nuc980 networking support not work

[ATmega8]

I used nuc980_iot_defconfig configuration and added

CONFIG_CMD_PING=y
CONFIG_CMD_DHCP=y
CONFIG_NETDEVICES=y
CONFIG_NUC980_ETH=y
CONFIG_NUC980_EMAC0=y
CONFIG_NUC980_PHY_ADDR=0

added

ipaddr=192.168.0.100
ethaddr=10:20:30:40:50:60 

to env.txt

but,I try to execute

ping 192.168.0.1

in the command line。command line seems to stop at

=> ping 192.168.0.1
Using emac device

Is my configuration wrong?

10:20... is a multicast MAC address. Can you test with other setting? https://en.wikipedia.org/wiki/Multicast_address#Ethernet

I tried random MAC address but still not work.

Can't reproduce this issue. Here's my test result. Are you testing on IoT board? Or on other device?

=> ping 192.168.10.1
Using emac device
host 192.168.10.1 is alive

I tried to find out where the program was executed by adding logs. But after adding my logs, the network seems to be back to normal.Maybe a problem with my hardware design.
