Hi ,
I am working on a Boot manager
I have following set-up
in USB i have directory EFI->BOOT->Bootx64.efi(my EFI)
My EFI does load an image, before that I am trying to
EfiBootManagerRefreshAllBootOption () I am trying to refresh all but option
.but it hangs on EfiBootManagerRefreshAllBootOption () .
I have shared code I have bold and underlined where it is hanging, any
idea what might be the reason?
Here is Code :
EFI_STATUS
EFIAPI
BootManagerMenuEntry (
IN EFI_HANDLE ImageHandle,
IN EFI_SYSTEM_TABLE *SystemTable
)
{
EFI_BOOT_MANAGER_LOAD_OPTION *BootOption;
UINTN BootOptionCount;

UINTN i;
EFI_GUID VarGuid;
VOID* Value;
UINTN Index;

BootLogo = NULL;
Status = gBS->LocateProtocol (&gEfiBootLogoProtocolGuid, NULL, (VOID **)
&BootLogo);
if (!EFI_ERROR (Status) && (BootLogo != NULL)) {
Status = BootLogo->SetBootLogo (BootLogo, NULL, 0, 0, 0, 0);
ASSERT_EFI_ERROR (Status);
}
gBS->SetWatchdogTimer (0x0000, 0x0000, 0x0000, NULL);
gStringPackHandle = HiiAddPackages (
&gEfiCallerIdGuid,
gImageHandle,

ASSERT (gStringPackHandle != NULL);
Print(L"ConnectBootManager\n");

if (EFI_ERROR (Status)) {
//

//Print all BOOT#### Load Options
NameSize = sizeof(CHAR16);

for (i=0; ;i++ ){
NewNameSize = NameSize;
//search all EFI variables
Status = gRT->GetNextVariableName (&NewNameSize, Name, &VarGuid);
if (Status == EFI_BUFFER_TOO_SMALL) {
Name = ReallocatePool (NameSize, NewNameSize, Name);
Status = gRT->GetNextVariableName (&NewNameSize, Name, &VarGuid);
NameSize = NewNameSize;
}
//

break;
}
//skip if not Global variable
if (!CompareGuid(&VarGuid, &gEfiGlobalVariableGuid))
continue;

//print attribute
//print EFI_LOAD_OPTION description
Print(L" %s",(CHAR16 *)(Name+3));
Print(L"\n");
}
}
LoadImageFromFile (L"\\Hello.efi");
