The following describes a firmware upgrade method for an SSD device according to an embodiment.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for upgrading firmware of an SSD device according to an embodiment of the present disclosure.
In this embodiment, the apparatus may include:
s101, storing the received firmware data to Nand Flash;
it can be seen that this step is intended to save the received firmware data in Nand Flash.
The Nand Flash is one of Flash memories, and a nonlinear macro-unit mode is adopted in the Nand Flash, so that a cheap and effective solution is provided for realizing a solid-state large-capacity memory. The Nand flash memory has the advantages of large capacity, high rewriting speed and the like, and is suitable for storing a large amount of data. Moreover, the data is stored to the Nand Flash speed in the firmware data flashing process, and the Nand Flash is fast, so that the firmware data flashing efficiency can be improved.
Therefore, in the step, the received firmware data is selected to be stored in Nand Flash. The firmware data may be the firmware data acquired from the host side, or may be the firmware data acquired from the preset path, which is not specifically limited herein.
Further, the method can comprise the following steps:
step 1, acquiring firmware data from a host;
and 2, storing the firmware data to Nand Flash.
It can be seen that the present alternative is mainly described how to save firmware data to Nand Flash. In this alternative, firmware data is obtained from the host; then, the firmware data is saved to Nand Flash. Therefore, the alternative scheme is mainly to obtain the firmware data through the host and maintain the reliability of the firmware data.
Further, both Nand Flash and Nor Flash in this embodiment are provided with firmware information spaces;
accordingly, the step may include:
and storing the received firmware data to a firmware information space of Nand Flash.
As can be seen, this step is intended to illustrate how the firmware data is saved. Both Nand Flash and Nor Flash in the embodiment can set a space special for storing firmware data, namely a firmware information space, so that the safety of firmware data storage is improved, and malicious modification of the firmware data is avoided.
S102, when the firmware data is stored, sending an upgrade completion message to the host;
on the basis of S101, this step is intended to send an upgrade completion message to the host when the firmware data saving is completed. That is, when the firmware upgrade of the firmware data is completed, an upgrade completion message is sent to the host computer to inform the host computer that the firmware upgrade operation is completed at this time, so as to perform the subsequent operation.
S103, when the upgrade completion message is sent, the firmware data is synchronized from Nand Flash to Nor Flash.
On the basis of S102, this step is intended to synchronize the firmware data from Nand Flash to Nor Flash when the upgrade complete message is sent. On the basis of firmware upgrading based on Nand Flash, the firmware data is backed up to Nor Flash, so that the storage data stability of Nor Flash is utilized, and the reliability and stability of firmware information storage are improved.
Further, this embodiment may further include:
step 1, judging whether Nand Flash has new firmware data or not when a power-on operation is executed;
step 2, if yes, starting from Nand Flash;
and 3, if not, starting from the Nor Flash.
It can be seen that the present alternative is mainly illustrative of how the start-up may be performed. In the alternative scheme, when the power-on operation is executed, whether the Nand Flash has new firmware data or not is judged; if yes, starting from Nand Flash; if not, starting from Nor Flash. That is, when the firmware data is modified, the boot is performed by Nand Flash, and the boot is performed by Nor Flash without modification. The efficiency of firmware modification is maintained, and meanwhile, the stability degree of firmware data is improved.
Further, step 2 in the last alternative may include:
step 1, copying firmware data in Nand Flash to a starting area;
and 2, booting the system from the boot area, and synchronizing the firmware data from Nand Flash to Nor Flash.
It can be seen that this alternative is mainly to explain how to boot from Nand Flash. In the alternative, the firmware data in the Nand Flash is copied to the boot area, the system is booted from the boot area, and the firmware data is synchronized from the Nand Flash to the Nor Flash.
Further, step 3 in the last alternative may include:
step 1, copying firmware data in Nor Flash to a starting area;
and 2, booting the system from the boot area.
It can be seen that this alternative is primarily illustrative of how boot from Nor Flash can be performed. In the alternative scheme, firmware data in Nor Flash is copied to a boot area; booting the system from the boot area.
Further, this embodiment may further include:
and when the synchronization of the firmware data is completed, setting the storage medium corresponding to the boot sector as Nor Flash.
It can be seen that the present alternative solution mainly illustrates that when the synchronization of the firmware data is completed, the storage medium corresponding to the boot sector is set to Nor Flash. Namely calling Nor Flash to start the system.
In summary, in the embodiment, the received firmware data is upgraded into the Nand Flash, the upgrade operation is completed, the firmware data is synchronized from the Nand Flash to the Nor Flash in the background, that is, the firmware upgrade operation is implemented in the Nand Flash, the upgrade efficiency is improved, the firmware data is synchronously backed up in the Nor Flash, and the device can be started from the Nor Flash or the Nand Flash when being started in the later period, so that the duration of storing the firmware data is prolonged, the reliability and the stability of storing the firmware data are improved, the persistence of storing the firmware data is improved while the upgrade efficiency is improved, and the experience of upgrading the firmware is improved.
Another embodiment is provided below to further explain a firmware upgrade method for an SSD device provided in this application.
In this embodiment, the method may include:
step 1, respectively dividing a space on Nand Flash and Nor Flash for storing firmware data. The Nand Flash can be regarded as the Nor Flash cache.
And 2, when the firmware is upgraded at the host side, the controller side firstly stores the upgraded firmware issued by the host to Nand Flash, and the upgraded firmware can be returned to the host after the upgraded firmware is stored, so that the process can be completed within ms time level, the time consumed for storing the firmware sensed by the host side is shortened, and the upgrading speed is also increased.
And step 3, after the completion message is returned to the host, immediately triggering data to carry out synchronous operation on the Nor Flash, wherein the operation is carried out on the background of the controller, and the host side does not sense the operation and does not obviously influence the service in the disk.
Step 4, if the synchronization is not completed due to the power failure in the data synchronization process, judging that the firmware to be synchronized is updated in the Nand Flash when the Nand Flash is powered on next time, directly copying the firmware in the Nand Flash to a starting area to guide the system to start, and continuing the unfinished synchronization process after the system is started; and if the situation that the firmware to be synchronized is not newly upgraded in the Nand Flash is judged in the power-on process, copying the firmware in the Nor Flash to a system boot area for boot and starting according to a normal starting process.
Therefore, in the embodiment, the received firmware data is upgraded into the Nand Flash, the upgrading operation is completed, the firmware data is synchronized from the Nand Flash to the Nor Flash in the background, that is, the firmware upgrading operation is realized in the Nand Flash, the upgrading efficiency is improved, the firmware data is synchronously backed up in the Nor Flash, and the firmware data can be started from the Nor Flash or the Nand Flash when the equipment is started in the later period, so that the duration of storing the firmware data is prolonged, the reliability and the stability of storing the firmware data are improved, the persistence of storing the firmware data is improved while the upgrading efficiency is improved, and the experience of upgrading the firmware is improved.
