hi, 

based on the nios2-linux-20100621.tar, I refer to the step by step in www,alterawiki,com / wiki /UClinuxDist   then I get a zImage booting successfully on the altera's 3c120 development board.    then I <ifconfig eth0 192.168.0.200 up> ,   then I can ping from my PC to the 3c120 board.   [zhengj@localhost uclinux-dist]$ ping 192.168.0.200 ping 192.168.0.200 (192.168.0.200) 56(84) bytes of data. 64 bytes from 192.168.0.200: icmp_seq=1 ttl=64 time=2.04 ms 64 bytes from 192.168.0.200: icmp_seq=2 ttl=64 time=0.637 ms 64 bytes from 192.168.0.200: icmp_seq=3 ttl=64 time=0.656 ms 64 bytes from 192.168.0.200: icmp_seq=4 ttl=64 time=0.676 ms 64 bytes from 192.168.0.200: icmp_seq=5 ttl=64 time=0.647 ms    So I think the driver for the altera TSE is working . but I fail to telnet from PC to 3c120 board: < [zhengj@localhost uclinux-dist]$ telnet 192.168.0.200 trying 192.168.0.200... telnet: connect to address 192.168.0.200: connection timed out >   I fail to ftp : < [zhengj@localhost uclinux-dist]$ ftp 192.168.0.200 ftp: connect: connection timed out ftp>  >      the output infomation for < netstat -a> is : < root:/>netstat -a # show network services active internet connections (servers and established) proto recv-q send-q local address foreign address state  tcp 0 0 <null>:ftp <null>:* listen  tcp 0 0 <null>:telnet <null>:* listen  active unix domain sockets (servers and established) proto refcnt flags type state i-node path >   the output infomation for <ifconfig> is : < root:/> ifconfig eth0 link encap:ethernet hwaddr 00:07:ed:11:12:12   inet addr:192.168.0.200 bcast:192.168.0.255 mask:255.255.255.0  up broadcast running multicast mtu:1500 metric:1  rx packets:985 errors:0 dropped:452 overruns:0 frame:0  tx packets:13 errors:0 dropped:0 overruns:0 carrier:0  collisions:0 txqueuelen:1000   rx bytes:124971 (122.0 kib) tx bytes:710 (710 b)  base address: 0x4000   lo link encap:local loopback   inet addr:127.0.0.1 mask:255.0.0.0  up loopback running mtu:16436 metric:1  rx packets:16 errors:0 dropped:0 overruns:0 frame:0  tx packets:16 errors:0 dropped:0 overruns:0 carrier:0  collisions:0 txqueuelen:0   rx bytes:1280 (1.2 kib) tx bytes:1280 (1.2 kib) >   anyone please tell me how to do with the problem?

I have run <./checout> under dir nios2-linux, I think this will git to update the system. 

 the following script is in the checkout file: for i in  binutils gcc3 linux-2.6 toolchain-build toolchain-mmu uclibc elf2flt  insight u-boot uclinux-dist do cd $i git checkout -f cd .. done

for alexdb2012, 

 sorry , I install quartus on win7, not on linux.  but I think it seems that the driver for your download cable is not installed successfully.

[Altera_Forum]

Thanks for ur reply sir,but i executed the nios2-download command its showing like this 

  alex@alex:~$ nios2-download -g ~/uClinux/distro/nios2-linux/uClinux-dist/images/zImage there is a problem with the quartus ii installation on your computer. please use `jtagconfig` for further diagnosis.    Kindly any help?  Thanks, Alex.

alexdb, please post your questions only once, and don't hijack other people's threads when your problem has nothing to do with the original one. You make the whole forum hard to read. 

fbc99, I don't use Linux but the mdio part is necessary for the driver to know what speed has been negotiated on the Ethernet link, so that the MAC is configured correctly. There could be some options in menuconfig to enable/disable the MDIO code. If you search for the sentence "mdio bus registered" in the driver source code you may find some information on what needs to be done.
