wahen i flash my zimage on flash memory , i can't use telnet

I have the same problem,

I write sof in EPCS and program in CFI

--- Quote Start ---

sof2flash --epcs --input=<chemin>/irp.sof --output=fpga_sof.flash

elf2flash --base=0x02800000 --end=0x02FFFFFF --reset=0x02800000 --input=zImage --output=uc_flash.flash --boot=<chemin>/Altera/nios2eds/components/altera_nios2/boot_loader_cfi.srec

nios2-flash-programmer --epcs --base=0x03001800 fpga_sof.flash

nios2-flash-programmer --base=0x02800000 uc_flash.flash

uc_flash.flash = 6MBytes, so i changed Processor type and features--> Link address offset for booting from 0x00500000 to 0x01555555 (2/3 of my 32M sdram)

I also changed rc file

hostname uClinux

mount -t proc proc /proc -o noexec,nosuid,nodev

mount -t sysfs sysfs /sys -o noexec,nosuid,nodev

mount -t devpts devpts /dev/pts -o noexec,nosuid

mount -t usbfs none /proc/bus/usb

mkdir /var/tmp

mkdir /var/log

mkdir /var/run

mkdir /var/lock

mkdir /var/empty

ifconfig lo 127.0.0.1

route add -net 127.0.0.0 netmask 255.0.0.0 lo# dhcpcd -p -a eth0 &

cat /etc/motd

mknoddev

ifconfig eth0 192.168.10.170

inetd&

After reboot, ping 192.168.10.170 work but not telnet

(I disabled the JTAG UART and i have 2 uart in sopc used for my application)

Thanks for help
