Hello,
We have a setup where we're trying to sync a N320 (bitstream WX) using White
rabbit with a OPNT Timing Switch as Master configured as Free Running Master.
+------------------------+ +---------------------+
| | SFP0 |
|
| OPNT Timing Switch |---------------- | N320 |
| | |
|
+------------------------+ +---------------------+
We are trying to run test program `test_pps_input` in order to see if PPS is
working as expected.
When running without any argument, the PPS is correctly detected, I suppose it
is because it uses as time source `internal`.
Then when I try to use `sfp0` as a time source, I observed 2 different
behaviors:
Command run: ./test_pps_input --args="clock_source=internal,time_source=sfp0"
--source=sfp0
1. I get the following message:
[ERROR] [RPC] TDC Failed to reset.
[INFO] [MPM.Rhodium-0.init.LMK04828] LMK initialized and locked!
[ERROR] [MPM.Sync-0] TDC Failed to Reset! Check your clocks! Status: 0x0
[ERROR] [MPM.RPCServer] init() failed with error: TDC Failed to reset.
Error: RuntimeError: Error during RPC call to `init'. Error message: TDC Failed
to reset.
And after this message, the PPS led does not blink anymore.
2.
If I then run again the test after failing previously, this time I don't get
any error message but a exception is thrown because no PPS was detected.
We know that the OPNT Timing switch works when used with a OPNT node, where we
get PPS and 10MHz signals.
Do you think that there could be an issue when N320 and OPNT Switch try to sync
together, or do you have any idea of what I could explore ?
Thank you in advance for any help you can provide me with.
Best,
Julián
