but I don't recall any details.

Hi all. We have turned one of our Roaches into a doorstop. The serial
port does not ever show the uboot prompt. All we did was update the cpld.
In fact, I don't know if it was working before we updated the cpld, but
it worked the last time it was turned on, to the best of my knowledge.

We're about to try that now! Putting a few tens of clocks of delay in the

Hi all. Has anyone seen any problems when using 4 10 GbE ports on a
single FPGA in the BEE2?
We're having some problems where borph access from the control FPGA seems
to lock up when we start up our designs. We've done some testing with
hacked up designs, and we can only make it lock up (so far)

Hi. Does anybody know the actual limit on packet size for the

size in each case?
We want to package up 8K (8192) bytes of data + a few words of framing,
I guess it's fair then. Windows makes ME very unhappy!

This is the ticket. I think that the xilinx web site logs you off before

Hi. We just finished getting an ibob up and running from the prom, and we
saw a few strange things that might be related:
1) We had to cycle the power to get the design to load into the FPGA, even
when we checked the right boxes. This is unusual, but not unheard of.
2) We couldn't even get it t

It turns out that the 10 GbE core *is* needed, at least for version 7.1.
The rest of the IP modules that are needed have been freed by Xili

OK. I'll try it and see.
