I managed to get everything work using the 2017_R1 example design on ZC706 board, bu when I change 

the MAC and IP address of eth0, I met some problems!

I modified the /etc/network/interface file to as follows:


auto eth0

iface eth0 inet static

pre-up ifconfig eth0 hw ether AA:BB:CC:DD:EE:01






Then reboot the system, the boot process hangs about 1 minute, finally it enters the linux,

but the network don't work.

If comments ''pre-up ifconfig eth0 hw ether AA:BB:CC:DD:EE:01", the network works fine!


And I tried another approach:

Add ifconfig command lines at the end of  "/etc/init.d/rc.local " file as :


ifconfig eth0 down

ifconfig eth0 hw ether AA:BB:CC:DD:EE:01

ifconfig eth0 netmask

sleep 5

ifconfig eth0 up


Then reboot, the boot process work right, but when pinging,

the ping results show : the network connect about 8-10 seconds, then disconnect,

about 30-40 seconds, then it reconnect all the time.


Anyone can give some tips about this? Any help will be appreciated!
