Setting up network in L4Linux - l4-hackers

20 Jan 2016

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.
