Firmware loading method and device of solid state disk, computer equipment and storage medium

Abstract

The invention relates to a firmware loading method and device of a solid state disk, computer equipment and a storage medium. The method comprises the following steps: reading full-system management information in a NandFlash to a first address specified by an SRAM; finding the position of a BootLoader program in the NandFlash from the whole system management information, and loading the BootLoader program to a second address specified by the SRAM; the method also includes that the BootRom program jumps to a second address appointed by the SRAM, and the BootLoader program is operated; the BootLoader program finds a storage position of a system data full-system firmware program in the NandFlash from the full-system management information at a first address specified by the SRAM, and loads the full-system firmware program to a third address specified by the SRAM; and the BootLoader program skips to a third address specified by the SRAM, and the whole system firmware program is operated. According to the invention, the risk that the SSD becomes a waste disk due to the failure of loading the BootLoader is avoided.

Description

Technical field [0001] The present invention relates to the technical field of solid state drives, and in particular, a firmware loading method, apparatus, computer device, and storage medium relating to a solid state hard disk. Background technique [0002] Computer equipment has become the most produced utility of today's people. With the decline of solid state drives, solid state drives are getting more popular, NVME SSD referred to as SSD (Solid State Disk or Solid State Drive) is developed with its superior performance. It is rapidly, and major computer vendors have made the hard drive in the computer equipment SSD. [0003] Currently, the SSD firmware load process is implemented in the traditional technology to: SSD power-on running bootrom programs, Bootrom reads the BootLoader program from the NANDFLASH fixed Block / Page address, run the bootloader program, and then load the full system firmware after running. Implement the loading of all system firmware. During the abov...

AI Technical Summary

Problems solved by technology

In the above implementation process, the fixed block / page of BootLoader stored in NandFlash is required to have good stability. In addition, the BootRom program is solidified in ROM and cannot be changed. Once the failure to read BootLoader is easy to cause SSD failure due to failure to load firmware Become a waste disk

At the same time, because the blocks with better stability of NandFlash particles of different protocols and different models are generally not uniform, this requires SSD manufacturers to try to choose blocks with better stability for different particles to store the BootLoader program to ensure that BootRom never The BootLoader program can be read correctly in these fixed blocks, that is, the BootRom program of the current SSD has poor compatibility with NandFlash particles
