How far have you got with the IDE interface?

Only just seen your posts since I have been away with work.

I started with the hardware which will be required first:
I've already built the hardware interface to use a CF adapter on one
of the DE1/DE2's GPIO ports, have just uploaded a photo:

i=32
It's mainly straight through connections, except for rerouting the
3.3v, and a few other conflicts between the IDE 40pins and the GPIO
40pins.
Can post schematic on weekend if anyone is interested.

Have started on the software, but not complete yet.
Software seems pretty simple:
1. State machine in Gayle(GARY) which is checked by kickstart at
reset time to indicate prescence of IDE interface.
2. another INTREQ and INTENA type registers on gayle used by the IDE.
3. IDE uses INT2 on real amiga, just need to add an extra interrupt
line into the interrupt controller code, at same priority.

Happy to share what info I have unless you have figured it out
already?

Cheers,
Leslie
