UEFI Driver/Application

UEFI Driver/Application

[Ivan Novgorodtsev]

Hi,


I want to develop a small security check
for UEFI partition. I want it to be run each time when system starts. My idea was to
create UEFI driver or application (I'm not quite sure what will fit better), because
if I'm not wrong, they run at UEFI Services
level, according to the documentation:https://imgur.com/a/yep2IwB   It will execute,
and the pass control to Boot Manager which launches OS, right? I'm open to
suggestions, if there's more suitable solution. The scripts I want to run in Shell
via
application:

vol > base.txt
vol > output.txt
comp base.txt output.txt

Right now I have also problem with compilation of project. I want to use similar
piece of code like this:

#include <Library/ShellLib.h>

...

EFI_STATUS
EFIAPI UefiMain(IN EFI_HANDLE
ImageHandle,IN EFI_SYSTEM_TABLE *SystemTable)
{
EFI_STATUS Status;
ShellExecute(&ImageHandle,L"echo Hello World!",FALSE,NULL,&Status);
returnStatus;
}

...
My .INF file:
## @file
#  TODO: Brief Description of UEFI Driver BootCheck
#
#  TODO: Detailed Description of UEFI Driver BootCheck
#
#  TODO: Copyright for UEFI Driver BootCheck
#
#  TODO: License for UEFI Driver BootCheck
#
##

I get the following output erros:

1>Flash Image Definition   = c:\myworkspace\Nt32Pkg\Nt32Pkg.fdf

1>    consumed by module [c:\myworkspace\source\BootCheck.inf]

I really appreciate your time and your help with this.
Kind regards, Ivan

Hi Ivan

You need to add the declaration of ShellLib at the Nt32Pkg dsc file.
Other .dsc files maybe usefull to check how to do that. Maybe you will need
to add other packages after adding the ShellLib. So other errors may arise
until you add all the required packages.
