received, the firmware upgrade trigger condition is considered to be reached. When the firmware upgrading triggering condition is reached, the firmware upgrading operation on the target expansion chip can be triggered.
When the firmware of the target expansion chip is to be upgraded, the expansion chip type identification field in an EEPROM (Electrically Erasable Programmable Read Only Memory) of the chassis backplane may be Read.
Specifically, the extended chip type identifier field in the EEPROM of the chassis backplane may be read through an SES (SCSI Enclosure Service) protocol (a protocol for performing chassis management in an SAS protocol) or an IIC (Inter-Integrated Circuit) protocol. For example, an open-source sg _ util tool is used for reading the extended chip type identification field in the EEPROM based on the SES protocol, or an IIC read-write tool is used for reading the extended chip type identification field in the EEPROM based on the IIC protocol.
In a specific embodiment of the present application, the extended chip type identifier field is burned into the EEPROM in a bin file manner before the board leaves the factory.
The bin file may be obtained by:
the method comprises the following steps: defining the length, offset and content of an extended chip type identification field in the EEPROM in a table, and storing the length, offset and content in a csv format;
step two: the table is output to the bin file.
In the embodiment of the invention, different extended chip type identification fields can be defined for hardware platforms on which different extended chips are mounted, and the fields are used for unique identification of the extended chips. The length, offset and content of the extended chip type identifier field in the EEPROM may be defined in a table, such as EXCEL, and saved in csv format, and then the table may be output to the bin file, such as in 16-ary format, by a pre-programmed script. And then the extended chip type identification field is burned into the EEPROM in a bin file mode before the board is delivered from a factory. This way of generating the bin file is simple and efficient.

After the type of the target expansion chip is determined, a desired firmware version corresponding to the type of the target expansion chip can be further determined.
In practical application, a mapping table of the extended chip type and the firmware version may be pre-established, and a desired firmware version corresponding to the type of the target extended chip may be determined through the pre-established mapping table of the extended chip type and the firmware version. The expected firmware version corresponding to the type of the target extension chip can be conveniently determined through the mapping table.
