【linux】全志Tina配置swupdate工具进行分区打包

一、文件路径

1、描述文件：

.\build\swupdate\sw-description-ab

2、镜像打包文件：

.\build\swupdate\sw-subimgs-ab.cfg

二、文件作用

1、sw-description-ab

用于描述版本信息和ab区中要打包的分区信息以及挂载点。

2、sw-subimgs-ab.cfg

用于列举编译后存在于out目录下的文件中，要参与swupdate打包时的ab区分区名称信息

三、文件内容

1、sw-description-ab

software =
{version = "0.1.0";description = "Firmware update for Tina Project";stable = {/* now in systemA, we need to upgrade systemB(bootB, rootfsB) */now_A_next_B = {images: (/* {filename = "kernel";volume = "bootB";                },{filename = "rootfs";volume = "rootfsB";                  },*/{filename = "scu_b";device = "/dev/mtdblock17";	   }/*,{filename = "uboot";type = "awuboot";},{filename = "boot0";type = "awboot0";},  {filename = "app";device = "/dev/mtdblock12";	   },    */          );bootenv: ({name = "swu_mode";value = "";},{name = "scuAB";value = "B";}/* {name = "boot_partition";value = "bootB";},{name = "root_partition";value = "rootfsB";},{name = "systemAB_next";value = "B";},{name = "swu_version";		value = "2.0.0";},{name = "swu_next";value = "reboot";}*/);};/* now in systemB, we need to upgrade systemA(bootA, rootfsA) */now_B_next_A = {images: (/*{filename = "kernel";volume = "bootA";},={filename = "rootfs";volume = "rootfsA";},*/{filename = "scu_a";device = "/dev/mtdblock16";	                   }/*,{filename = "uboot";type = "awuboot";},{filename = "boot0";type = "awboot0";},{filename = "app";device = "/dev/mtdblock12";	   },   */);bootenv: ({name = "swu_mode";value = "";},{name = "scuAB";value = "A";}/*{name = "boot_partition";value = "bootA";},{name = "root_partition";value = "rootfsA";},{name = "systemAB_next";value = "A";},{name = "swu_version";		value = "2.0.0";},{name = "swu_next";value = "reboot";}*/);};};/* when not call with -e xxx,xxx    just clean */bootenv: ({name = "swu_param";value = "";},{name = "swu_software";value = "";},{name = "swu_mode";value = "";},{name = "swu_version";value = "";});}

2、sw-subimgs-ab.cfg
