Hy all ,

Is there a way to adjust the RTAI scheduler base timer? What's the value for 
the default scheduler frequency? i'm using a TS7300 that for a 300uS recurent 
task generates a jitter of more than 106 uS so it is no more a hard real time 
system. How can i modify the configuration files to modify the value of the 
standard tick from 100 to other value, and the CPU freq from 983KHz to 166MHz. 
(Should it be as it is????)

Adeos: Domain RTAI registered.
RTAI[hal]: 3.2 mounted over Adeos 2.4r17c3/arm-ep9301.
RTAI[hal]: compiled with gcc version 3.3.4.
RTAI[malloc]: kmalloced extent c1680000, size 131072.
RTAI[malloc]: loaded (global heap size=131072 bytes).
RTAI[sched_lxrt]: loaded (PIPED, UP, KERNEL SPACE).
RTAI[sched_lxrt]: timer=periodic (TIMER1),.
RTAI[sched_lxrt]: standard tick=100 hz, CPU freq=983040 hz.
RTAI[sched_lxrt]: timer setup=3052 ns, resched latency=3052 ns.
configured SFTWR_LCK
configured DEVICECFG register
configured PORTB_DDR register
PORTB_DATA opened for usage


Thank you.
