Hi Kelvin,

Thanks for the valuable inforamation. Now we are able to enable "eth0" option in  configuration tool & able to set static IP address for application.
But still not able to ping the h/w from PC
pls find attached gdb o/p file.

We observed following things today.
If we power on the system,  before starting serial application for download we can ping the H/W from PC
but after establising the serial communication for application download ping stops......

what changes / initialisation parameters I have to set in my application program OR configuration settings to start ethernet support?
Pls guide us

Thanks in Advance

Follow the eth0 sections in your .ecc file. As I understand it, the 
"Requires" or "ActiveIf" sections will tell you what you have to do to 
make the eth0 option available.

Hi Kelvin,

Thanks for the information. Now I am able to compile project succesfully. But netowrk  (ping command) is still not working.

Condition is as follows:
I want to enable the network mannually. I do not have DHCP/BOOTP server. I have fixed Static IP address.
using Sh7729 H/W & Pachage = net i am able to build configuration succesfully. But in configration application "eth0", "eth1" settings are gray (Disabled). I want to enable network for eth0
Which option should I change to enable these settings?

Thanks in advance

Aniket

This is because you have upgraded to a newer version of GCC. Please see 
the following:

http://sources.redhat.com/ml/ecos-discuss/2004-02/msg00383.html 

Basically you have to move icmpstat to a source file, rather than 
declare it (without extern) in a header file. This has been fixed 
already - you can see the solution in CVS.

Kelvin.
