    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...........

        I had a similar issue with the bf526.  The problem turned out to be that the library lan files configured the PHY for RMII mode, but the hardware was configured for MII mode.  You might try checking the RMII bit in the EMAC_OPMODE register.  I was able to get around the problem by simply clearing the RMII bit before starting the IP stack.
