[ECOS] connecting a wi-fi lan card to a IXDP425 processor using the PCI slot

[ECOS] connecting a wi-fi lan card to a IXDP425 processor using the PCI slot

[Rohit Agarwal]

Hello,

I am very new to IXDP425 and eCos. As a part of my college project, I
am supposed to connect a wi-fi lan card to a IXDP425 processor using
the PCI slot.

However I have identified some issues that need to be addressed first.

1. I have realised that the TCP/IP stack in eCos is a port of the
FreeBSD stack. So, I will have to use FreeBSD wlan drivers instead of
linux drivers, which I earlier had in my mind.

2. Also, since 802.11 has its own protocol stack which goes between
the TCP/IP and the hardware driver, I will need to port this stack
also.

3. Since eCos's port of the FreeBSD stack is quite old, I will also
need to update the TCP/IP port.

Being quite new at these things, I am not able to figure out how to proceed. 

Please give me some suggestions or references from where I can get
some information which might help me.

Any help would be highly appreciated.

Thanking you in advance.

ROHIT

You might want to evaluate if this project is possible given your
experiance and available time. To me it sounds like a lot of work and
it's not going to be easy.

Anyway:

The FreeBSD sources can be downloaded from

Im sure with a bit of googling you will find more....

I responded to your post ( 10 Jul 2005 )
  " ecos on ixdp425 to simulate a GSM network "
where you ask the same question. Did you read the the
manual? Can you find a prism card ? 

you said you are very new to eCos, very new to IXP425,
new to 802.11, presumably new to TCP/IP stacks. I
agree with Andrew ...

Tell your supervisor you screwed up and negotiate a
penalty for switching projects. That is what school is
all about. You learnt a valuable lesson... you signed
a contract before doing the research.

ROFL

The problem is, few students are brave enough to admit they have
screwed up and just soldier on, resulting in either poor marks or even
failing.

Just use a 10baseT<->802.11 bridge.  The Linksys WET11 is about
$60, and they're trivial to set up and completely transparent
to the the attached device.

Write up you've found out about what it will take to do what
you're tasked to do.  Estimate how long it will take, and
propose ways to reduce the scope.  Like using an existing eCos
Ethernet driver and a 10baseT/802.11b gateway.

Re: [ECOS] connecting a wi-fi lan card to a IXDP425 processor using the PCI slot

[Rohit Agarwal]

I thought that the discussion list is meant for discussing and solving
problems (helping people) and not for discouraging them.

I appreciate your view point that I am very unexperienced to do the
level of work I am supposed to do. But all this was undecided when i
took up my project. I have come to the mailing list to solve my
problem.

The situation is such that I cannot backout from the project, even if
I want to (which I surely do). Being an IITian (have u heard of the
IIT's of india?), i am expected to put in a lot of hard work, and do
things which are not expected out of me.

The end result is that, 
1.if u decide to criticise me or to decrease my level of motivation,
then i'll have to look for some other way, because unfortunately
theres no exit to the project,
2. if u decide to help me, ill finally finish it up, though ill put in
a lot of effort, but finally ill have some result, and then with the
amount of experience in my hand, I will soon specialise in hardware.
Then maybe, who know, I might help you one day.

Decision is yours, problem is mine

Sorry for being rude

OK. If you really want to do this, i suggest you get hold of the books :

TCP/IP Illustrated, Volume 1, The Protocols, W. Richard Stevens - ISBN
0-201-63346-9 TCP/IP Illustrated, Volume 2, The Implementation, Gary
R. Wright, W. Richard Stevens - ISBN 0-201-63354-X

These two books are really good at explaining TCP/IP and the
implementation in BSD systems. To get this working you are going to
have to get deeply involved with the insides of TCP/IP and being able
to debug TCP/IP when you have bugs in your port.

I also suggest you get hold of another desktop machine and install
FreeBSD and make 802.11 networking work. You want to be able to
compile the kernel from sources and be able to debug them. You will be
using this as a reference platform. You can compare how things work on
this platform compared to what happens when you have bugs in your port
on eCos.

I also suggest you put your target hardware away for the moment and
use the synthetic version of ecos running on top of linux. You will
find that platform much easier to use and debug. Get the networking
working properly with synth, make sure you can run all the network
tests etc.

Gary Thomas can probably give you the clean FreeBSD sources he started
his port from. Diff'ing between those clean sources and the current
eCos sources will give you can idea what had to be changed to get the
FreeBSSD stack into eCos. You will need similar changes in your new
port. Applying the diff will get you some way in the right direction,
but i expect there will be conflicts you need to fix. Your aim is to
get the existing network tests working with the new TCP/IP stack. You
can probably forget about 802.11 for the moment. You can come back to
that once TCP/IP is working over ethernet.

That should be enought to keep you busy for a while.

Thanks a lot. This will surely encourage me to try do sthg, rather
than sitting idle. Even if I fail, ill be proud of the fact that
atleast i tried, because I believe that path to success is more
important than success itself.

Thanks a lot for taking interest in my problem.

I read the manual that u had suggested, but being an inexperienced
person, I cudnt make out much.

Can u in any way possible help me more?
