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
  )
{

  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 (
