移植openharmony之启动shell服务
接上篇已经添加好init进程，但是目前还是无法进入终端，现在就来添加进入shell终端的步骤，首先拷贝源码中hisilicon配置文件到我们的目录中，然后删除多余的文件，只保留我们需要的文件即可
cp hisilicon/hispark_taurus_linux/init_configs xingyun/t113_nand/ -r修改如下文件，添加需要拷贝的文件
diff --git a/vendor/xingyun/t113_nand/BUILD.gn b/vendor/xingyun/t113_nand/BUILD.gnindex e39d9c2a82..bc7de55655 100755--- a/vendor/xingyun/t113_nand/BUILD.gn+++ b/vendor/xingyun/t113_nand/BUILD.gn@@ -1,4 +1,9 @@ # Copyright (C) 2020 Hisilicon (Shanghai) Technologies Co., Ltd. All rights reserved. group("t113_nand") {+ deps = [+ "init_configs",+ "init_configs:init_initd",+ "init_configs:init_fstab"+ ] }然后重新编译，可以看到多出了这么几句话，会将你的文件自动拷贝到对应的目录中，
然后直接运行，可以看到，能正常进入终端了。
至此，一个openharmony基本系统已经移植完成了。其中需要注意的点为init_t113_linux.cfg文件里面，
{ "jobs" : [{ "name" : "pre-init", "cmds" : [ "mkdir /storage/data", "chmod 0755 /storage/data", "mkdir /storage/data/log", "chmod 0755 /storage/data/log", "chown 4 4 /storage/data/log", "chmod 0666 /dev/binder", "mkdir /storage/data/softbus", "chmod 0700 /storage/data/softbus", "chown 7 7 /storage/data/softbus", "mkdir /storage/data/system", "mkdir /storage/data/system/param", "chmod 0755 /storage/data/system/param", "mkdir /storage/data/timertask", "chmod 0755 /storage/data/timertask", "chown 7 7 /storage/data/timertask", "chown 4 4 /dev/hilog", "chown 4 4 /dev/hwlog_exception", "mkdir /userdata", "chmod 0777 /userdata", "mkdir /userdata/photo", "chmod 0777 /userdata/photo", "mkdir /userdata/thumb", "chmod 0777 /userdata/thumb", "mkdir /userdata/video", "chmod 0777 /userdata/video" ] }, { "name" : "init", "cmds" : [ "start shell" //这里如果是只保留一个，不能有逗号，否则无法解析启动，可以自行测试 ] }, { "name" : "post-init", "cmds" : [] } ], "services" : [{ "name" : "shell", //需要注意ttyS0,需要修改为板卡对应的串口 "path" : ["/sbin/getty", "-n", "-l", "/bin/sh", "-L", "115200", "ttyS0", "vt100"], "uid" : 0, "gid" : 0, "once" : 0, "importance" : 0, "caps" : [4294967295] } ]}接着再来移植一下与日志服务相关的内核文件。轻量化内核日志服务代码包含drivers/staging/hilog和drivers/staging/hievent，执行如下命令
cp -r linux-5.10/drivers/staging/hilog linux-5.4/drivers/staging/cp -r linux-5.10/drivers/staging/hievent/ linux-5.4/drivers/staging/修改如下几个文件

然后修改如下几点，或者确保有以下几点存在
