[ECOS] How to connect RedBoot via Telnet running application

["m mariga" <ma_ariga@yahoo.co.jp>]

Hello,

I'd like to connect to RedBoot via Telnet during target's running net 
application.
I tried to run nc_test_slave program as application and connect to RedBoot 
via Telnet from host's cygwin.
The result is below.

$ telnet 172.16.1.200 9000
Trying 172.16.1.200...
telnet: Unable to connect to remote host: Connection refused

I append application running serial consol log below.

I am certain that the next excerpt from Anthony J. Massa's book is related 
to the cause.

--from Anthony J. Massa's book
NOTE:When using the Ethernet port for RedBoot communication
and in your application, it is important to set up the IP
addresses properly. The system distinguishes the destination of
a packet using the IP address. If the IP address for RedBoot and
the application are the same, RedBoot will receive all incoming
Ethernet packets, not passing them on to the application for processing.
To avoid this situation, it is best to use a static IP
address in one image and a separate static or dynamic image in
the other image.

I only set one IP address in CYGHWR_NET_DRIVER_ETH0_ADDRS_IP option like 
below.
cdl_option CYGHWR_NET_DRIVER_ETH0_ADDRS_IP {
    default_value { "172.16.1.200" }
}

But I do not know how to set IP addresses separately.
Right now I disables BOOTP by option mainly because I do not know how to use 
it.
I would rather prefer the two static IPs without using BOOTP or DHCP.
How should I set static IP addresses between RedBoot and application without 
using BOOTP ?
I presumed that RedBoot's IP is setted by fconfig,but I could not rewrite 
Local IP address.
Whenever I tried to rewrite Local IP address,or Gateway IP address,it 
happened 'command abort' message like below.
I do not know what is wrong.Please help me.
Am I correct thinking if I rewite Local IP address by fconfig,I could set 
RedBoot IP address differently with application address ?

RedBoot> fconfig
scan_opts: first=1, argc=1
Run script at boot: true
Boot script:
Enter script, terminate with empty line
>>
Boot script timeout (1000ms resolution): 3
Use BOOTP for network configuration: false
Gateway IP address: 172.16.1.1
Local IP address: 172.16.1.100
** command abort - illegal memory access?
