help: ping is ok, but telnetd and ftpd doesn't work

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

if I download the zImage of www, alterawiki.com/wiki/ Try_out_without_compilation , telnetd will work. there is "altera tse mii bus: mdio bus registered" message when booting.

but when I download the zImage generated by myself, there is no "altera tse mii bus: mdio bus registered" message when booting.

So I'm looking to the driver code.

any help is appreciated&#65281;
