LiteOS系统--快速烧写.bin文件到norflash相应位置

华为LiteOS系统因OS和app代码是通过接口app_init衔接在一块的，所以在开发调试中每次进行修改后都需要重新烧写flash，这样其实很麻烦，所以干脆写了个工具辅助进行文件传输，使用TCP协议，代码分为设备端和linux主机端，

注意在LiteOS系统调用的app_init（）函数里边，注册如下命令：

osCmdReg(CMD_TYPE_EX, "WriteNorFlash",1, (CMD_CBK_FUNC)write_file_to_nor_flash); osCmdReg(CMD_TYPE_EX, "RecvWriteNor",0, (CMD_CBK_FUNC)receive_and_write_file_to_nor_flash);

 

用来在命令行下通过输入命令“WriteNorFlash” 或者“RecvWriteNor”直接调用如下函数写入或接收写入.bin文件到指定Norflash位置：

设备端代码 .c  和 .h文件：

 其中擦写的起始地址和大小可通过宏来改变：

#define FLASH_START_ADDRESS 0x100000   //liteOS写OS和app的起始地址 #define ERRASE_SIZE   (7*1024*1024)           //擦除7M大小的空间

这里就举例其中一个命令“RecvWriteNor”的使用：

设备端先输入命令进入监听模式：

之后linux端运行： ./send_and_write_file_to_norflash ipc18.bin 192.XXX.XXX.XXX

设备端将自动接收文件并写入到Norflash对应地址处（注意 IP得在同一网段且互相能ping通）。

success！
