Greetings,
I am trying to run the image provided on the page:
http://www.openflow.org/wk/index.php/OpenFlow_AP_with_PC_Engine
Our lab has bought the same hardware as suggested by the tutorial. However, we
are using 4GB Kingston compact flash drives instead of the 2GB one. After
flashing the SwanWifi.img image on the CF card and trying to boot from it, I
get the infamous GRUB Error 17 during bootloading.
I suspected whether the fact that I'm using 4GB CF card instead of 2GB makes a
big difference. I also suspected whether the filesystem partitions has been
properly installed or the disk properly formatted. When I use "fdisk -l" to
peek into the content of the CF (through another PC with RHEL), I see four
drive partitions, with a /boot/grub directory present on two of them. All the
partitions types are "Linux". I tried playing around with the menu.lst and the
device.map files but the error persists.
Also, is there any former steps that I have to do to flash the SwanWifi image
into the CF card? I just assumed it was a regular image and used 'gunzip' and
'dd' commands to flash it. The tutorial site already assumes that the image is
properly flashed on the CF card, which in this case I believe has failed.
Did anyone encounter similar issues before or have any good suggestions?
Thank you in advance for your support,
Heming Wen

hi,
I am new to using NETFPGA and I have a few queries. I have installed a
NETFPGA card and also compiled the OPENFLOW using --enable-hw-lib. I am
able to ping two machine connected to this NETFPGA card and corresponding
flows also in the flow table using the dpctl command.
I wanted to explore the internal functionality such as how the flow
extraction is done, how the flow tables are populated. In short i would
like to know which parts of openflow are handled by the hardware and which
parts of it are handled by the software. I wanted to see what are the
openflow stages a packet passes through when is being received on a port
to sending to an output port. Is there a way to profile it or how do i
begin looking at some monitoring steps.

Hi,
Thank you for your interest.
We have a forum for NetFPGA users and you can find OpenFlow design section in
it.
It would be better place to ask NetFPGA related questions, and we would be
happy to answer to them there.
http://netfpga.org/forums/
Thank you,
Tatsuya
