 I would like to load new application object to target using RedBoot via 
Telnet from host PC during target's application running.

I also like to use RedBoot' monitor functions like "dump".

Is it impossible ?
I got an impression from Anthony J. Massa's book that if setted two
 different IP addresses between RedBoot and application,I could connect to
 RedBoot via Telnet during application running. Am I mistaken ?

Once the eCos application takes over, the RedBoot command line can't be used.

If you connected to RedBoot using GDB in order to load and run your 
program you can interrupt it while it's running - that's because the eCos 
build will permit RedBoot to take over for the purposes of GDB debugging.

I think for what you want to do, using GDB will work best for you.

Once your application starts, RedBoot is GONE.  The only way
to return to it is to exit your application, typically by
resetting the hardware.

Hello,Gary,and everyone,

I am very sorry.
I dare your anger for my obstination,but I must confirm next point.

Am I right in getting you that even I use BOOTP or DHCP to get  dynamic IP 
address for application and assign other staic IP address for RedBoot,I 
could not connect to RedBoot via Telnet during application running ?

Hello,Gary,and everyone,

Thank you, Gary, I got it.
Although I think it is too bad not to be able to use RedBoot's monitor 
function like memory dump during application running.

By the way,I do not know why I can't rewrite Local IP address or Gateway IP 
address by fconfig.
Please suggest my mistakes.

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?

It is not possible.  As I said, once your application is running,
RedBoot is out of the picture.

That's a reference to the ability of RedBoot to provide GDB
services via the network.  The rest of RedBoot's functionality
is no longer available, once your application starts.

Once your application is started, RedBoot is no longer available.

Why are you trying to do this?

[ECOS] How to connect RedBoot via Telnet running application

[m mariga]

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 ?

scan_opts: first=1, argc=1

Enter script, terminate with empty line
