Dear community,

 

we are experiencing something as follow:

 

tthe system is trying to get the IP address from the router through dhcp during bootup

 

we got the following:

 

Sending discover...

PHY: 0:00 - Link is Up - 100/Full

Sending discover...

PHY: 0:00 - Link is Down

Sending discover...

PHY: 0:00 - Link is Up - 100/Full

Resetting PHY

No lease, failing

 

 

after that, we asked to eth0 to up and get IP, it works perfectly ( we can ping like 1 hr without any problem)

it just couldn't get the IP when bootup

In 50 pcs of our prototype, around 15pcs couldn't get the IP at bootup

 

Anyone can point me to some direction where to look at?

 

thanks

 

roy
