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?
You need to add the <name.dtb> file to your entry in the modules.list. In your Lua configuration where you start L4Linux you need to add another Linux kernel cmdline parameter like
l4x_dtb=rom/<name.dtb>
Then L4Linux should find and use the device tree.
Matthias.

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.
