Trying to work out why an SD card built from scratch won't boot
Looking at the demo card (which boots fine) there is no recognisable IVT at 0x400 (this area is all 0)
Anyone know why?

OK - my fault
I was mounting the SD card as a disk in the hex editor - I guess this was causing it (or the USB driver ?) to hide anything not in a partition
Dumping the SD card to a file using dd and looking at that reveals the expected IVT
Retrieving data ...
