/uC-NAND-PC

将uC-FS的NAND驱动移植到PC上仿真,并进行修改为不依赖于其他模块可独立使用的库

Primary LanguageC

介绍

本库来源于https://github.com/weston-embedded/uC-FS.git （uC-FS/Dev/NAND） 将uC-FS的NAND驱动移植到PC上仿真,并进行修改,改为不依赖于其他模块可独立使用的库。

详细原理介绍可以关注公众号 766ad473b1e8d3e19acb90df0243c0e

Linux下使用

Windows下的gcc工具链也一样。

  • 编译 make
  • 创建测试bin文件代表FLASH touch nand.bin
  • 运行测试 ./nand

打印如下:

Windows下使用

使用Visual Studio 2022 双击打开NAND_VS\NAND_VS.sln 选择Debug,X86目标构建,运行。 同样需要先在NAND_VS下创建空白文件nand.bin
