Regression tests are a set of tests that exercise the functionality
of the released gateware and software. The following are the initial
tests that need to be followed :
1.Go to : Systems -> Administration -> Server Settings -> Services and stop all the processes (except the process network) that are running (time consuming but has to be done). I had once faced a problem of not being able to open the Systems due to insufficient rights (dunno how that happened as I was the only user on the computer). For that, you can log into the root and type : system-config-services.
2. IPv6 needs to be disabled. This can be done as follows :
a. Type : /sbin/chkconfig ip6tables off
b. Type : gedit /etc/modprobe.conf and add the lines :
alias ipv6 off
alias net-pf-10 off
c. Edit network file using the command : gedit /etc/sysconfig/network and make the sure the following line is there : NETWORKING_IPV6=no
Regression Tests
1. Connect 'eth1' to 'nf2c0' and 'eth2' to 'nf2c1'.
2. Connect 'nf2c2' to 'nf2c3' (Leaving these ports unconnected causes errors in the regression tests).
3. Pull up all the interfaces :
ifconfig eth1 up
ifconfig eth2 up
ifconfig nf2c0 up
ifconfig nf2c1 up
ifconfig nf2c2 up
ifconfig nf2c3 up
And assign an IP address of 0.0.0.0 to all of them. This is done to remove the IPv4 address for each interface.
ifconfig eth1 0.0.0.0
ifconfig eth2 0.0.0.0
ifconfig nf2c0 0.0.0.0
ifconfig nf2c1 0.0.0.0
ifconfig nf2c2 0.0.0.0
ifconfig nf2c3 0.0.0.0
Now reprogram the CPCI using : /usr/local/sbin/cpci_reprogram.pl -all
Write the bitfile onto the NetFPGA using : nf_download ~/netfpga/bitfiles/reference_router.bit
Now start the regression tests using : ~/netfpga/bin/nf_regress_test.pl

hey do you know how to run this test with the release 3.0?
ReplyDeletethe same commands shud work..
DeleteHi,
ReplyDeleteI have this error coming
can’t locate NF/Base.pm in @INC (@INC contains: /usr/lib/perl5……………….) at /root/netfpga/bin/nf_regress_test.pl line 3.
BEGIN failed — compilation aborted at /root/netfpga/bin/nf_regress_test.pl line 3.
i rmmbr i had faced this problem but i don’t rmmbr how i got arnd it.. did u disable all the services under Administration?
Deleteim facing the problem that while running the command ~/netfpga/bin/nf_regress_test.pl –project reference_router.
ReplyDeleteI get an error:
nf_regress_test.pl: Cannot locate regression test file ‘/root/netfpga/projects/reference_router/regress/tests.txt’ for project ‘reference_router’
I searched the internet but they say that this file is not available in the v.3.0 package. Now tell me what should i do?
i dont think the version of the package makes any difference because i ran the same tests for v3.0 and didn’t have any problems.. just make sure that you stop all the services under Administration.. that was one thing that created a lot of problems for me..
DeleteHi Hari.
ReplyDeleteI have only eth0, because I have only one network card with one port RJ-45.
What I can do? Can I connect ‘eth0′ to ‘nf2c0′ and nf2c1 to another PC ?
u will need 2 ports to complete the regression tests.. but then regression tests are useful just to confirm whether the application is working fine or not.. u can skip them but the problem would b that you won’t know what the errors are.. i suggest you use a network card with 2 ethernet ports.. i dunno if u can connect nf2c1 to another pc because i have never tried it.. you can try it.. if it works out then well and good..
DeleteHi pharic, I got another network card (NIC), now I have eth0 and eth1, but when i did regression tests output this:

