[terriblefire]

Its probably about time i merged the branch into develop
.

EDIT: Done.

There will be about 100 Delfina's available soon,
Will let You know when these pop up, if someone is interested

Interested. I've been following the a1k forum, but did not see any recent progress.

That was quick, hopefully they build again.

There will be a batch of bare pcbs available soon,
JEDs for MACH Chips are also available, so highly likely You'll be able to build one before Prelude pops up.🤔

As far as I understand issue with jumping mouse affects certain CD32 boards only.
Only mouse is affected, RTC is handled correctly, and it looks like only counters are affected.
Same set of TF330 works fine on one machine, but fails few others.
As far as I understand stm32 is doing its job correctly, and any changes to extend timings on each stage of process doesn't fix issue.

Therefore I assume issue is with cpld logic.

@terriblefire

If you had some time and/or will, could you have a look at https://github.com/arkadiuszmakarenko/T ... main_top.v
and look for obvious mistakes there? Or hints what I could try? Effect is like override wasn't taking fully effect? Like PUNT was ignored every so often?

only issue i see is that things are combinatorial logic when possibly clocked logic might be better

Can you tell which CD32 boards could possibly be affected?

@kulamario had exactly the same setup, and it worked ok on one CD32 but didn't on other.

both are the same revision rev3

I thought it was akiko's fault because one is rev-0 and the other is rev-A and for me it works on rev-A
after talking to alenppc we found that this is not it
because alenppc has some cd32 and rev0 and rev-A and it doesn't work on any of them
