The msr program runs, but it records nothing...
Are you monitoring active SpaceWire link(s)?
Have you started the device-under-test properly; is its software running?
Has your device-under-test livelocked or deadlocked?
Was the MSR powered and running before the SpaceWire links in question were initialised? Check that
the MSR’s front-panel display shows the link speed in each direction and that the two endpoints are
exchanging NULLs, if nothing more.
Have you filled up the disk on your host computer?
My SpaceWire link(s) are disconnecting unexpectedly...
Is your device-under-test properly grounded to your DSI? SpaceWire requires a ground reference to be
connected through the outer shield of each SpaceWire cable. If this is not done, the common mode
potential might be too high, leading to seemingly random errors or sensitivity to external electromagnetic
interference.
The Synchronised Outputs option of the 4Links Diagnostic SpaceWire Interface works by inserting short
idle periods into the SpaceWire signals, and for link speeds less than 100 Mb/s this can cause the
disconnect timeout to be exceeded. See the DSI manual for further information.
