Part Number: AM3351

hi,

we are using ti-processor-sdk-linux-am335x-evm-08.02.00.24

we are using am3351 sitara connected with Marvell 88e1512 even through phy is detecting it is not pinging both u-boot and kernel .

i am attaching u-boot prints:

=> mii info
PHY 0x00: OUI = 0x5043, Model = 0x1D, Rev = 0x01, 100baseT, FDX
=> mdio list
ethernet@4a100000:
0 - Marvell 88E151x <--> ethernet@4a100000
=> setenv ipaddr 192.168.1.15

=> setenv ipaddr 192.168.2.10
=> setenv gatewayip 192.168.2.1
=> setenv netmask 255.255.255.0
=> setenv serverip 192.168.2.5
=> setenv ethaddr 34:03:de:66:55:6b
=> ping 192.168.1.20
link up on port 0, speed 100, full duplex
Using ethernet@4a100000 device

ARP Retry count exceeded; starting again
ping failed; host 192.168.2.5 is not alive

in kernel auto-negotiation is done and we also verified with wireshark but no data is coming.

.

mounika

    Hi,

    There seems to be some odd things happening here. The wireshark capture is of a Dell machine asking for 192.168.2.5. If the Dell is not able to see the .5 address then the board will not be able to either. Is the MAC address showing up in the wireshark capture? If not then it s not.

    I would recommend the following as a test to prove that your board is sending packets.  Connect your board directly to the Dell machine and no other ports connected if possible. I am assuming that the wireshark application is running on the Dell machine. Just type these commands:

    setenv autoload n

    dhcp

    The dhcp command will start an ARP process, We want to be  seeing ARP packets with the MAC address of your board in the source address on ARP requests in the wireshark capture. Please attach the wireshark capture from this test.

    Best Regards,

    Schuyler
