Problem in using PPP & Ethernet Interface, together, with TCP/IP

Hi,
It seems that it is must to add a loopback interface along with the Ethernet interface. After adding the loopback interface the code works fine without any problem.
Thanks & Regards,
Viral Shah

I'm putting together an embedded web server on an MPC55xxevb (MPC5554 Phytec) system. After I got the basics working I put the HTTP on NFS for ease of development. I started getting NFS timeouts whenever a browser tried to load the RTEMS .jpg file:
[/] # mongoose document_root /data/http listening_ports 80 stacksize 0xc000
Loading filesystem image...
Mongoose 3.0 started on port(s) [80], serving directory [/data/http]
[/] # NFS (proc 6) - RPC: Timed out
[/] # ls -l data/http/rtems_logo.jpg
-rw-rw-r-- 1 500 500 14586 Mar 6 2011 data/http/rtems_logo.jpg
[/] #
On a hunch I rebuilt with -O2 back on (I'd turned it off a while ago for debugging) and now it works fine.
This isn't a bug report, obviously, it's a "has anyone else seen this?" question. The ethernet driver is one I brought up, the smc91111, which I think had previously only been used on Sparc. I'm going to ignore the issue today unless it comes back with the optimization on.

Hi,
can you please add the loop back interface and try our test again? In RTEMS
4.9.4 you can add the loop back interface like this:
int rtems_bsdnet_loopattach(struct rtems_bsdnet_ifconfig *, int);
static struct rtems_bsdnet_ifconfig loopback_config = {
"lo0", /* name */
rtems_bsdnet_loopattach, /* attach function */
NULL, /* link to next interface */
"127.0.0.1", /* IP address */
"255.0.0.0", /* IP net mask */
};
Have a nice day!

Typically this is what Python does. On the RTEMS port a user creates a
single C file that references the required modules and they get linked
in. No code loading was needed.
You cannot use Python's build system. It is broken from cross-compiling.
Once built I found Python embedded well. Its libraries allowed me to
create powerful applications.

Nice. The more choice the better for RTEMS users.

Hi,
can you point me out any tutorial on how to write and execute an
application from the scratch for RTEMS.
I already checked the Application C user guide, it is a good reference,
but it doesn't
help me to understand how to compile the application (what compiler
should I use? is there any specific rule for the Makefile?)
Any suggestion is welcome.
Domenico

Hi
I have experienced the same problem.
My solution was really simple, since I started RTMES with qemu (on a
Fedora virtual machine)
with the command qemu -m 128 -boot a ...
I removed the "m" flag -> qemu -boot a ... and it worked :)
Hope this helps other users.

Hi All,
I am trying to build RTEMS 4.10 for m68k target. Below are the details of the tool chain
1) gcc-4.4.5.tar.bz2
2) binutils-2.20.1.tar.bz2 with patch binutils-2.20.1-rtems4.10-20100826.diff
3) newlib-1.18.0.tar.gz with patch newlib-1.18.0-rtems4.10-20110114.diff
I have configured the rtems with following options which works correctly.
../rtems-4.10.0/configure --target=m68k-rtems4.10 --disable-posix --disable-itron --enable-rtemsbsp=m5484FireEngine --prefix=/opt/rtems-4.10
When I do make all, I get error `Configuration_POSIX_API' undeclared (first use in this fun
ction). Has anyone faced similar problem? Can someone tell me what causes to give this error?
Please see the logs below..
