hi all,
I am trying to compile the correlator of tutorial 4 but i changed the adc
to the acd083000x1. I have an error in the Starting program map.
i went to gen_xps_files (line 636) and there is an error with the
system(['xps -nw -scr run_xps.tcl system.xmp']) command. I do not know
what this
Hi.
Not sure of your error, but signal 9 is a sigkill by the system. Did
someone kill your process or did you run completely out of memory?
Running out of memory is a common cause of a spontaneous signal 9.

I recently got a ROACH2 from digicom and I'm trying to upload a bof
file. My tcpborphserver does not support the KATCP command

a bof file but when I read a register something crashes. According to
the previous posts, I

If you netboot: copy tcpborphserver3 to nfs_root_directory/usr/local/sbin.
Tcpbporphserver3 will load automatically when the roach boots.
If you soloboot (boot the root file system stored in flash), which is the

very useful and didn't appear to be there already.

Hi All,
Using the latest 10 GbE yellow block, has anyone achieved a sustained
data rate of greater than 8 Gb/s?
Thanks,

Thanks Glenn... I am preparing a whole lot of documentation for the wiki.
Hope to have it up soon!

Hi, Rich,
We've sustained 9.9 Gpbs simultaneously from two 10 GbE ports (19.8 Gbps
aggregate) on a ROACH into a PC with two 10 GbE NICs without dropping any
packets. This was direct connect (i.e. no switch) and transmit only (i.e. no
packets were sent back to the ROACH).
Hope this helps,

Hi, John,
The benchmarking tests were done here by Christopher Schollar who was
visiting from the University of Cape Town. I'm not sure which library
version he used, but I can find out.
It was mostly just curiosity on my part, but are you using the same blocks
for your work?

Hi, John,
My current work is on ROACH2 and the 10_Gbe_v2 block is the only 10 GbE block
supported on ROACH2 so that's the one I'm currently designing with (but not yet
using myself). I'm not sure which block Christopher used in the packet
generator. His design ran on a ROACH so it could have
Hi Dave and others,
I was under the impression that ten_Gbe_v2 was suppose to support ROACH2
as well. At least, its mask supports parameters specific to ROACH2 (such as
choice between CX4, SFP+ and ports etc.). Rather, these options are
available in the mask only for ROACH2.
Is 10_Gbe_v2 part of
I think it's just a typo and ten_gbe_v2 == 10_gbe_v2

Sorry for my 10_Gbe_v2 typo. I meant ten_Gbe_v2. There is no 10_Gbe_v2

It would be good to add an optional Latency parameter to the Shared BRAM
block and allow the user to select 1 (current value that does not use the
BRAMs optional output register) or 2 (new value that does use the BRAM's
optional output register). I think this would help ROACH2
