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

Sure 1.

No, I am using static IPs 3. No, Ubuntu 22 on Host PC 4. axi_ethernetlite_0: ethernet@40e00000 { compatible = "xlnx,axi-ethernetlite-3.0", "xlnx,xps-ethernetlite-1.00.a"; device_type = "network"; interrupt-names = "ip2intc_irpt"; interrupt-parent = <&microblaze_0_axi_intc>; interrupts = <2 0>; reg = <0x40e00000 0x10000>; xlnx,duplex = <0x1>; xlnx,include-global-buffers = <0x1>; xlnx,include-internal-loopback = <0x1>; xlnx,include-mdio = <0x1>; xlnx,rx-ping-pong = <0x1>; xlnx,s-axi-id-width = <0x1>; xlnx,select-xpm = <0x1>; xlnx,tx-ping-pong = <0x1>; xlnx,use-internal = <0x0>; axi_ethernetlite_0_mdio: mdio { #address-cells = <1>; #size-cells = <0>; }; };

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
