我目前正在使用层 meta-azure-device-update 和 meta-swupdate 进行 Azure 设备更新。我想运行一个安装后脚本。我遵循了以下提到的来源：

1.sw-description.rst https://git.rigado.com/vesta/swupdate/-/blob/acf50e361a8752db48e69ffe3c20a167c402d35f/doc/source/sw-description.rst#board-specific-settings

2.adu-swupdate.sh https://github.com/Azure/iot-hub-device-update/blob/main/src/adu-shell/scripts/adu-swupdate.sh

映像已成功构建，我能够在我提供 Azure 设备更新的 .swu 文件中找到 adu-swupdate.sh。安装失败给出以下错误：

Sep 21 07:21:30 rpi AducIotAgent[281]: -> 07:21:29 PUBLISH | IS_DUP: false | RETAIN: 0 | QOS: DELIVER_AT_MOST_ONCE | TOPIC_NAME: $iothub/twin2021-09-21T07:21:30.2396Z [E] Install failed, extendedResultCode = 1 [Install]

sw-update 日志如下：

因此，经过数小时的探索和阅读 SW-UPDATE Wiki 的每一页后，我发现每个功能都有处理程序，我们必须在使用它之前启用这些处理程序。

你可以在这里阅读更多关于它们的信息。https://sbabic.github.io/swupdate/handlers.html

这些处理程序在 meta-swupdate/recipes-support/swupdate/defconfig 中可用

因此，要启用 post 和 preinstall 脚本功能，您应该在以下位置编辑此 defconfig 文件

CONFIG_SHELLSCRIPTHANDLER=y

这将为您的 swupdate 启用 post 和 preinstall 脚本功能。
