【C】使用bdimg将二进制文件整合成单个文件

作者:KevinJen / 发布于2013/3/18/ 779

在嵌入式开发中所有开发接近尾声后u-boot, kernel, ramdisk,fs等文件要一个一个烧入flash芯片中事件很麻烦的事，因此开发了此程序用于将binery files整合，使用时只需改动配置文件即可。


	#include <stdio.h>
	#include <stdlib.h>
	#include <stdint.h>

	#include "parsecfg.h"
	#include "gennerate_file.h"

	#define _DEBUG 0

	#if _DEBUG
	int printcfg()
	{
	 int i = 0;
	 printf("config : file_name: %s, big_endian: %d, file_size: 0x%x\n", \
	 bd_config.file_name, bd_config.big_endian, bd_config.file_size);
	 for (i=0; i<16; i++) {
	 if (bd_mm[i].enable == 1) {
	 printf("name: %s, start addr: 0x%x, end addr: 0x%x\n", \
	 bd_mm[i].name, bd_mm[i].start_addr, bd_mm[i].end_addr);
	 } else {
	 break;
	 }
	 }

	 return 0;
	}
	#endif

	int main(int argc, char** argv)
	{
	 int ret = 0;

	 ret = parsecfg(argc, argv);
	 if (ret < 0) {
	 printf("Parse configrue file error !\n");
	 return ret;
	 }

	#if _DEBUG
	 printcfg();
	#endif

	 ret = gennerate_file();
	 if (ret < 0) {
	 printf("Generate file error !\n");
	 return ret;
	 }

	 printf("Gennerate \"%s\" succeefully !\n", bd_config.file_name);
	 return ret;
	}

	 goto out;
	 }

	 fread(filepb + bd_mm[i].start_addr, 1, file_size, cb);

	 fclose(cb);

	 ret = -3;

	 fwrite(filepb, file_size, 1, gf);

	out:
