Hi Wei-Chung
Yes, the shipping versions of tcpborphserver do not allow multiple
versions of tgtap at the same time and are the cause of the errors you
describe (as outlined on the wiki page).
I recommend you install a new version from here:
http://casper.berkeley.edu/svn/trunk/roach/sw/binaries/tcpborphserver/tcpborphserver2
Then use the updated python script from the workshop tutorial, tut2:
http://casper.berkeley.edu/svn/trunk/ref_designs_tutorials/workshop_2009/roach_tut2_10GbE/
Note that there is a bug in the shipping versions of the ROACH's
kernel too, and I highly recommend you replace that with http://casper.berkeley.edu/svn/trunk/roach/sw/binaries/linux/uImage-20091006-mmcfix
and also update your uboot to http://casper.berkeley.edu/svn/trunk/roach/sw/binaries/uboot/20090811-uboot-nohack.bin
Note that the new uboot (mmcenv) has a problem with debug messages.
Don't use that one, use the "nohack" version.

Dear All,
I am new to ROACH platform and currently I'm trying to bring up the
ROACH 10GbE interface as the new ROACH 10GbE tutorial do.
http://casper.berkeley.edu/wiki/ROACH_10GbE_tutorial
But the python scripts does not seem to bring up the 10GbE interfaces
successfully. I also noticed that Jason had mentioned the two 10Gbe
interfaces can not work at the same time.
http://www.mail-archive.com/casper@lists.berkeley.edu/msg00760.html
So I tried to bring up one of the interface by using the KATCP command
and got the following error message:
?tap-start gbe0 00:01:02:03:04:05 10.0.0.20 60000
#log warn 1256639552073 tcpborphserver process\_id\_469\_exited
\_abnormally
!tap-start ok
It seems the interface can not be setup successfully.
So again I tried to use the tgtap way as below link
http://www.mail-archive.com/casper@lists.berkeley.edu/msg00712.html
But I got below message:
