@ Casey,
So what's the skinny on the DIP socket extender you fab'd up?
My actual develpment ended at that point. I had enough mega code to test the config I was going to use, but I had speed concerns that i think I had a HW workaroud for but I've got to get the bus lines up to a perf board to dev anything further.
Looking at that Pico Pi, that fixes a lot of the workaround HW I was considering, and if I go that route, I'm back to square one.
Either way to test PH I emulation function we've got to get interfaced with the busses.
?I dont know MP LAB source or Python, or what it would take to port Skip's Xcat source to Python.
The detect address and serve data routines should be a good template. Remap the GPIO lines to the X9000's buses and put a valid codeplug in memory should be a solid start.
@ Dennis,
It just occured to me....I'm guessing from the references to memory allocation in a previous post you are perusing the Hitachi's data Handbook? IIR, there are several internal memory configs depending on the chip version, Even one w/masked OTP ROM.
I dont recall that the X9000 has that version. Good thing, no telling what we would run into...lol
