RE: [ECOS] networking support for my eCos application

[C B <csb_80 at hotmail dot com>]

Gary,

I think I'm missing something here.  I checked out the latest from CVS without any issues but when I tried 'ecosconfig new eb9261 net' I got a bunch of warnings about version subdirectory 'XXX' does not have a CDL script and no valid version subdirectories and finally and error 'Unknown target eb9261'  (out is included below).
 
I tried configuring things with configtool and that was even more confusing.  I tried building a template based on an ARM eval board (PID) but it wouldn't let me add any packages to the template (e.g. AT91 ethernet driver) nor was there any obvious way to create a new template.  The error I got when trying to add a package was 'add and remove hardware packages by selecting a new hardware template'.
 
I also notice that trying to create a new platform with configtool provides a dialog box with several fields but regardless of what I fill in the ok button is never enabled.
 
I was just hoping to be able to create an eCos configuration for an ARM 9 based evaluation board but I seem to be missing something fundamental in how these things are setup.  Is there any documentation that takes a new user through the process?
 
Thanks,
Chris

The eCos configuration I have appears to have the networking package included and yet when I attempt to link my application against the eCos libs I get several 'undefined reference' type errors.
