[Ethernet not working on petalinux [Arty 35T board]]

[SOLVED]: Clock Frequency for Ethernet was not exact. Was set as 25.0234 instead of just 25.00 MHz.

2. No, I am using static IPs

3. No, Ubuntu 22 on Host PC

I included this description in the dts:

 

&axi_ethernetlite_0{

 local-mac-address = [00 0a 35 00 01 22];

 compatible = "xlnx,xps-ethernetlite-1.00.a";

 device_type = "network";

 phy-handle = <&phy0>;

 xlnx,has-mdio = <0x1>;

 interrupt-parent = <&microblaze_0_axi_intc>;

 xlnx,duplex = <0x1>;

 xlnx,include-internal-loopback = <0x1>;

 xlnx,rx-ping-pong = <0x1>;

 xlnx,tx-ping-pong = <0x1>;

 xlnx,use-internal = <0x0>;

 mdio {

   #address-cells = <1>;

   #size-cells = <0>;

   phy0: phy@1 {

     device_type = "ethernet-phy";

     reg = <1>;

   };

 };

};

 

The petalinux build it is ok as well as the flash to the board (running as INITRD)

 

 

However, i am not able to ping from my host PC (Ubuntu 22). I only get:

mypc@xxx:~$ ping 192.168.0.10

PING 192.168.0.10 (192.168.0.10) 56(84) bytes of data.

From 192.168.0.103 icmp_seq=1 Destination Host Unreachable

From 192.168.0.103 icmp_seq=2 Destination Host Unreachable

From 192.168.0.103 icmp_seq=3 Destination Host Unreachable

From 192.168.0.103 icmp_seq=4 Destination Host Unreachable

From 192.168.0.103 icmp_seq=5 Destination Host Unreachable

From 192.168.0.103 icmp_seq=6 Destination Host Unreachable

 

On the other hand, if i ping from arty board to host PC i get:

artyA7_peta:~$ ping 192.168.0.11

PING 192.168.0.11 (192.168.0.11): 56 data bytes

and have no response at all.

Using wireshark it seems like this:

 

 

Running ip neigh in the host PC I get:

mypc@xxx:~$ ip neigh

192.168.0.10 dev eno1 lladdr 00:0a:35:00:01:22 STALE

192.168.0.1 dev wlo1 lladdr 5c:a6:e6:ea:7f:01 REACHABLE

169.254.169.254 dev wlo1 FAILED

192.168.0.10 dev wlo1 FAILED

 

So my question would be what is left to do to have it running?

 

Thanks in advance
