I guess this this is a typo, isn't it? I would expect "periodic" here.

The VxWorks skin requires periodic timer mode. If you don't plan to use
it, drop it from the kernel config . If you do want it, either set
CONFIG_XENO_OPT_TIMING_PERIOD to some reasonable value (see also the
related kernel-config help), or turn the nucleus into a module and pass
the period via the module parameter "tick_arg" when insmod'ing
xeno_nucleus later.

README.INSTALL and TROUBLESHOOTING are the official guides. For the
rest: you are already on the right list. ;)
