Re: A24 DMA into the hk nitro 60

[npr@jach.hawaii.edu (Nick Rees)]

Whilst not exactly on the topic of A24 DMA mapping of the hknitro, I
was wondering whether anyone was keeping a track of changes made to the
hknitro60's bsp, in the same way Argonne does for their Motorolla
boards.

I say this since I have a couple of Nitro's and a still outstanding
problem about, I think, and interaction between the nitro60 and an
Inmos B016 transputer link interface. To get these boards to live
together at all I had to comment out the checking of sysFail at boot
time on the Nitro 60 BSP. However, having done this there are still
problems where the Nitro60 remains unresponsive to the console for
seconds at a time despite spy saying there is zero activity going on. I
suspect a bus problem, but have not had the time to connect an analyser
up and find out.

So, if anyone is willing to send me there diffs/modifcations/deletions
etc to the Nitro60 bsp, with a bit of reasoning behind it, I would be
most grateful.

Cheers,

Nick Rees
