引导时自动运行EFI应用程序 [英] Running an EFI application automatically on boot

问题描述

我可以在UEFI环境中构建并手动执行.但是，我想让我的应用程序在启动时自动执行.

I can build and manually execute an EFI application in a UEFI environment. But, I'd like to have my application executed automatically at boot time.

是否可以告诉引导加载程序执行此操作，还是需要将我的应用程序转交给驱动程序以使其自动执行?我缺少的FDF，DEC，DSC或INF文件中可能有某些条目吗?

Is there a way to tell the bootloader to do this or do I need to turn my application in to a driver to have it automatically executed? Is there maybe some entry in an FDF, DEC, DSC, or INF file I'm missing?

推荐答案

您可以将startup.nsh脚本文件添加到UEFI Shell引导驱动器中，以调用您的应用程序.

You can add a startup.nsh script file to your UEFI Shell boot drive that calls you application.

以下链接应作为在Shell中使用脚本的方便参考: UEFI Shell和脚本.专门查看第3节(EFI Shell脚本).

The following link should serve as a handy reference for working with scripts in the shell: UEFI Shells and Scripting. Look at section 3 (EFI Shell Scripts) specifically.

但是，如果您实际上是在构建自己的固件，则还可以考虑创建可启动的EFI映像并将默认启动选项设置为此二进制文件.如果将二进制文件作为ROM的一部分包含在内，这将非常有用，但是设置文件系统可能会有点麻烦，因此将其视为正常的引导选项.

However, if you are actually building your own firmware, you can also look at creating a bootable EFI image and set your default boot option to this binary. This is most useful if you are including the binary as a part of your ROM, but it might be a little involved to set up the filesystem so that it is seen as a normal boot option.

此外，如果您可以完全访问固件源，则还可以从BDS驱动程序加载并调用二进制文件.我不建议您采用这种方法，除非您的目标是创建一个不会启动任何其他映像的独立设备.

Also, if you have complete access to your firmware source, you could also just load and call your binary from your BDS driver. I don't recommend this route, unless you are specifically aiming to create a standalone device that will never boot any other image.
