Re: The TF536 on a CDTV
OK i have a hunch i know whats up.
Looks like the CDTV is trying to DMA into fastram. thats never going to work.

Re: The TF536 on a CDTV
So now i need to figure out how to get the driver to use chip ram only and we're good. Or mark my ram as non-dma somehow.

Re: The TF536 on a CDTV
So in order to make this work we need to patch the call that allocates RAM for the scsi buffers

Re: The TF536 on a CDTV
Looks like it. I'd expect it to AllocMem then set the address in DMAC. Seems like its separate from the disk buffers that get allocated in the mountlist as the mountlist BufMemType makes no difference to the type of ram allocated.
Anyways that was a useful exercise because i got the bus ARB nailed.

Re: The TF536 on a CDTV
Is it possible to make TF520 work on CDTV?
that would give us a little boost

Re: The TF536 on a CDTV
It should already with the TF534 sources.
EDIT: but its not faster than a standard 68000.
