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...........

  • Hi Craig,

    Please find that this is just ethernet brinup problem in a target(Mentioned configuration).

    This is entirely different from what we are doing in tool support.

    • When the target is receiving from host,packets are getting lost .We found that receive_ok bit not getting set and packet length is less than 64 bytes.

    Can you please tell what could be reason.

    • Is there any sample code for testing ethernet without DMA?

    We already spent much effort on this ping issue.

    Thanks in advance
