[ECOS] Configuration of static IP addresses

[ECOS] Configuration of static IP addresses

[Christian Plessl]

Hi Folks

I'd like to configure eCos TCP/IP networking with fixed IP addresses.
Could anybody please tell me, which configuration options in ecos.ecc I 
have to change.

I've tried this some time ago without any problem, but now I can't manage 
it anymore.. strange..

Search for CYGHWR_NET_DRIVER_ETH0_ADDRS_IP although you should remember to
make sure an ethernet card has been enabled in your configuration.

That was what I tried, but I get just the following error message:

C CYGHWR_NET_DRIVER_ETH0_SETUP, "requires" constraint not satisfied: 1 ==
CYGHWR_NET_DRIVER_ETH0_SETUP

  Unable to generate build tree, this configuration still contains
conflicts.
  Either resolve the conflicts or use --ignore-errors


I cannot figure out, how to resolve this conflict.

Did you actually enable CYGHWR_NET_DRIVER_ETH0_ADDRS i.e. user_value 1 ?
It's an option too.

There are three configuration options that implement the way the IP
address is determined: CYGHWR_NET_DRIVER_ETH0_MANUAL, BOOTP, and
ADDRS. The default is BOOTP. Only one of these can be enabled, so you
need to disable the default option BOOTP and then enable ADDRS.

If you look at CYGHWR_NET_DRIVER_ETH0_SETUP where the problem is
reported, you should see something like:

cdl_interface CYGHWR_NET_DRIVER_ETH0_SETUP {
    # Implemented by CYGHWR_NET_DRIVER_ETH0_MANUAL, active, disabled
    # Implemented by CYGHWR_NET_DRIVER_ETH0_BOOTP, active, enabled
    # Implemented by CYGHWR_NET_DRIVER_ETH0_ADDRS, active, disabled
    ...
}

This lists all the relevant configuration options.

Now it works.

I had to set all the following options

CYGHWR_NET_DRIVER_ETH0_ADDRS => user_value 1
CYGHWR_NET_DRIVER_ETH0_ADDRS_IP => user_value 192.168.1.50
CYGPKG_NET_DHCP =>  user_value 0
CYGHWR_NET_DRIVER_ETH0_BOOTP =>  user_value 0

Thanks for your help.

Chris

Purely FYI, you should have found that the latter two would have
automatically got set to 0 if you used "ecosconfig resolve".
