I have some issues.
Firmware with 32 cycle release I do get interrupt, but each time I try to even reprogram GPIO for output PushPull or even set 0 as open drain, CD32 crashes.
For any other firmware I even don't register interrupt.
EDIT:
INTSIG1 and INTSIG2 should allways be 1...?
EDIT2:
I pushed changes.
INTSIG1/2 should be inputs.
INTSIG1 = 0 = JOYDAT0
INTSIG2 = 0 = JOYDAT1
Safest thing is to set everything to input except INTSIG8

When I set up interrupt on falling edge of intsig1 then when I read busint as 1 (not the other way round), but when I try to reconfigure D0-D7 to allow write to pin any data on bus I got CD32 crash. I assume Amiga is already doing something else (?) Maybe 32 cycles have passed already and I mess up data bus?

I'd thought EXTI was setup for BUS_INT (pin 61) possibly it can both.
I am expecting 32 cycles to take 2000uS but you can go back to the older one that locks up. Just flash the cpld after boot.

OK i've not had a minute to look at this. I'm tempted to fall back to the SPI transfer mechanism we had in revision 1.

Would it be easier?

Much. But being able to put the ARM on the bus is going to be needed for the CD32 buttons.

Do you think you could share current Rev 2 eagle by any chance.
I was thinking of scaling down this to Minimum Usable Product? So replacing obsolete PS2 to USB HID keyboard and video out?
Do you think there would be value in this?

Give me a day or two and i'll see if its on my laptop
