You only need USB + power + FTDI cable to use the MFG tool and see output on console.
Can you describe what exactly is happening? When you switch on power of OpenRex, can you see correct USB driver initialized and can you run MFG Tool ok? Where exactly it is stacked?
PS: Try to measure TX pin by oscilloscope, just to be sure there is nothing wrong with FTDI cable or console settings (or boot the board by standard way).
