Detailed Description
In order to clearly illustrate the technical features of the present solution, the present invention will be described in detail below with reference to the following detailed description and the accompanying drawings. The following disclosure provides many different embodiments, or examples, for implementing different structures of the invention. In order to simplify the present disclosure, components and arrangements of specific examples are described below. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. It should be noted that the components illustrated in the figures are not necessarily drawn to scale. Descriptions of well-known components and processing techniques and processes are omitted so as to not unnecessarily obscure the present invention.
As shown in fig. 1, an embodiment of the present invention provides a firmware storage method, which includes the following steps:
s1, programming factory firmware to a preset slot stored in a hard disk nandflash, wherein the slot is divided into two parts of a table tennis;
s2, when a preset timing strategy is met in the running process of the firmware, the firmware is moved to another part based on the part of the current storage position of the firmware.
As shown in fig. 2, in step S2, a plurality of slots are set, each slot is divided into two parts of ping pong, and each part is divided into two parts of primary and secondary parts.
When the SSD is in industrialization, the factory firmware is programmed into the nandflash of the SSD, in order to prevent the subsequent firmware from being updated online to damage the factory firmware, the slot1 is set to be read-only, and the position of the slot2 or the slot3 can be updated online. Slot is respectively positioned on different die (memory chips) of the same block of nandflash.
When the firmware is written or updated online, the same slot can be written with two copies on the nandflash, the two copies are used as backups, when the SSD is electrified, a bootstrap program can firstly read from the slot main firmware position, if the read is successful, the firmware is loaded, and if the read fails, the same slot backup position is read.
Different channels in the same block are used as backups for slot firmware.
In step S2, the specific process of moving the firmware to another part based on the part to which the current storage location of the firmware belongs is as follows:
judging whether the nandflash of the other part is erased or not;
if not, executing an erasing operation, and then writing the firmware into the other part;
if yes, the firmware is directly written into the other part.
And when the firmware is written into the other part, the main part and the standby part are simultaneously written.
When the firmware moving operation is carried out, each slot in which the firmware is stored is moved under the current slot, and if the operation fails, the risk of losing the firmware is reported.
In one implementation manner of the embodiment of the present invention, after the firmware is moved to another part, the method further includes:
the pointer of the current firmware in the metadata is changed to point to the other part. When the SSD is powered up again, the firmware is read from the pointer location in the metadata.
As shown in fig. 3, the firmware storage system provided in the embodiment of the present invention includes a firmware writing unit 1 and a firmware moving unit 2.
The firmware programming unit 1 is used for programming factory firmware to a preset slot stored in the nandflash, and the slot is divided into two parts of table tennis; the firmware moving unit 2 is used for moving the firmware to another part based on the part of the current storage position of the firmware when the preset timing strategy is met in the firmware operation process.
The system further comprises a configuration unit 3, wherein the configuration unit 3 is used for setting a plurality of slots on the nandflash, each slot is divided into two parts of ping pong, and each part is divided into two parts of main part and standby part.
When the SSD is in industrialization, the factory firmware is programmed into the nandflash of the SSD, in order to prevent the subsequent firmware from being updated online to damage the factory firmware, the slot1 is set to be read-only, and the position of the slot2 or the slot3 can be updated online. Slot is respectively positioned on different die (memory chips) of the same block of nandflash.
When the firmware is written or updated online, the same slot can be written with two copies on the nandflash, the two copies are used as backups, when the SSD is electrified, a bootstrap program can firstly read from the slot main firmware position, if the read is successful, the firmware is loaded, and if the read fails, the same slot backup position is read.
When the firmware runs, for example, the timer is 10 days, when the timer expires, the firmware firstly judges which part of ping pong is the current position, if so, the firmware judges whether nandflash of the pong position is erased, if not, the firmware is written into the pong position, the pointer of the current firmware in the metadata is changed, and when the SSD is powered on again, the firmware is read from the pointer position in the metadata.
The firmware moving operation traverses each slot, if the slot has firmware, the step (3) is carried out; if the recovery operation fails, an alarm needs to be reported, and the firmware of the SSD is at risk of being lost.
The embodiment of the invention also provides a computer storage medium, wherein computer instructions are stored in the computer storage medium, and when the computer instructions run on a system, the system is caused to execute the steps of the method.
While the foregoing description of the embodiments of the present invention has been presented in conjunction with the drawings, it should be understood that it is not intended to limit the scope of the invention, but rather, it is intended to cover all modifications or variations within the scope of the invention as defined by the claims of the present invention.
