s2, comparing the firmware to be refreshed with the N sectors of the current firmware one by one, finding out sectors with different information, and recording the sectors as sectors to be refreshed;
and S3, performing flash on the sector to be flashed.
Firstly, dividing the firmware to be refreshed and the current firmware into sectors which are divided in the same mode, wherein the number of the sectors is the same, then comparing the firmware information by taking the sectors as a unit, comparing the first sector of the firmware to be refreshed with the first sector of the current firmware, and so on, finding out the sectors with inconsistent information, indicating that the information in the sectors is changed and needs to be refreshed, and finally, refreshing the sectors to be refreshed, namely refreshing the information in the sectors to be refreshed in the firmware to be refreshed in the sectors to be refreshed corresponding to the sectors to be refreshed.
Before the sectors are divided into the firmware, the firmware to be refreshed and the current firmware are converted into hexadecimal code information, and the sectors are divided into N sectors based on the hexadecimal code information so as to facilitate information comparison.
According to the method for refreshing the firmware of the server, provided by the embodiment of the invention, by utilizing the characteristic that the time for reading the code information is much faster than the time for writing, the difference point between the firmware information to be refreshed and the existing firmware information in a Flash chip is obtained by comparing the firmware information to be refreshed and the existing firmware information in the Flash chip, and then only the difference part is written, so that the repeated writing of the same code part is avoided, the time of an FW (firmware) flashing process is effectively reduced, and the FW flashing efficiency is improved.
Fig. 2 is a flowchart illustrating a method for refreshing server firmware according to an embodiment of the present invention, as shown in fig. 2, the method includes the following steps.
S1, respectively dividing the firmware to be refreshed and the current firmware into N sectors in the same mode.
And S2, dividing each sector of the firmware to be refreshed into M pages respectively according to the same mode, and dividing each sector of the current firmware into M pages respectively.
And S3, comparing the firmware to be refreshed with the N sectors of the current firmware one by one, finding out sectors with different information, and recording the sectors as sectors to be refreshed.
And S4, comparing the M pages of the sector to be refreshed one by one, finding out pages with different information, and recording as the pages to be refreshed.
And S5, performing flash on the page to be flashed.
In the embodiment, the efficiency is higher when the flash is performed in the unit of page than when the flash is performed in the unit of sector. The sector with updated information is found out firstly, a plurality of pages are arranged in the current sector, the information of each page is not updated, then the page with updated information is found out and recorded as the page to be refreshed, and only the page to be refreshed is refreshed, so that the updating of the firmware can be ensured, and the updating efficiency is improved.

S1, respectively dividing the firmware to be refreshed and the current firmware into N sectors in the same mode.
And S2, dividing each sector of the firmware to be refreshed into M pages respectively according to the same mode, and dividing each sector of the current firmware into M pages respectively.
S3, comparing the firmware to be refreshed with the N sectors of the current firmware one by one, finding out sectors with different information, and recording as sectors to be refreshed.
And S4, comparing the M pages of the sector to be refreshed one by one, finding out pages with different information, and recording as the pages to be refreshed.
And S5, judging whether the page to be refreshed of the current firmware is empty or not.
And S6, if the firmware is empty, directly flashing the information of the page to be flashed corresponding to the firmware to be refreshed to the page to be flashed of the current firmware.
And S7, if the firmware is not empty, erasing the page to be refreshed of the current firmware, and after the erasing is successful, refreshing the information of the page to be refreshed of the firmware to be refreshed to the page to be refreshed of the current firmware.
Before the flash is performed, the page to be flashed in the current firmware needs to be erased, in order to improve the flash efficiency, in this embodiment, before the flash is erased, it is determined whether the page to be flashed in the current firmware is empty, and if the page is empty, the flash does not need to be erased, so that the erasing step is omitted, and the flash can be performed directly. And in the case of not being empty, erasing is performed first and then writing is performed.
The step S7 specifically includes the following steps.
S7-1, erasing the page to be flashed of the current firmware;

After the page to be refreshed of the current firmware is subjected to one-time erasing operation, whether the page to be refreshed of the current firmware is erased completely or not is detected, and the refreshing and erasing are performed under the condition of complete erasing so as to ensure normal refreshing and writing. If not, erasing is performed again. Certainly, if the memory chip cannot be erased for a plurality of times and then erased for a certain number of times and still cannot be erased completely, the memory chip possibly fails, and at the moment, an abnormal alarm of the memory chip is sent out to inform a worker to process the memory chip in time.
Before the sectors are divided into the firmware, the firmware to be refreshed and the current firmware are converted into hexadecimal code information, the sectors are divided into N sectors based on the hexadecimal code information, and then each sector is divided into a plurality of pages based on the hexadecimal code information, so that information comparison is facilitated.
Correspondingly, whether the page to be written with a brush is empty or whether the page to be written with a brush is erased completely is specifically as follows: and judging whether the hexadecimal code information of the page to be refreshed is totally FF, if so, the page to be refreshed is empty or erased completely.
According to the method for refreshing the firmware of the server, provided by the embodiment of the invention, by utilizing the characteristic that the time for reading the code information is much faster than the time for writing, the difference point between the firmware information to be refreshed and the existing firmware information in a Flash chip is obtained by comparing the firmware information to be refreshed and the existing firmware information in the Flash chip, and then only the difference part is written, so that the repeated writing of the same code part is avoided, the time of an FW (firmware) flashing process is effectively reduced, and the FW flashing efficiency is improved.
To further understand the present invention, a specific embodiment is provided below to further explain the present invention in detail, and fig. 4 is a schematic flow chart of the method of the specific embodiment.
The specific embodiment utilizes the characteristic that the time for reading code information is much faster than the time for writing code information, obtains the difference point between Flash FW information to be refreshed and Flash Existing FW by comparing the Flash FW information (Update FW) of firmware to be refreshed and Flash Existing FW information (Existing FW), and then writes only the difference part as follows.

3. And comparing each Update Sector with an Existing Sector, if the Update Sector N is the same as the Existing Sector N, the FW information to be refreshed is the same as the FW information in Flash, the Flash does not need to be refreshed and written, and if the Update Sector N is different from the Existing Sector N, the step 4 is carried out.
4. For different SectorN, comparing the Update Page M with the Existing Page M for each Page of the SectorN, keeping the same Page part for the same Page without operation, and performing the step 5 for different pages.
5. Judging whether FW information of different Existing Page M hexadecimal codes is totally FF, if yes, representing that no FW information exists in Flash, and directly performing Flash without erasing; if the Existing PageM hexadecimal codes are not all FFs, go to step 6.
