Bertl_oO: the Beta I currently have does not manage to train the link to the sensor anymore
00:26
anuejn
any debugging hints?

(the power supply seems to be a bit on the low side but not too much (5V rail at 4.8242V)
00:31
Bertl_oO
what output do you get during training?

Bertl_oO
that looks very much like a contact problem, i.e. two LVDS pair have bad contact
00:38
Bertl_oO
try to clean the connectors on the interface board as well as the mating connectors on main and sensor board
00:38
Bertl_oO
best with isopropanol or similar and a brush
00:41
anuejn
ah I see
00:41
anuejn
will try
00:42
tpw_rules
how can you tell?
00:47
Bertl_oO
well, the training adjustment looks reasonable, except for two pairs and the final check also confirms all channels except for two which didn't make the training
00:47
Bertl_oO
so chances are good that the only problem here is a bad contact between FPGA and sensor
00:48
Bertl_oO
of course, it could be something more serious as well, but that's what I would check first

tpw_rules
the result should be 0xFFFFFFFF if they all worked? i am trying to figure out how to interpret the results. it will be important for development of my own algorithm
