Hi ,

I am trying to load an EFI from another EFI, it stuck when LoadImage is
called
both EFI are located on USB .

Here is code snippet


"
    UINTN NumberFileSystemHandles;
    EFI_HANDLE *FileSystemHandles;
    UINTN Index;
    EFI_BLOCK_IO* BlkIo;
    EFI_DEVICE_PATH_PROTOCOL *FilePath;
    EFI_HANDLE    NewHandle;

    UINTN         ExitDataSizePtr;

    EFI_BOOT_LOGO_PROTOCOL          *BootLogo;
    EFI_STATUS    Status;




    gBS->LocateHandleBuffer(ByProtocol,
                            &gEfiBlockIoProtocolGuid,
                            NULL,
                            &NumberFileSystemHandles,
                            &FileSystemHandles);

    for(Index = 0; Index<NumberFileSystemHandles; ++Index) {

        Status = gBS -> HandleProtocol(FileSystemHandles[Index],
                                        &gEfiBlockIoProtocolGuid,
                                        (VOID**) &BlkIo);

        Print(L"after HandleProtocol %x - %r\n",FileSystemHandles[Index],
Status);
        if(!EFI_ERROR(Status)) {


            //check if it is usb
            if(!BlkIo->Media->RemovableMedia ||
BlkIo->Media->RemovableMedia)
            {



                    FilePath = FileDevicePath(FileSystemHandles[Index],
                                            L"Hello.efi");

                    Status = gBS->LoadImage(
                        FALSE,
                        gImageHandle,
                        FilePath,
                        NULL,
                        0,
                        &NewHandle);
                    if (EFI_ERROR(Status)) {
                        if (NewHandle != NULL) {
                            gBS->UnloadImage(NewHandle);
                        }


                        //return (Status);
            }


    }
