Anyone have experience with the Moto 88k VME boards? I have an MVME197LE that I?m trying
to bring up but it?s staying in BRDFAIL, while SYSCON and RUN are green and pressing RESET
appears to work.
Nothing on console at all. (via a 712 transition module)
Same behavior with the NVRAM removed.
I do have the mezzanine card which has stayed affixed with an interesting inter-board
connection. (Is this separate-able? Should it function without this DRAM?).
I?ll dive deep into debugging this, but if anyone has some tips or experience they could
share it would be appreciated!
Thanks!

Make sure the configuration switch for system controller matches the slot
it's in. Fixing the NVRAM seems like a good next step. Not sure I'd remove
the memory mezzanine, I don't think the board can do much without it.

Even with a dead battery you should have seen console output. I would check
the serial cable, p2 adapter and 712 console port jumpers first.
You could try to boot directly from the eprom which holds the 197bbug(using
the DIP switches) in case the 197bug has been flashed with custom
firmware(never seen this, but who knows). You can remove the 297 expansion
card as 197 has its own memory soldered on the back-side.

Some progress tonight. Getting this on console with the memory mezzanine disconnected
(see below).
Regardless of what I type I get the Framing Error response and no echoing.
Thanks for any more insights,
Ryan
