Hi,
I'm getting all zeroes nearly any time there's supposed to be a large
number output to my terminal. Does this sound familiar to anyone?
This happened last night on rsx and is also happening today on xxdp.
example xxdp testing rl02:
DRSSM-G2

Well, if you tell it to use a csr of 0 and a vector of 0, things will not work well. You
also mentioned rsx. What do the error log show in there?

I agree with Johnny; even before I read his post I looked at this and
thought here's a simple case of GIGO :-)
XXDP makes NO assumptions about things like CSRs for devices, and does
almost no sanity checking on input. There's no rule that says a
controller has to be at a particular address, not even necessarily in
the I/O page in Bank 7. When you told XXDP the CSR is at address 0 (by
not entering a different value), that's what it would believe, and it
would happily test whatever is there. In this case, that's real,
existing, working memory, so it won't even fail with a bus error, but it
will read back zeros after it's cleared - exactly as you saw. Even the
elapsed time is genuinely zero, as it's reporting immediately, and all
the other values are the contents of a zeroed memory location instead of
a register.
The fact that your CPU boots XXDP - never mind something more demanding
like RSX or BSD - suggests it (and the memory, disks, etc) is pretty
much working. Retry the RL02 test with proper values.
