Porting Fiasco+L4re to DaVinci DA850 - Linux time wrong

I've now got L4Linux running on top of Fiasco+L4re on the DA850. However
there appears to be something wrong with the time.  Time seems to be
passing at a rate of 10-1 (i.e. 1 elapsed second == 10 reported seconds)
in Linux.  If I change the default Hz rating  the L4Linux config (from
100Hz) in either direction L4Linux either hangs or slows down
dramatically.  If I change the period in the timer driver (in the Fiasco
bsp directory) things hang earlier.

For the Fiasco BSP I'm using:
      * timer_tick-single-vector for timer_tick_IMPL,
      * clock_generic for clock_IMPL,
      * a da850 timer driver for timer_IMPL.

Can someone enlighten me as to how it should work?


Thanks
