how to create environmental variable for Shell

how to create environmental variable for Shell

[Tiger Liu]

Hi, experts:
I have a question about creating shell’s environmental variable.
Such as : StartupDelay

I tried to create this variable at uefi boot phase.
……
              TmpVal = 2;
              Status =  gRT->SetVariable (
                                   L"StartupDelay",
                                   &gEfiGlobalVariableGuid,
                                   EFI_VARIABLE_BOOTSERVICE_ACCESS | EFI_VARIABLE_RUNTIME_ACCESS |EFI_VARIABLE_NON_VOLATILE,
                                   sizeof (TmpVal),
                                   &TmpVal
              );
……

When boot to shell, it still delays 5 seconds.

I tried to use shell cmd ‘set’, then it’s ok, shell’s default delay switched to 2 seconds.

I used dmpstore cmd to list current system’s variables, and found 2 StartupDelay variables:
Efi:StartupDelay
SEnv:StartupDelay

So, my question is:
How to create “SEnv:StartupDelay” variable in UEFI BIOS code.

Thanks

Best wishes,

You need to use the shell's GUID, gShellVariableGuid, if you want to
create a shell variable.

[Jim.Dailey]

Please excuse the stupid email plug-in I have to use that puts the
"Internal Use" line in my text emails. The plug-in does not allow
me to see that text, so I have to remember to remove it every time
even though I never see it.  Sadly, I sometimes forget.

Re: how to create environmental variable for Shell

[Jarlstrom, Laurie]

Hi,
Are you trying to set the Timeout variable (delay to allow user to press a key to go into setup) or the delay for the shell  before executing startup.nsh?
The Timeout variable is a PCD and can be set with: 
     TmpVal = 2;
     PcdStatus = PcdSet16(PcdPlatformBootTimeOut, (UINT16)TmpVal);

This will set the global variable "Timeout" - check with shell dmpstore.

The delay for the Shell can be done when invoking the Shell.efi image with "-nostartup" option.

thanks,
Laurie

Re: how to create environmental variable for Shell

[Jarlstrom, Laurie]

Delay for the shell to start "Startup.nsh" can also be done with the option "-delay :n" where n is the number of seconds of delay, default is 5.

Laurie

Hi, Laurie:
Got it!
Thanks a lot!

I just wanted to revise the delay for the shell  before executing startup.nsh.
