OK6410A 开发板 (三) 2 u-boot-2018.09 ethernet 解析

• u-boot-2018.09(源码基于https://download.csdn.net/download/Golden_Chen/11998917) 现状

1. 检查当前局域网可用ip
$ nmap -sP 10.10.11.*
2. 设置 u-boot ip 相关变量
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 局域网主机
OK6410 # ping 10.10.11.57
Unknown command 'ping' - try 'help'
4.配置 CMD_PING , 再编译烧写,再设置 u-boot ip 相关变量
5.ping 局域网主机
OK6410 # ping 10.10.11.57
No ethernet found.
ping failed; host 10.10.11.57 is not alive

• 修改点

1.
在 board/samsung/smdk6410/smdk6410.c 中 添加
int board_eth_init(bd_t *bis)
{
    
    
	return   dm9000_initialize(bis);
}
2.
配置 CONFIG_NET_RANDOM_ETHADDR

• 网络配置好的状态

In:    serial
Out:   lcd
Err:   serial
dm9000
