Data logging in 200ms steps only -> ???

[j.oe]

When I've used data logging first time this season, I noticed a weird behaviour of the ECU's logging activities. If I download logging data as usual, there comes a bunch of files which all contain logs of 200ms duration only. File names of about the half of the files begin with "NoRTC...". If logging is activated at stopped engine by setting all parameters accordingly like 0 rpm Start Engine Speed, -25% TPS and so on, in the right bottom part of the SCal screen the "logging active" parameter always is alternating between "IDLE" and "ACTIVE".
No further longing with longer records is possible there.

FW v1.64 (same at 1.50)
Real Time Clock set
Proper Logging setup programmed
All log sessions and logbook cleared

Any idea how I get this sorted ?

Got the problem solved right after having had finished the post:

Parameter values for stop logging conditions must not be set higher than those for start.

Works fine now !
