正常进入uboot指令阶段，设置好addrip serverip，此时ping服务器发现报错FEC1 Waiting for PHY auto negotiation to complete......... TIMEOUT !。之前操作均是参考手册执行。
以下是uboot 环境参数打印

尝试ping 服务器ip发现：

1. => ping 192.168.10.227
   
2. FEC1 Waiting for PHY auto negotiation to complete......... TIMEOUT !
   
3. Using FEC1 device
   
4. ping failed; host 192.168.10.227 is not alive
   
5. => ping serverip
   
6. ping - send ICMP ECHO_REQUEST to network host
   
7. 
   
8. Usage:
   
9. ping pingAddress
   
10. => ping ${serverip}
    
11. FEC1 Waiting for PHY auto negotiation to complete......... TIMEOUT !
    
12. Using FEC1 device
    
13. ping failed; host 192.168.10.227 is not alive

麻烦尽快解决以下啊。很着急啊。

系统起来以后是否能ping通服务器，确保硬件上和物理连接上面没有问题。

好的 ，多谢提醒，我重新检查了一遍，并重新烧写后，尝试可以了，但是现在卡在TFTP下载下来后不知道如何固话到emmc中，记得需要emmc write的一步操作，但是文档中没有，求指导 一下啊。

1. tftp ${loadaddr} zImage
   
2. Using FEC0 device
   
3. TFTP from server 192.168.10.227; our IP address is 192.168.10.232
   
4. Filename 'zImage'.
   
5. Load address: 0x80800000
   
6. Loading: #################################################################
   
7.          #################################################################
   
8.          #################################################################
   
9.          #################################################################
   
10.          #################################################################
    
11.          #################################################################
    
12.          ###############################################
    
13.          2.3 MiB/s
    
14. done
    
15. Bytes transferred = 6412400 (61d870 hex)
    
16. => tftp ${fdt_addr} imx6ul-14x14-evk.dtb
    
17. Using FEC0 device
    
18. TFTP from server 192.168.10.227; our IP address is 192.168.10.232
    
19. Filename 'imx6ul-14x14-evk.dtb'.
    
20. Load address: 0x83000000
    
21. Loading: ###
    
22.          1.8 MiB/s
    
23. done
    
24. Bytes transferred = 38175 (951f hex)

复制代码

也就是这一步之后该如何将下载后的内容固话到emmc中呢？
