[LS1046] Ethernet Rx not work after link reconnection

jhkim2 — Fri, 21 Mar 2025 08:19:04 GMT

Hi,

Ethernet of my board with LS1046 does not work after link reconnection.

(driver is fsl_dpa, and flexbuild_lsdk2108 is used, initramfs is used (not full ubuntu))

After cable plugged out and plugged in, link state is on (/sys/class/net/fm1-mac5/carrier = 1), but ping test fails.

I tested with "ifconfig fm1-mac5 down" and "ifconfig fm1-mac5 up", dmesg printed "ADDRCONF(NETDEV_CHANGE): fm1-mac5: link becomes ready", but ping test stil failed.

The packet statitics showed that Tx packet count increases, but Rx packet remains after ping.

Please give me an advice to slove this problem.

Regards,

J.Hwan Kim

Pls configure the static IP for both PC and LS1 board.

For PC, configure IP address to 192.168.0.1, netmask is 255.255.255.0
For LS1 board, configure IP address to 192.168.0.2, netmask is 255.255.255.0

Then connect LS1 board and your PC directly.

Then ping LS1 board on your PC.

Then check whether the RX counters increased on the target board.
