For reference, this is what I', currently trying with:

Reading the Cyrus TRM, I’m trying to do some CPU comms. I can get the value of SIG1 is 0xdead. SIG2 comes back as 0xafbe. And hwrev comes back as 0xbeef. Depending on how I do it. SIG2 should be 0xbeef. And hwrev should be the hardware revision. So, not 0xbeef at least.

Does anyone have a snippet ...

Okay, found the issue.

When getting the memory attributes, you have to check for the MEMATTRF_NOT_MAPPED attribute, and not 0.


xmematt = IMMU->GetMemoryAttrs((APTR)0xF4000000, 0);

// if(0 == xmematt)
if(xmematt & MEMATTRF_NOT_MAPPED)
{ // if Xena has no memory space..
IDOS->Printf ...

I wanted to play with some Xena stuff again. Turns out Lyle's old examples from the wiki, and some other examples I had, now throws a DSI when writing to Xena. What's up with that?

I tried opening that xena.resource/XR_DATABUS, which worked, but still got the DSI. The DSI can be ignored, but it ...

Regarding Cairo, salass00 has a port on GitHub, which I’ve compiled including fontconfig support. You can find it here: https://sourceforge.net/projects/odyssey-os4-dependencies/files/

The reason it’s not on os4depot yet, is because I haven’t tested it.

I also created a docker image with gcc 8.2.0 ...

I think you need to provide a few more details in order for someone to be able to look into it. How do you copy, Workbench or command line? Do you get a crash log? Do you get the same crash in command line and Workbench? What other cards do you have installed? Which OS 4 version? FE?

I'm can't ...

Yeah, I really like the serial logger regarding its real world usability. But like you say, it ain't super flashy. A flashy LED thingie would be flashy, but less usable.
I have the prototype board, so I might solder something, although I'm a bit reluctant, and slow to start. Also thought of some ...

Okay, so, basically, what you're saying is that there's nothing really interesting to do with Xena without actually digging out your solder iron, order some chips and build away? Because there's no real way of transferring any useful data from AmigaOS to Xena and back.

Now, I didn't buy my X1000 ...

In Yahoo Groups A1-X1000 there should/might be some example programs for Xena.
Yeah, I saw that, and applied for membership – however no reply as of yet. Applied a week ago or so.

So, this GPIO on PA6T - should that be faster than flipping one bit on the localbus? All I've heard is how slow the ...

In the autodoc for elf.library the DLOpen function is said to require an ELF handle:
RootHandle - The ELF handle of the program using this function.
The user program is responsible for passing this, which MUST be
a valid elf handle and MUST be this program's elf handle, plus
it must have been re ...
