If I recall correctly, Alan mentioned this problem at the workshop, and
the problem was that some of the PHY chips were faulty at one point. This
may be what's going on. Hopefully
Um, no, this is probably a different problem. You are getting these
errors while using SSH/SCP, right? The hardware problem with faulty
PHY manifests as one or more of the PHY LEDs flashing on/off (there
are three red ones next to the PHY chip). If your link is stable, then
I believe the ha
Hi Jason,
thank you for your reply. The SUN link was very descriptive.
Firstly, it appears the problem is still there with the kernel build you
suggested/ After a few megabytes, the connection closes telling me;
"Corrupted MAC on input".
But interestingly it seems to have solved another prob

There appears to be some issue with ssh on ROACH with large transfers.
It is definitely not a hardware problem as other network transfers
work fine. Both Andrew Martens and myself regularly transfer large
amounts of data (>1GB) using KATCP. This ssh bug has become a low
priority for us as w
Hi Jason,
Thank you again for your reply. I can use FTP or even write my own
little raw socket transfer routine, and it seems to work, I can
transfer a few gigabyte-size files.
However, at the end of this, the other problem kicks in; causing a
system crash. I believe this is a kernel proble
Marc Welz or David George built that kernel. They are the best people
to ask about this. I've cc'd them, though I'm not sure either would
have the config file from that release. It might be easiest to
checkout an older svn version.
Might I suggest that instead of recording data to a USB HDD

Hi all,
For reference I've attached a summary of our problems below, and a few
things I have attempted to do to isolate it. The short of it is that we
are unable to transfer large amounts of data across the ethernet
reliably regardless of;

--whether we are usb mount or nfs mo
As you say, NFS mounts work correctly which would indicate that the
network is operating as expected. WRT other errors, are you certain
that all reads/writes on FPGA are on 32-bit boundaries? Byte-sized and
16-bit reads are supposed to work, but we have found that for some
reason they somet
Also, make sure you're running newwer versions of uboot and the CPLD
image. Bus settings changed some months back and improved stability
significantly.
Uboot will report the versions, and I recommend:
U-Boot 2008.10-svn2226 (Aug 7 2009 - 16:06:44)

Monitor Revision: 8.3.1698

Hi Jason,
Thanks for your pointers; I am currently not actually using the FPGA.
Just focusing on being able to talk to the powerpc reliably at the moment.
The system does also crash when using NFS, but as I said and you noted;
it is more difficult to trace them directly back to EMACS related

Hi all.
I think it would be very cool if someone who knows could make a wiki page
to tell us what the suggested set of cpld/uboot/linux codes are, and if
the suggested versions are different for different purposes. There's
getting to be quite a few choices in the archive.

Hi Jason,
Just out of curiosity, did you get my last email? I noticed that your
reply was not to the last one I sent. In the last one I detailed some
tests and the results. It also showed the uboot and bootstrap config.
Anyway, it had some attachments and I am unsure how the list handled

Sorry, I meant that I will be back on the 16th.
