Dear Mattias,
Thanks for helping out. But I still don't get where should I add the .dtb compiled file? and how would I manage to access it through L4Linux?

Hi,
are you using a device tree yet? In order for the driver matching to work in (L4)Linux somebody must tell Linux about the available devices. On ARM this can be done by either declaring a platform device statically or by using a device tree. So you have to enable "Flattened device tree support" in L4Linux and provide a simple device tree. See arch/l4/boot/dts/simple.dts for an example. And do not forget to compile the *.dts into a *.dtb file using 'dtc'. The name of the device tree file is provided on L4Linux' cmdline using "l4x_dtb=<name>".
Matthias.

However once I enter the console, ifconfig command displays no up interfaces. /proc/net/dev file indicates eth0 and lo available and I can run "*ifconfig eth0 up*" successfully. I configure a static IP using ip command but can't get any connection to my host machine. Also, adding *ip=dhcp* to the l4lx-net.cfg file in the start configuration of L4Linux fails with:
l4linux | Waiting up to 110 more seconds for network. ... l4linux | Sending DHCP requests ...... timed out! l4linux | IP-Config: Retrying forever (NFS root)...
I hope you can help me with that. Thanks in advance: Best Regards, Nourhan
