Hi Santhosh Kumar,

Some simple initial tips:

1. Make sure the cable is correctly connected to the right ethernet port on the board (there are several ports)

2. Make sure the host 192.168.36.136 is normally available, you may use a third host to ping to the 192.168.36.136.

3. Check Firewall settings on your PC.

4. Check if the PC can ping the board

5. Check the switch settings whether they are all in default position as the board quick start document.

You can refer to the below link. I hope it is helpful for you.

The u-boot of i.mx6q cannot ping the board itself

Hi Radhika,

I was able to resolve "ethernet@30be0000 Waiting for PHY auto negotiation to complete"  issue by setting the MAC address in uboot and now the uboot driver is able to detect the phy, but the ping is not working please find the below trace and advice how to proceed ahead

I have set the ipaddr to 192.168.36.15 and trying to ping the PC.

Note: The board is directly connected to PC instead of connecting to network switch and PC IP address is set to 192.168.36.136

> do you get ip from PC instead of router? if you connect your board and PC to the same router, can you ping pc and board each other?

[santhosh2]

Hi Joan,

Yes we can ping when host is directly connected to  board. This behaviour i have tested using I.MX8MM NXP EVK kit

[joanxie]

[santhosh2]

Yes I have Fixed it
