How to make network ports DHCP?

We have successfully got our ROM-5722 board working, but are having issues with the Ethernet ports. We are using only 100Mb, so only TX & RX pairs.

Uboot with DHCP command correctly gets a DHCP address 100% of the time, so potentially ethernet circuitry is wired correctly.

In AIM Linux 5.4.70-5722A1AIM30LIVA0386, I have seen DHCP address allocated and networking works fine BUT most of the time I get a 169.254.149.xx address (auto allocated ?) and obviously no network connection.

How do I configure Linux to use DHCP ?

Hi, The DHCP has been enable in the image.


It also can try the “udhcpc” command to request IP.
