I use the ntpclient from Dolittle to have the fox synched to ntp server.
All looks ok if the ntpclient is running from almost 20 minutes and I
have made a resync to server using ntplient -s -c server.
The problem arise if I need to reboot the board.
I can setup with adjtimex the last frequency setting from the log
before reboot, immediatly after rebooted the board,
but from log I can see that time start to accumulate a big error,
and without any manual adjust, it take hours to sync again to ntp
server.
to be more clear I start ntpclient in /etc/init.d/rc
and this is the log
# box [( -4.085 , -726.2 ) ( 2.839 , 708.2 )] delta_f 0.058
computed_freq 1548204
39536 42593.068 1090.0 34.0 -9.0 427.2 1552036
# box [( -3.768 , -732.5 ) ( 2.590 , 656.5 )] delta_f 0.061
computed_freq 1544211
39536 42623.079 1113.0 35.0 -38.0 381.5 1548204
I setup the boot script /etc/init.d/rc in this way:
/bin/mount -t vfat /dev/sda /mnt/1
/mnt/1/fox/adjtimex -f 1524916
/mnt/1/fox/ntpclient -s -h 192.167.189.69
/mnt/1/fox/ntpclient -l -i 30 -h 192.167.189.69
but after reboot I get this in ntpclient.log
just few minutes after soft reboot this is the status:

Anybody else use ntpclient and has the same problems?
I use a fimage built with kernel 2.6.x, vhdl support etc..
