I'm afraid my last update didn't work... slewrate and altUSB settings was NEVER used in the current version.
I read the manual, and I had to change the 1-wire speed to flexible (not regular which it always has been until now). I have made some updates here, but I couldn't checkin the changes to the cvs right now... don't know why... But I'll try again tomorrow morning. /Christian > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:owfs- > [EMAIL PROTECTED] On Behalf Of Christian > Magnusson > Sent: den 3 juli 2007 15:13 > To: [email protected] > Subject: Re: [Owfs-developers] NSLU2 and DS2408 > > > It sounds like you have the problem with AAG products and USB-adapters > like > many other people have stumbled into. > http://www.aagelectronica.com/aag/en-us/pg_10.html#Q29 > > You could try to start "owserver -u --altUSB" and then tweek the usb- > timings > and see if it solves the problem. > Edit the file /opt/etc/owfs/owserver and add > OPTIONS="-u -p 3002 --altUSB" > > Restart owserver > > # kill-owfs > # run-owfs > # echo 3 > /tmp/1wire/bus.0/system/adapter/pulldownslewrate.0 > (Valid: 0-7) > # echo 10 > /tmp/1wire/bus.0/system/adapter/writeonelowtime.0 > (Valid: > 8-15) > # echo 8 > /tmp/1wire/bus.0/system/adapter/datasampleoffset.0 > (Valid: > 3-10) > (Those are the default values...) > > First try if --altUSB flag helped you... if not, try changing the > values to > some different... > Especially try change the slewrate to get rid of the signal reflections > and > read errors. > The meaning of value 0 to 7 is described below. > * PARMSET_Slew15Vus 0x0 > * PARMSET_Slew2p20Vus 0x1 > * PARMSET_Slew1p65Vus 0x2 > * PARMSET_Slew1p37Vus 0x3 (default) > * PARMSET_Slew1p10Vus 0x4 > * PARMSET_Slew0p83Vus 0x5 > * PARMSET_Slew0p70Vus 0x6 > * PARMSET_Slew0p55Vus 0x7 > > > What kind of errors are detected? > # grep -v " 0" /tmp/1wire/bus.0/statistics/errors/* > > > /Christian > > > > -----Original Message----- > > From: [EMAIL PROTECTED] [mailto:owfs- > > [EMAIL PROTECTED] On Behalf Of Giuliano > > Sent: den 3 juli 2007 12:40 > > To: [email protected] > > Subject: [Owfs-developers] NSLU2 and DS2408 > > > > Hi, > > i just installed an NSLU2 with unslug 6.8. > > My network is very simple, i need to control a DS2408 , the > connection > > to the > > NSLU2 is realized via an DS9490R.
