I get the following error when I configure my Mini2440 network settings for DHCP: ifup: don't seem to have all the variables for eth0/inet When I have a static configuration it works fine. Configuration example: auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp address 192.168.1.10 netmask 255.255.255.0 gateway 192.168.1.1 broadcast 192.168.1.255 What could cause this?
Run "ifup" with "strace". Maybe it will show you what "ifup" tries to get your interface up and running.
I had a look. Would you mind having a look please? Thank you

Juergen Beisert? davef? sincerely, # ifup eth0 run-parts: /etc/network/if-pre-up.d: No such file or directory eth0: link down udhcpc (v1.13.3) started udhcpc: exec /usr/share/udhcpc/default.script: No such file or directory Sending discover...

Ok, So I had to enable: PTXCONF_DHCP=y and enabled Install /etc/dhclient.conf in ptxdist menuconfig, Network Tools->DHCP Now it does not give that error anymore. Do not have DHCP here at the moment, will test tonight.
Hi bluscape; I changed distro and everything is working well except touchscreen calibration. Do you know any easy solution for calibration of touchscreen? Sincerely,
Just found a reason for such an error message: Missing MAC address
Hi Juergen, Does this require the MAC in bootloader config or somewhere else? Bootloader ip=none and all network related setting are disabled.
