Re: Urgent help -UefiBootManagerLib and LegacyBootManagerLib issue

[Saqib Khan <saqib.khan2011@gmail.com>]

Hi Andrew,

I think I did not address my problem well in my previous email.Please take
a minute again to understand my problem.

here is my scenario

 have following  lib added to my *.inf file
[LibraryClasses]
  HiiLib
  DebugLib
  UefiLib
  MemoryAllocationLib
  UefiBootServicesTableLib
  UefiApplicationEntryPoint

*UefiBootManagerLib  LegacyBootManagerLib*
  UefiShellLib

And here is piece of code I am trying to compile

EfiBootManagerConnectAll ();
EfiBootManagerRefreshAllBootOption ();

BootOption = EfiBootManagerGetLoadOptions (&BootOptionCount,
LoadOptionTypeBoot);

Status = gBS->LocateProtocol (&gEfiLegacyBiosProtocolGuid, NULL, (VOID **)
&LegacyBios);

it Compiles successfully but EFI hangs at

*EfiBootManagerRefreshAllBootOption () *
When I remove * LegacyBootManagerLib* Libraries it does not hang

I think I missing something in it may be i need to add CSM libraries in my
EFI?

I also tried NULL library resolution in DuetPkgx64.dsc like this

MdeModulePkg/Application/BootManagerMenuApp/BootManagerMenuApp.inf {
    <LibraryClasses>

NULL|IntelFrameworkModulePkg/Library/LegacyBootManagerLib/LegacyBootManagerLib.inf

  }


If you still think that is a CSM issue then i will be go for another system
as i am doing my development on physical system.


*Thank you*
