TF330 Akiko Rev 0 Issue (SOLVED)

[terriblefire]

I just confirmed that the other non working boards also have akiko rev 0. I think we have the culprit.

I'll get my hands on one and see what gives.

Has anyone ever tried a SX32 Pro on a rev 0?

Ok, thanks Alen, that's good input, at least we know the direction to look in..

I got the CD32 from nils. As suspected, his console also has the Akiko rev 0, which is why the card didn't work.

I Too now have one person who bought a TF330 and it did not work with his CD32 ...it has the Akiko Rev 0

sent my board to Steve already, we'll know more soon..

Does whichAmiga report Akikio version? If so maybe worth making a CD image for people to test

My fear is that this Akiko doesn’t like me turning off the 020. It would be useful if someone could test an SX32 on one

I already tried Which Amiga Steve few days ago and it just reports that it is an Akiko C2P no Version number

Yeah hope someone can test an SX32 030 on the Rev0..perhaps that`s why Commodore did a Rev A ..imcompatible?

Also my method of physically looking at the Rev on chip can be done in minutes just by opening the top case and hinge it against something no cables need to be removed then lifting the two tabs on the top shield by the power and Video ports then remove the one top shield screw by the expansion port, then gently lift up the top shield enough so you can see and read Revision on Akiko, will just need a small light to view it

Commodore usually had a way of IDing chips. Probably never documented in the CD32

The first longword of the Akiko registers has a magic number

https://github.com/tonioni/WinUAE/blob/master/akiko.cpp

B80000-B80003: C0CACAFE (Read-only identifier)

I wonder if it’s different between revisions?

A quick email exchange with Toni Willen..

The ROM only checks for CAFE not the COCA...

@alenppc can you check address $B80000 on the ReV0 please with DiagROM?
