Sorry, I dodn't know which sub-topic to place it under!

Specifically about placing the ldr pc,[pc,#-0xFF0] instruction in the IRQ
offset of the interrupt table. I am finding it doesn't work for some reason,
and wondered whether this was a feature of the EP93xx device. Anybody know?

I have plenty of "standard" IRQ implementations, I also have the
Sloss/Symes/Wright book, which contains quite a lot of information. Thanks
