Ah ha! The TFT Lives!

The breadboarded ARM DRO can finally get the TFT display to display something over the SPI interface. I've used the same x*y colour map:

This is good news as it's a movement forwards. It turns out that I wired the JTAG signals to some of the TFT interface signals and the JTAG was turned on by default. As I want to keep the JTAG debug facilities I'm going to rewire the interface on the PCB. I will mill another PCB at some time, so it doesn't matter too much.

I now need to get the touch screen controller talking, then all the hardware will be talking. Then on to make some more complex firmware to do DRO type stuff.
