LS1028A网络问题-YT8614+YT8521
按照V2.3的底板单独做的底板，现在系统可以正常启动，但是网络设备找不到，不知道什么原因。麻烦大侠给看看！1、执行ifconfig后，只显示eno2和lo
eno2: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>mtu 1532

2、按照手册，对eno0执行操作
root@forlinx:~# sudo ifconfig eth0 192.168.1.3
SIOCSIFADDR: No such device
eth0: ERROR while getting inte**ce flags: No such device
root@forlinx:~# I2fwd -c 0xf -n 1 -- -p 0xc -q 1 --no-mac-uodating
-bash: I2fwd: command not found
root@forlinx:~# cat /etc/network/inte**ces.d/eno0
auto eno0
iface eno0 inet static

root@forlinx:~# ip addr flush dev eno0
root@forlinx:~# systemctl restart networking.service
[ 1571.685437] net eno0: could not attach to PHY
Job for networking.service failed because the control process exited with error code.

3、根据1和2的打印信息，eno0的phy没有正常工作，我检查电路后，我的底板与v2.3的开发板硬件配置一样，无法确定是哪里出问题
PHY的解复位信号正常吗？{:2_39:}
