[ECOS] network test problem on ipaq

[ECOS] network test problem on ipaq

[Weilong Li]

I try to run tcp_echo, tcp_source and tcp_sink
program on ipaq.

From linux host, I used serial port to connect
ipaq, then I used gdb to remotely run tcp_echo, after
tcp_echo is running, and I run tcp_source and 
tcp_sink, but I got "no route to host" message.
And I cannot ping ipaq.

While before I run tcp_echo, I can ping ipaq, and
tcp_source and tcp_sink can successfully run and
waiting for packets. But I cannot run tcp_echo
through gdb, it simply cannot load the program.

So it seems there are conflicts even I used
serial port to run tcp_echo, and used
ethernet interface to run tcp_sink and
tcp_source. Please help.

thanks,

Weilong

You cannot even load it? Do you get any output from GDB?

Re: [ECOS] network test problem on ipaq

[Weilong Li]

The ip adddress of ipaq is 192.168.1.20. After redboot
boots on ipaq, I issued tcp_source and tcp_sink
command
to target on my redhat host.

# ./ecos/packages/net/tcpip/current/tests/tcp_sink
192.168.1.20
Start TCP test - SINK mode to 192.168.1.20

At another terminal:
# ./ecos/packages/net/tcpip/current/tests/tcp_source
192.168.1.20
Start TCP test - SOURCE mode to 192.168.1.20

And I pinged 192.168.1.20, and I got response.

Then I issued gdb command on tcp_echo. This time it
can load, while immediately after I type "continue",
and tcp_echo is running, tcp_sink and tcp_source
will report "no route to 192.168.1.20", and
I cannot ping ipaq from linux host.
Here is the screen.

Here are two screens from tcp_sink and tcp_source.

192.168.1.20
Start TCP test - SOURCE mode to 192.168.1.20

Can't connect to target: No route to host

The problem I'm suspecious of is that: after tcp_echo
is running through serial port, the ipaq seems stuck
there and not responding to other connections (even
from ethernet card interface.)
But I don't know what is behind.

thanks,

We need more details.  What version of RedBoot?  Can you send
a listing of the output from GDB?

RE: [ECOS] network test problem on ipaq

[Weilong Li]

Hi, Gary, please look at the email I  posted later
after my original post, there are detailed 
description of the problem.

thanks a lot,

Firstly, are you making sure that tcp_echo is running _before_ starting
tcp_sink and tcp_source? Secondly when you talk about the IP address of the
ipaq, there are two to consider: RedBoot's and eCos's. Their addresses
should not be the same. The latter one is the relevant one for the net
test.

Re: [ECOS] network test problem on ipaq

[Weilong Li]

  I also tried running tcp_echo before, after
tcp_echo is running, I cannot ping ipaq, 
so tcp_source and tcp_sink will always 
return "no route to host" error message.
  The ip address of ipaq I'm talking about 
is assigned by running a dhcp server on linux host,
then upon redboot boots, it will detect the 
socket communication ethernet card, and then
assign the ip address. So in this sense,
I think the ip address is redboot's ip address.
I don't know how the ip address of ecos is assigned,
can you elaborate on this ? 

thank you so much,

The eCos network stack does not use redboot's ip address ( you can't have
two different network stacks processing the same data). The eCos stack's IP
address is set according to the CDL data, either also from BOOTP/DHCP, or
statically. Try setting it statically as that's safest. Look for the
component CYGHWR_NET_DRIVER_ETH0_SETUP_OPTIONS and the options within it.

Re: [ECOS] network test problem on ipaq

[Weilong Li]

Hi, Jonathan, I have another newbie question.
I have changed the configuration regarding 
CYGHWR_NET_DRIVER_ETH0_SETUP_OPTIONS, and
also give a static ip address for ecos,
and then ecosconfig resolve, ecosconfig tree,
and make.
My question is how to update the ecos version
that is already running on ipaq with the new 
ecos version.

thanks a lot,

eCos is linked with your application so relinking your application with the
eCos libraries and uploading that is sufficient.

Re: [ECOS] network test problem on ipaq

[Weilong Li]

Hi, I have tried both static ip and dhcp, still
I cannot get the network configuration of ecos
to work correctly. Is there any documentation
, or best of all, an example of network configuration
in the ecos.ecc, this would help a lot.

thanks,
