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*
