azure - 软件描述中 'postinstall' 所需的功能 "adu-swupdate.sh"不存在

Question

我目前正在使用层meta-azure-device-update 和meta-swupdate 进行Azure 设备更新。我想运行安装后脚本。我关注了下面提到的来源:

1.sw-描述.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

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

所以，经过几个小时的探索和阅读 SW-UPDATE Wiki 的每一页，我发现每个函数都有处理程序，我们在使用它之前必须启用它。

您可以在这里阅读有关它们的更多信息。 https://sbabic.github.io/swupdate/handlers.html

这些处理程序可在 meta-swupdate/recipes-support/swupdate/defconfig 中找到

因此，要启用安装后脚本功能和预安装脚本功能，您应该在以下位置编辑此 defconfig 文件

CONFIG_SHELLSCRIPTHANDLER=y

这将为您的 swupdate 启用后安装和预安装脚本功能。
