[ECOS] Permissions and Network

[Stuart Park <Stuart dot Park at sli-institute dot ac dot uk>]

Hi,

Hope someone can help, being stuck on this for a while.

Initially started working on eCos using the version 1.3 (current) 
repository,then downloaded the latest (v2) repository and changed the 
repository.  Problem is with I try to built eCos, etc, I get the 
following error.  I noticed this came up before and someone mentioned, 
switching the entries listed under 'mount' and change the to 'textmode'. 
I have done this and also made sure the permissions are correct, but 
still given errors, this is what I see.

The reason I wish to use the lastest repository, is because my project 
is interested in the network stack.  When I have been running the basic1 
application with the ecos library (setup up with new_net) linked in, 
using gdb, I have been trying to follow the program through to see how 
packets are sent from say the ip_output function.  As I am interested in 
the interface between the IP layer and the network interface device.

Problem is I struggling to see what happens (does it even go through the 
ip_output function), initially I set up the ecos build to use dhcp to 
gain an IP address, but this didnt seem to be recieving an address.  I 
then allocated an IP address statically and set up the other various 
components such as the gateway address, which am pretty sure should 
work.  However with both setup I am unable to find out if the IP address 
has been setup correctly, I can see all the various initialisation but 
not packet being sent out.

I am currently running redboot on a i386 target that has been given a 
static address of 127.168.112.210, where as ecos has been given a static 
IP address of 192.168.112.204, and using an Intel 82559 Ethernet card 
which is supported.  Debugging the target using a remote machine over com1.

Lastly I tried to build the tests as given in the eCos book, but for 
some reason or other these are also ending in error, not sure what the 
problem is, the output below is what I see.

Thanks for time, hope that makes some sort of sense.
