I’ll try the new firmware when I can. I’m unfortunately out all day today and so won’t be able to look at it.

Your investigations are appreciated :D

Well, I've posted my results but as I mentioned, I think the MAX II chip is dying as it keeps forgetting its programming and each read/write to memory is different. I'll have to get another PiStorm before I can test further as I can't tell what's caused by the firmware and what's caused by the failing chip.

Just for fun I tested the memspeed function of ataritest.... Write: ~9MB/s, read: ~11MB/s to/from ST-RAM.. yeah, right. :-)

Just to get this I had to reflash the chip a couple of times.
