Hi Mohammad,

As feed back of my previous effort, i can tell you that i was able to bring IPsec to the LWIP stack and test it with manual configuration and it is work well .

Now i would like to test that in RPi , but actually I faild even to run the Demo example by using the release 14.08 of Genode. later, I tried with the release 13.11 and it is working smoothly.

Now i would like to test the network example ( libports/run/lwip.run) i tried to run it but i get

make[1]: Leaving directory `/home/mohammad/genode-13.11/build.rpi' cp: cannot stat `bin/nic_drv': No such file or directory

any one was able to run this test successfully before ? if not , any advices or suggestions to help me to do it .

Christian Helmuth and me have actually worked on the Rpi support over the just passed Hack'n'Hike weekend. We implemented the early in-kernel handling of USB SOF interrupts. bringing the CPU load caused by the USB driver to a reasonable level. We also tested networking (which is realized via networking-over-USB on the Rpi). You can find this line of work on the following branch:

https://github.com/nfeske/genode/commits/rpi_usb

You are right that networking on the Rpi was pretty much untested until now. With the branch above, however, demo.run, wm.run as well as lwip.run are known to work. So you may give it a try. Taking a closer look at the individual commits will give you a good indication about the kind of changes required to add Rpi support to an existing run script.

Cheers Norman
