Abstract

The invention discloses an NAND reset method and a device, electronic equipment and a storage medium. The NAND reset method comprises the steps that when initialization of an NAND controller is completed, sending a reset instruction to an NAND after preset time is delayed; obtaining an NAND state fed back by the NAND; and if the NAND is judged to be in the standby state according to the NAND state, judging whether the NAND is successfully reset or not according to the NAND ID. According to the method, the problem of misjudgment of the NAND reset operation is solved, and the stability and accuracy of the NAND reset operation in the power-on initialization stage of the NAND storage device are improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of storage technologies, and in particular, relate to a NAND reset method, device, electronic equipment, and storage medium. Background technique [0002] During the power-on process of the NAND storage device based on the SPI protocol or the eMMC protocol, after the NAND controller is powered on, the NAND storage device needs to be powered on and initialized. In order to ensure the correctness of the NAND operation by the firmware, the NAND must be reset to eliminate the abnormal state of the NAND. [0003] In the power-on initialization stage of the NAND storage device, the initialization of the NAND controller is first completed, and then a reset command is sent to the NAND, and the NAND status returned by the NAND is read. According to the NAND status, it can be judged whether the NAND reset operation is successful. However, at the initial stage of power-on of the NAND storage device, the NA...
