Hi Jason:
Are there stable model files for packetized correlator on ROACH ? I saw
there are 2 model files in the /roach subdirectory, but with comments of
"lots of stuff here for debug ".
cheers

I have just checked-in the latest versions. F engine is at revision
306 (stable) for ibobs and X engine is up to rev 322g (debug compile)
for roach.
There are two major outstanding issues before the system is deployable:
1) Loss of packets from F engines. There is a loss of data (about 1
Hi. Does anyone know what the status of this is? Does borph on the bee2
work under 10.1?

Hello:
I am new to the list and to ROACH boards so apologies in advance if this
question is misdirected. I am working at Caltech on using a ROACH(1) board
running BORPH via USB. Specifically debian/etch with
kernel 2.6.25-svn1867-dirty1.
Our application requires timestamping FFT data to precisi
Hi Tom
We use hardware time tagging in some of the spectrometers we've built,
accurate to a few nS, described below:
We've implemented time tagging in spectrometers and correlators (we can
send you some spectrometer
designs if you want), by running the ADC sample clock from a
synthesizer loc
I haven't tried it on the ROACH, but we've had great results (i.e.
much better than 1 ms) with the IEEE Precision Time Protocol (using
ptpd, from ptpd.sourceforge.net). You might want to give that a try
before you resort to fancier solutions.

Hi Tom
We use the exact same procedure that you outline below to timestamp
our data and ran into the same problem. It turned out to be due to
integer rounding in Uboot's clock configuration. Please update your
uboot and kernel to the newest versions. I sent around an email on 01

I noticed that message, but I thought you meant "ntpdate" instead of "ntpd"
because you mentioned it in the context of boot-up. It sounds like just
what we need.
I'll work out a plan with my co-workers for updating the board and contact
you if I run into problems with ntpd.
Thanks! And to other
