OK6410A development board (three) 2 u-boot-2018.09 ethernet analysis

u-boot-2018.09 (source code based on https://download.csdn.net/download/Golden_Chen/11998917) Current status

1. Check the available IP addresses in the current LAN

$ nmap -sP 10.10.11.*

2. Set u-boot ip related variables

setenv gatewayip 10.10.11.254

setenv ipaddr 10.10.11.120

setenv serverip 10.10.11.57

setenv netmask 255.255.255.0

3. Ping LAN host

OK6410 # ping 10.10.11.57

Unknown command 'ping' - try 'help'

4. Configure CMD_PING, compile and burn, and then set u-boot ip related variables

5. Ping LAN host

OK6410 # ping 10.10.11.57

No ethernet found.

ping failed; host 10.10.11.57 is not alive
