需求#xff1a;如题#xff0c;串口需要输出logcat的系统全量日志#xff0c;我这里边是把logcat日志定向到了/dev/kmsg从而使logcat跟kmsg一样通过串口输出。

需求如题串口需要输出logcat的系统全量日志我这里边是把logcat日志定向到了/dev/kmsg从而使logcat跟kmsg一样通过串口输出。
改动如下
diff --git a/rootdir/init.rc b/rootdir/init.rc
index 3cf6ffc35..12337986a 100644
--- a/rootdir/init.rcb/rootdir/init.rc-399,8 399,10 on initchmod 0660 /sys/power/wake_lockchmod 0660 /sys/power/wake_unlock chmod 0660 /proc/kmsg# Start logd before any other services run to ensure we capture all of their logs.start logdstart logkevin# Start lmkd before any other services run so that it can register themchown root system /sys/module/lowmemorykiller/parameters/adjchmod 0664 /sys/module/lowmemorykiller/parameters/adj-423,6 425,7 on load_persist_props_actionload_persist_propsstart logdstart logd-reinitstart logkevin# Indicate to fw loaders that the relevant mounts are up.on firmware_mounts_complete-1058,6 1061,11 service ueventd /system/bin/ueventdseclabel u:r:ueventd:s0shutdown criticalservice logkevin /system/bin/logcat -f /dev/kmsg *:Dclass mainuser rootgroup logd system
