Problems solved by technology

[0004] However, the above method code is implemented internally, and no external channel is opened to users, which makes it difficult for users to maintain, and the parameter configuration is solidified, resulting in a single firmware function, which is not compatible with NAND that may be supported in the future.

Abstract

The invention discloses a SPI-NAND configuration-file obtaining method and device. The SPI-NAND configuration-file obtaining method includes the steps that firmware burn instructions are received, wherein the firmware burn instructions are used for triggering to carry out initial burn for SPI-NAND firmware; according to the firmware burn instructions, pre-generated configuration files are called,wherein the configuration files are used for providing values of configuration parameters involved in the initial burn process; the configuration files are stored into reserved areas in SPI-NAND so that the values of the configuration parameters can be extracted from the reserved areas. According to the SPI-NAND configuration-file obtaining method and device, a path when the configuration parameters are modified according to the actual situation is provided for a user, user maintaining is convenient, expanding space is reserved in the configuration files, the configuration files can meet the more requirements, and a basis is provided for the diversified firmware function.

Description

technical field [0001] The embodiment of the present invention relates to SPI-NAND technology, and in particular to a method and device for obtaining a configuration file of SPI-NAND. Background technique [0002] Serial Peripheral Interface (abbreviation: SPI) NAND firmware (Firmware) is inseparable from the index, checksum and use of key configuration parameters during initial programming and power-on operation. The setting method is related to the efficiency of firmware operation and the convenience of user maintenance after release. [0003] Usually, the indexing, verification and use of key configuration parameters are realized by fixed codes, that is, the firmware initialization program Initial.c of SPI-NAND is written, which realizes the setting of key configuration parameters required for firmware power-on initialization and runtime, The index of the required parameter and the configuration of the corresponding register. [0004] However, the above-mentioned method...
