lwip problem-ping not working /BF527

Hi.

We have a hardware with ethernet lan 8700i  with PHYADD = 1f and with full duplex. we changed Dev->phyadd = 0x1f and full duplex = true in liblan8700BF527

using following program. after run program shows link established. but ping and connect is not happening. in our hardware we are using BF527 processor.

Target is able to send ARP packets.We use the program below which works fine in adsp bf527 ez kit.

C:\Program Files\Analog Devices\VisualDSP 5.0\Blackfin\Examples\ADSP-BF527 EZ-KIT Lite\LAN\Host\FILESERVER

can u plz suggest us the problem why ping is not happening.We tried TCPIPTRACE,INETD programs also ,and ping fails but link is established.

We have reserved bank3 (LAST BANK)flash for FPGA.

Thanks...........

    What are the values you programmed and what are the values reflected in memory? Can you post screenshots of GUI and user_net_config_info in expression window? Maybe you should try this with a default LwIP template. Is there any reason to think that these variables reside in SDRAM and maybe that is corrupting the data? As a second step, if the new values in memory are consistent, you may program PC with similar values (typically just change IP address + 1) and PING to Blackfin.
