Problems solved by technology

[0003] The current SSD system initialization method for Nand particles is to make corresponding settings for the particles and complete the adaptation of Nand controller and interface physical layer parameters during the initialization process according to the protocol followed by the particles and the default working mode before the SSD system code is compiled. , for Nand particles with different protocols and different default working modes, the initialization process must be adapted accordingly before the code is compiled, which is inefficient

Abstract

The invention relates to a method and device compatible with Nand particles of different protocols, computer equipment and a storage medium. The method comprises the steps that a Nand controller is initialized, and a reset command is sent to particles; the Nand controller circularly sends a particle state query command until it is queried that the particles are in an idle state; the Nand controller sends an ONFI protocol to read a particle ID command and receives ID information 1 fed back by the particles; a judgment is made as to whether an ID item of a particle information table which is stored in an SSD and supports an ONFI protocol contains feedback ID information 1 or not; and if the ID information 1 fed back is not included, the Nand controller sends a Togle protocol to read the particle ID command and receives the ID information 2 fed back by the particles. The inventioncan be compatible with Nand particles with different interface protocols and different default working modes to complete the initialization process, so that the firmware release process is simplified, and the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of solid-state hard disks, and more specifically refers to a method, a device, a computer device and a storage medium compatible with Nand particles of different protocols. Background technique [0002] At present, the Nand particle interface mainly follows the two interface protocols of ONFI and Toggle. For the Nand particle of the ONFI interface, it generally starts in asynchronous mode, and the Nand particle of the Toggle interface generally starts in the default mode, that is, the asynchronous mode, but there are also particles of the Toggle interface. The default working mode is Toggle mode. [0003] The current SSD system initialization method for Nand particles is to make corresponding settings for the particles and complete the adaptation of Nand controller and interface physical layer parameters during the initialization process according to the protocol followed by the particles and the default wor...
