Well, there’s wisdom there, for sure! :-)
Last night I also managed to put a new RSTS image, sysgen’d with the
non-overlapped DK driver, on a different physical pack. It behaved exactly the
same way on the real hardware (looping, counting up errors) on boot.
So I think now overlapped vs. non-overlapped DK driver is not the issue, and
media and image transfer fidelity are not the issue. A memory or MMU problem
would be consistent with what has been seen so far, so I may bark up that tree
a little more today.
Paul, any additional suggestions for things to look at in ODT to try and wring
out more information on the specifics of the fault?
I did get some MACRO CRC-16 sub-routines coded up last night while waiting for
various transfers, so I think I’ll go ahead and finish up the standalone CRC
dumper utility today.
Lastly, a 5V-tolerant USB FIFO breakout board is supposed to show up in the
mails today. If that works out as simply as I hope to interface with a DR11-C,
I should have a much better way to blast bits on and off the machine soon.
cheers,
