hi,
hmmm... then we should move the sde990 then, for at least for the tofino1
model to work?
lemme ask again if the aps guys progressed with the bsp for the sde990 from
their side...
br,
cs

Never mind. I was using an older version of freertr, namely the one I
used in the demo of running RARE on the model. Remember that the ping
worked back then? That was because of this behaviour that freertr
considered the port to be up. Presumably, this demo would no longer
work with the current version.

well, so this "start in down state" changed recently, carmen reported about a
thing...
so on the older jars, it's normal, that you noticed something else... :)

Ok, so this is issue is solved :)
hmmm... it'll turn out... (in cast of asic, it should, yess...:)


So can you now please check whether the oper status of your ports on
the model is "UP" (seen from the UCLI) when you expect it to be ? This
is really my main concern for now :)

i see on my model vm running sde990 after java -Xmx512m -jar rtr.jar test
tester p4lang-rout001 other p4lang301.ini wait

Yes, I know it works on 9.8 and 9.9. Sorry, I should have said so. Do
you have 9.7.x to check, too?

it's my model on 9.7.2 and yess, and i also got a lot of state messages at
the beginning but after that, every port went down...

Ok, so it's not just me. That's good to know but it also means that
RARE doesn't work on the model prior to 9.8.0 :( It's probably
pointless to ask Intel for a fix, even if 9.7 is LTS. They should be
able to back-port it from 9.8, I guess...

BTW, the Tofino2 model doesn't work either. With that, the ports are
also always down but they also report "NO" in the RDY column :( This
is also present in 9.8 and 9.9.
