AIBB looks OK and all tests run fine.

I have just experienced the same issue I had on the A500+: every time I write to the CF, it gets totally corrupted.

OK, I reconfigured the expansion to 1 MB slow and the CF write issue seems gone.

I have tried the Memory Test in SysTest and with 1.5MB it fails with X's for all bits right at the start of the 0xC0000 range, weird.

Did you mean 0xD00000? Either way if alenppc isn’t seeing the issue I’m betting you have an issue like a short somewhere on the address bus.

I will check again tonight and post a pic of the failing test.

I don't think I have any issue on my machine, as the full 1.5MB range tests fine with the original 68000 CPU and 1 MB seems to work well with the TF card.

Some guy was mentioning in the PeteAU's expansion thread on EAB that to get a 100% working setup he had to use the latest bus JED but the previous RAM JED. Does that make any sense?

It will be a short on the TF530 if there is one

I will take another look at this also this weekend to see if I can reproduce it by booting Lotus II from WHDLoad. To be honest I haven't tested every game, but I've run Nemac IV, Frontier and a few others.

Hello I know you have a lot going on, so just wondering when the TF534 might be released for people to build.
Amazing work btw!

I'm planning to release them when I am sure i can get a set of gerbers that will work. I'll also sell what i have on eBay at the same time.

I've checked again and it fails in the 0xC00000-0xC7FFFF range, see pic (please ignore awful video quality):

Should I try this?
