I bought programmer, and reverted back to RPi very quickly.

I will share this here, as most people suggesting using Raspberry pi 2+ for programming cplds. It can be done without any issues, I managed to set up exactly in the same way as RPi2+, it is slower, and requires patience for set up, but it can be done. This would make cheapest solution as board cost ...

this isn't bad idea, actually this will definitely minimise the risk to go through same nightmare @alenppc gone through

Or or will increase chances of control, who knows.

I have just realised that I made quite big mistake with picking up RAM chips.
I installed powered by 5V RAM on 3.3V line.
I guess I was lucky that this expansion do work, and it is stable as I di run soak ram test for 6h and didn't see any issues with it.

FlashFloppy supports .st files.

Where did this come from? I wasn't even aware that it existed.

Twitter.

This was prototype.

Out of interest, what were the main challenges in adapting the CD32 360 design to the 1200 from a logic point of view? I've no idea. I've not figured it out/done it yet. I guess this is the bit people dont get. Making the board is kinda easy. Making it work is hard and takes time. There are literal...

Could you do some high Res picture of the board?

I check for bad joins by taking needle and gently tapping each leg (under microscope). I was VERY supprised that I found more than half a dozen legs not soldered property, even if they did look ok from above under cheap usb microscope.

ok. I ran autoconfig and got this : https://photos.app.goo.gl/akyREk8uXiCKHf3C8 So based on your statement, that means it's the address path? the address path from the cpld to the ram chips? I checked continuity from the cpld to the ram chips and they all seem to be connected. Did you get parts fro...
