At present, the SSD firmware is usually divided into two parts: Boot Loader (BL) and User Firmware (FW) for storage and loading. The SSD needs to ensure that the loaded BL and FW belong to the same version, so the version update usually chooses to update only the FW. In the case where the BL and FW are updated together, this firmware storage and loading scheme cannot guarantee that the loaded BL and FW belong to the same version, which may lead to the problem of inconsistent firmware versions.

Based on this, the present invention proposes a method for consistent loading of SSD firmware, which aims to ensure the boot security of SSD firmware even when BL and FW are updated together.

Step 102, obtaining the SSD firmware consistency loading request;

Step 104, merge and store the Bootloader and Firmware of the firmware and update them together according to the SSD firmware consistency loading request;

Step 106, checking the consistency of the firmware by comparing the write timestamps of the SSD firmware backup;

Step 108, if the writing time stamps are inconsistent, then reload the Bootloader and load the boot firmware from the corresponding firmware backup of the Bootloader;

Step 110, if the writing time stamps are consistent, the boot firmware is directly loaded from multiple copies of firmware in parallel.

In this embodiment, a method for protecting the loading consistency of SSD firmware is proposed. The method combines BL and FW for storage. In the case where BL is allowed to be updated, the firmware consistency check can also ensure the boot security of SSD firmware. The specific implementation steps are as follows:

BL and FW.

The BL and FW of the SSD firmware are backed up and updated together. Next, the firmware consistency check compares the write timestamps of the SSD firmware backup. If the timestamps are inconsistent, the BL is reloaded and the boot firmware is loaded from the firmware backup corresponding to the BL. If the time stamps are the same, skip the BL reloading and directly load the boot firmware from multiple firmware copies in parallel.

In this embodiment, by obtaining the SSD firmware consistency loading request; according to the SSD firmware consistency loading request, the Bootloader and Firmware of the firmware are combined and stored and updated together; Consistency; if the writing time stamps are inconsistent, the Bootloader is reloaded and the booting firmware is loaded from the corresponding firmware backup of the Bootloader; if the writing time stamps are consistent, the booting firmware is directly loaded from multiple copies of firmware in parallel. In this solution, the Bootloader and Firmware are combined and stored. In the case of allowing the Bootloader to be updated, the firmware consistency check can also be used to ensure the boot safety of the SSD firmware.

In one embodiment, as shown in FIG. 2, a method for consistent loading of SSD firmware is provided, and the method further includes:

Step 202, after the SSD is powered on, read the last write positions of all firmware backups in parallel, and obtain and compare the write timestamps of the firmware backups;

Step 204, if the writing time stamps are consistent, skip the process of reloading the Bootloader, and directly load the boot firmware from multiple copies of firmware in parallel;

Step 206, if the writing time stamps are inconsistent, start from the first backup to search for a backup with both Bootloader and Firmware intact;

Step 208 , if a complete backup cannot be obtained after searching for all the backups, the firmware startup fails; otherwise, the Bootloader and the Firmware are sequentially loaded from the obtained backups.

In this embodiment, referring to the schematic diagram of the consistency check flow of the SSD firmware backup shown in FIG. 4 , it specifically includes: after the SSD is powered on, reading the last write positions of all firmware backups in parallel, obtaining and comparing the firmware backups and writing Timestamps. If the timestamps are inconsistent, reload the BL and load the boot firmware from the corresponding firmware backup of the BL. If the timestamps are consistent, choose to load the boot firmware from multiple copies of firmware in parallel.

Refer to the schematic diagram of the loading process when the SSD firmware backups are inconsistent as shown in Figure 5, which includes: loading the SSD firmware, starting from the first backup to search for a backup with both BL and FW intact. The firmware fails to start; otherwise, BL and FW are loaded in sequence from the obtained backup.
