DE2 dev board ->ETH problem

Please try out the DE2_NET.sof and zImage_de2_net files attached in

http://nioswiki.jot.com/wikihome/operating...s/tryoutuclinux (http://nioswiki.jot.com/wikihome/operatingsystems/tryoutuclinux)

It has the dm9ks driver enabled so you play without any compilation.

The later sof files in DE2 packages (1.3-1.5) might have some problems in SDRAM. The above sof is from v1.1.

You may look at the boot message of DE2 in the page,

http://nioswiki.jot.com/wikihome/operating...ems/uclinuxdist (http://nioswiki.jot.com/wikihome/operatingsystems/uclinuxdist)

and watch for the probe of the chip,

<DM9KS> I/O: 80900090, VID: 90000a46

And you should try out the ifconfig and net services.

When you want to config the kernel, select only the dm9ks net driver.

[*] DM9000A with checksum offloading

Thank you hyppo, it works. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/biggrin.gif

At the boot message of DE2 i can see :

<DM9KS> I/O: 80900090, VID: 90000a46,

but if i do an ifconfig i just have the localhost,

no eth0 or something like that. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/blink.gif

Why ???

You told me : <div class='quotetop'>QUOTE </div>

But i don&#39;t see when it is in the kernel configuration. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/unsure.gif

What i have to do, to configure the eth as you show it on ethernet (http://nioswiki.jot.com/wikihome/operatingsystems/%c2%b5clinux/ethernet), ??? (cause i never config it before, and i don&#39;t know what to do http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif )

Thanks

Good Bye

did you run ifattach?

/bin/ifattach --addr 10.1.1.99 --mask 255.255.255.0 --net 10.1.1.0 --gw 10.1.1.11 --if eth0

of course you need to fill in the settings of your network.

Thank for your help nacide, but iI&#39;m sorry, the result of your command is

/bin/ifattach: Bad command or file name

Any ohter idea ??? please http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif

of course you need the ifattach exexutable in the /bin directory of your rootfs

You can copy ifattach from the examples of the microtronix port among with many other utilities. Make sure that you have set the permissions to executable.

You need to bring up eth0 first, before you can use ifconfig to list eth devs.

Either,

ifconfig eth0 192.168.1.10 # static ip

route add default gw 192.168.1.254 # gateway

Or, use dhcp client

ifconfig eth0 up

dhcpcd &

About the kernel config problem, which version of uClinux-dist and nios2 patches do you use?

You should disable SMC91 chip and select DM9000A with checksum offloading.

Check if you have this file, linux-2.6.x/drivers/net/dm9ks.c .

Hello,

Yes, your command works, i have the eth0 with a good configuration.

I use uClinux-dist-20070130 and the patch uClinux-dist-20070130-nios2-02.diff which is present here (http://nioswiki.jot.com/wikihome/operatingsystems/%c2%b5clinux/uclinuxdist/uclinux-dist-20070130-nios2-02.diff.gz?cachetime=1170915312300).

I haven&#39;t got the file dm9ks.c. Maybe it&#39;s the reason of my failure http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/mad.gif .

Can you send it to me ??? (and if you have the time, can you send me your ptf, or all the thing that i need to correctly compile uClinux ??? http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/rolleyes.gif )

Thanks for your help http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/biggrin.gif

Or you may not have the patches applied, you need a path to the patch file,

gunzip -c <path>/uClinux-dist-20070130-nios2-02.diff.gz | patch -p0

Hi,

I have applied the patch uClinux-dist-20070130-nios2-02.diff.gz, and now, i have the dm9ks.c in the in linux-2.6.x/drivers/net/, but it never ask me the things which are present at nioswiki.forum.com (http://nioswiki.jot.com/wikihome/operatingsystems/ethernet). http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/huh.gif

I never see this text ... so ... on the uClinux that i create, at the boot, i haven&#39;t "<DM9KS> I/O: 80900090, VID: 90000a46", and i must finish my project in 4 days http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif

All the other things are done, but this point is the final.

Please, Can you help me ??? http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/rolleyes.gif

I really need to build a µClunix image with my programs, and boot it on my DE2 board with an enabled ethernet.

Thanks.
