Question

i have linux os on my leopard target board with tms320dm368 processor. its a raw board with only kernel and rfs. there is no linux distribution (ubuntu,fedora,red hat etc) on the target board. I created the script file as following

#!/bin/sh
echo "my application is here"
./helloworld  # helloworld is our application

after creating the script file i copied it in init.d
I gave the command chmod +x /etc/init.d/vcc_app (vcc_app is the name of script which I have created)
Then I gave the command ln -s /etc/init.d/vcc_app /etc/rc.d/vcc_app (rc.d is the run level directory)

但当我重开董事会时我的申请书不是自动执行的有人能帮我吗?

Answer 1

您应该将脚本放在 / etc/rcX.d/ vcc_app 中, 在您想要执行的英寸级别上更改 X, 如果您想要在英寸 5 上运行, 那么脚本应该放在 :

/etc/rc5.d/vcc_app

欲了解更多Init 级别信息, < a href="http://www.krishnababug.com/2009/04/what-are-init-0-init-1-init-2-init-3.html" rel=“nofollow”请检查此链接

Also in some distribution you can add a command to launch your script at /etc/rc.local or /etc/rc.d/rc.local, check which files exists and add the command.

了解你董事会上的实际内容将非常令人感兴趣,你声称自己没有分配,但你却使用某种(/etc/init.d),而这种(/etc/init.d)只能用于某种阻力。

所以假设你真的不使用分配, 这意味着你没有外壳, 你没有内置系统。

如果您只需要运行一个应用程序, 就不需要任何 shell 或类似的应用程序 - 只需静态地将您的应用程序连接起来, 并将其作为 /sbin/ init, /etc/ init, /bin/ init 。见 < href=" http://lxr. linux.no/#linux+v3.4/ init/main.c% 20% 20main. c% 3ainit_ post% 28% 29" rel= “ noforpol” >linux 内核元. c init_ post () 。

Otherwise if you have more than one application, you need an init system. An easy one is uxlaunch, other options include systemd or busybox init. Even with busybox init, you still don t necessarily need a shell on your system.

市场中有几个装置在无壳的情况下运行Linux,包括许多电视机。
