Template:ROM-Maker-lite Introduce
If you have a customized U-boot, Linux kernel and file system and want to use them to make a Linux image file(we call it "ROM" in the following sections) you can use the "dd" command the copy all the data and files in your SD card with a Linux ROM. 、文件系统，并且想基于自己定制的文件制作Linux系统映像文件 (以下简称为ROM文件)，你可以选择用dd命令将带有你的应用程序和配置的SD卡的数据完整地拷贝出来，这种方法简单粗暴，但是效率不高。另外，你也可以使用FriendlyElec 提供的rom-maker-lite工具。
rom-maker-lite是一套通用的制作映像文件的脚本工具，目前支持为 H3/H5 系列的开发板制作Linux平台的sd/eflasher ROM文件(尚未支持Android)。
- 执行./mkimage.sh查看帮助信息:
$ ./mkimage.sh Usage: $ apt-get install tree exfat-utils dosfstools python3-tk $ ./mkimage.sh -c <filesystem type> -m <partmap> -d "<misc dir>;<partition1 dir>;<partition2 dir>;..." -c <filesystem type>: 1: misc(bootloader) + fat32 boot.img + ext4 rootfs.img 2: misc(bootloader) + fat32 boot.img + ext4 rootfs.img + exfat friendlyarm.img 3: misc(bootloader) + ext4 boot.img + ext4 rootfs.img
Parameter Comment -c <filesystem type> -c specifies file systems' formats for the partitions in a ROM Image. Specifically for an H3/H5 based board:
-c 1 stands for "misc(bootloader) + fat32 boot.img + ext4 rootfs.img" and this applies to an sd ROM of FriendlyCore/Ubuntu/Debian/OpenWrt;
-c 2 stands for "misc(bootloader) + fat32 boot.img + ext4 rootfs.img + exfat friendlyarm.img" and this applies to an eflasher ROM.-m <partmap> -m specifies a partmap file for making a ROM.
A partmap file is used to specify the files and their sizes included in a ROM. ROMs made for different boards or BSPs may need different partmap files.-d "<misc dir>;<partition1 dir>;<partition2 dir>;..." -d specifies file system's path and each path is separated by a ";". Specifically for an H3/H5 based board:
<misc dir>: specifies the bootloader's path;
<partition1 dir>: specifies the boot partition's path;
<partition2 dir>: specifies the rootfs partition's path;
"..." means more paths can be defined. When you make an eflasher ROM you need to include the friendlyarm partition's path;
- 准备工作
经测试过PC机 Ubuntu版本包括:
1) ubuntu-16.04.5-desktop-amd64.iso
2) ubuntu-18.04.1-desktop-amd64.iso
如果你当前PC机使用的Ubuntu系统无法成功执行出系统映像，请尝试切换到上面这两个版本的Ubuntu系统。
在开始制作系统映像前，必须先安装下列软件包:
$ apt-get install tree exfat-utils dosfstools python3-tk
由于制作系统映像需要root权限，请先切换到root用户:
$ su root
