Hey Genodians,

I am facing a problem with the Server/Client Application.
But first a short summary, what happend:
With the help from Johannes I am able to use Genode on the ZedBoard.
So the hello_tutorial is working fine and after that I am now trying to build my own Server/Client Application.

Here is the output from the boot up:

Genode 15.05

My assumption on what is going wrong is the following:
The server and the client needs to access the jitterentropy node at /dev/random and needs to write in the /tmp folder.
Here is the part of the run file:
set config {
<config verbose="yes">

            <service name="ROM"/>

                    <vfs>
                        <dir name="dev">

                        </dir>
                        <dir name="tmp">
                            <ram/>
                        </dir>
                    </vfs>
                </libc>
            </config>
        </start>
</config>}
I have no initramfs and linux kernel included which could provide the path to the folders.
So how do I provide the server and client to access the file/folder?
Can I use the server/ram_fs or should I use the Noux Runtime Environment?
Or is it something else?

Thank you in advance.
