* 一、功能: Fine-gained Flash Access驱动演示代码. * 二、运行前提: 本范例需要硬件开发板的支持, * 要求硬件开发板具备名为”ext_flash”的CFI Flash或EPCS Flash模块

完全支持CFI协议的Flash驱动，支持多种Flash芯片，换Flash不用修改代码,Fully supports the CFI' s Flash-driven protocol to support a wide range of Flash chips, do not modify the code for Flash

Flash芯片的CFI驱动c语言源代码,对自升级的系统有帮助。-Flash chips CFI driver c language source code, since the upgrade of the system has to help.
