Multi-particle adaptive initialization method, device, computer device and storage medium

Abstract

The invention relates to a multi-particle adaptive initialization method, a device, a computer device and a storage medium. The method comprises the steps of setting a main control mode as an asynchronous mode; adopting an asynchronous mode to initialize particles; getting the particle ID; switching the particle mode according to the particle ID. By setting the main control mode as an asynchronousmode, initializing the particles in the mode, and keeping the frequency of the master NAND flash memory in the synchronous mode and the master operation to be less than 20MHz, it is ensured that regardless of the particle in which mode, the asynchronous mode is used for initialization, the same set of code and different batches of products compatible with different particles or the same particleare used to achieve SSD multi-particle adaptive, which does not need to modify the firmware configuration, and enables strong compatibility.

Description

technical field [0001] The invention relates to a solid-state hard disk, and more specifically refers to a multi-particle self-adaptive initialization method, device, computer equipment and storage medium. Background technique [0002] Solid State Drives (SSD) are generally divided into two parts: main control and NAND Flash particles. Particle interfaces of different manufacturers are divided into Async (that is, asynchronous serial), Toggle (that is, based on dynamic random access memory) flash memory interface), ONFI (Open NAND Flash Memory Interface, Open Nand Flash Interface), etc. Different batches of products from the same manufacturer will have different power-on initialization processes. For example, Micron (that is, American Micron) particles are always in synchronous mode when powered on, while Toshiba (that is, Toshiba) Bics3 particles may be in synchronous mode or switching mode when powered on. [0003] The general steps of power-on and initialization of the ...

Problems solved by technology

The timing of Toshiba particles after power-on is as follows figure 1 As shown, after the master sends the FFh and 70h commands, the particle may be in the synchronous mode or the switching mode

At this time, there is no chance to read the ID of the particle, so the model of the particle cannot be known, and targeted actions cannot be taken. The existing method is to confirm the model of the particle first, and then modify the firmware to adapt to the entire process of reading the ID, resulting in Different batches of SSD products may use different batches of granules, and the different granules will lead to the need to frequently modify the firmware configuration to be compatible with the diversity of granules, causing inconvenience in use