Do you know this error?
hey.. i rmmbr getting a similar problem but dont rmmbr how i got around it.. try googling the error.. might be helpful..
DeleteI have a same problem, and googling won't help because netfga forum is off. You still don't know how to fix this?
Deletei m sry XXXXXX but what problem do u have? one eth port or cannot locate regression test file?
Deletecannot locate regression test file:(
Deletefirst chk manually if the file is actually located in netfpga/bin directory.. if it is then there's a possibility tht there's some prob with the installation.. also make sure all processes under services are closed..
DeleteThere is not such file... I have progblem during installation of netfpga base package 2.1.1 (I already told you about netfpga kernel problem) so I removed that packet and installed new using yum install netfpga-base (v 3.0.1). Could that be problem? Don't know what to do know... To reinstall OS and start from beginning? And if I do that what packet to install 3.0.1 or 2.1.1. I want to use netfpga as reference router...
Deleterun : yum install netfpga-kernel - and tell me wht output u get..
DeleteI am home now so netfpga board isn't with me. I will tell u that tomorrow. Can u aswer me a last question about choosing 3.0.1 or 2.1.1 version for reference router until then? Could I use 3.0.1? Maybe than I won't have problem with netfpga kernel installation?
Deleteits always better to go with the recommended version and fr reference router it is 2.1.1.. don't go with reinstallation until u r sure thts the only thing u can do.. tell me the output with tht command tomorrow and let's see if we can get it running..
DeleteHi :) I removed netfpga base package today, and installed netfpga-base-2.1.1 and netfpga-kernel-2.1.1 and solved problem with locating regression test. Now I have new one ... Some tests failed. At first it reported problem that I don't have eth2 interface (I had eth0 and eth1). I deleted ifcfg-eth0 file and copied its contents in ifcfg-eth1, also copied contents of eth1 (before) in new file ifcfg-eth2 that I created manually. I don't know is this causing problems? Also I failed to assign 0.0.0.0 Ip adresses to interfaces, I typed comands from your blog but ifcfg command shows me that all interfaces have other adresses and get it by dhcp. Is this problem? Driver tests and some scone test gone well and than some problem with dijkstra routing problem, also I got messages about missing ARP request/reply pairs, after that more failed tests.
Deleterenaming et0 and eth1 as eth1 and eth2 doesn't solve the problems.. never mess with them.. :D the regression test behaviour can be very erratic.. was the board programmed successfully with the bitfile?

I have a net card with only eth0 interface, dunno if this an issue.
if u have only 1 ethernet port then u cant run these tests.. u need to insert an ethernet card with a dual port..

we are getting this error .how to recover from this problem.we have only one port in our pc.we completed self test successfully.we have connected nfc0 to eth0..to connect nfc1 should we require another pc with a same os or different os is possible?
u cannot use another pc.. u shud insert an additional ethernet card on ur pc..

i dunno abt this.. mayb u need to turn off some process under services..
Deletedo you knw where i can find the details abt these tests , like for proper debuggin .. , just asking , i am still stuck with these 2 errors : \ , getting really frustrating
Deletetry netfpga forum..
Deletehave you ever tried configuring switches?
ReplyDeletenope.. my project was for a duration of 2 months n i cudnt do much..
DeleteHi;)
ReplyDeleteWhen I load reference_router bitfile should I use ~/netfpga/bin/nf_regress_test.pl command or ~/netfpga/bin/nf_regress_test.pl --project reference_router. I ask u this because when I use first command every test is passed except one for reference_switch.... Now I am not sure am I doing all well. Should I load another bitfile to test reference_switch?
hey.. when u run ~/netfpga/bin/nf_regress_test.pl --project reference_router the regression tests specific to the reference router are run.. so u shud b fyn..
DeleteYes but what if I want to run NETFPGA like reference switch? After loading reference_switch bitfile regression test for it fails... That's only regression test that failed... It's weird. How could I know is this bitfile ok? I installed Netfga on two PCs, and this test fails on both of them. There are some errors with registers...
Deletewhat exactly are you trying to implement? reference router or switch?
Deleteif u downloaded the bitfile from the project then it will be defintely ok because it would obviously be tested before they put it up.. i dunno y it be failing.. maybe some process under services might be interfering..
I am trying to implement reference switch. I've turned off all services except networking, but regression test still fails. It can't find registers that regression test is looking for. Realy don't know what is a problem. I have used netfpga base packet version 2.1.1. Maybe I should use some older version?
Deleteyou could try a different version but its best to use the recommended version.. just try running after disabling networking service too..
Delete
