Re: [microblaze-uclinux] opb_ethernet HWaddr of 00:00:00:00:00:00

["Yeoh Chun Yeow" <yeohchunyeow@xxxxxxxxx>]

Hi Victor,

Please double check whether your DHCP server is up. Do you setup your own DHCP server?

You can try out various dhcp clients, such as dhclient, dhcpcd or udhcp client (Busybox).

Hi Kristoffer,

I am able to set the HWaddr now. Thank you.

But I cannot ping any other ip address, I am using a static IP address.

If I run dhcp client, I get this error message:
Dhcpcd[60]: timeout waiting for a valid DHCP server response

I am using petalinux-v0.20-rc3.

Rgds,
Victor Yeo

Hi Victor,

The Ethernet address is set by u-boot from the u-boot configuration. Are
you booting through u-boot? If not, the behaviour you described is
remedied by first issuing the command

# ifconfig eth0 down

and then configuring the address manually

# ifconfig eth0 hw ether 00:00:5e:00:fa:ce
