I’ve been trailing the webs for stuff like that. There’s Lyle's buffer example on the
AmigaOS wiki, and I also found some posts in the Hyperion forums with more info. I’ve been thinking of trying to summarise that info into something, we’ll see if I ever get to it.
But in general on the X1000 it seems the local bus have some severe limitations. But there are ways to send data to the chip in a slow way using the jtag. But hopefully being able to compile on the amiga will make it less awkward to test things out.
Also, there are some old Xmos resources for our chip that explains the basics. So those are rather good.
