[audio-hal-2-0在android系统启动时找不到

Question

我正在为Resenas Rcar-H3开发板构建android 9。构建过程成功。但是，在将映像刷新到电路板上之后，启动过程将无法正常进行。 audioserver由初始化进程重新启动，并通知如下错误：

[  737.947862] init: Service 'audioserver' (pid 2734) exited with status 1

有人可以帮助我吗？谢谢大家！

好像您告诉init启动vendor.audio-hal-2-0，但未提供服务定义。

在您已安装的.rc文件之一中，可能会有这样的呼叫：

start vendor.audio-hal-2-0

您还应该有一个看起来像这样的服务定义文件：

service vendor.audio-hal-2-0 /vendor/bin/hw/<binary>
    <options>

如果不这样做，则需要创建一个，如果执行，则可能未正确安装。您可以像这样在Android.bp模块定义中安装其他服务文件：

cc_binary {
    [ ... ]
    init_rc: [ "vendor.audio-hal-2-0.rc" ],
    [...]
}
