To add on, DornerWorks has also created an example http-server application that uses lwIP
and the Ethernet drivers to host an http-server on an imx6.
It’s on an older version of seL4 (7.0.0), but you can download it and try it out for
$ repo init -u https://github.com/dornerworks/dw-camkes-manifests
$ repo sync
You’ll need to go to the FileSystem component directory and run the makefs python
$ python apps/camkes_http/components/FileSystem/makefs.py
$ make http_server_defconfig
There is a readme document in the camkes_http application that overviews exactly how the
system is setup, and how the Ethdriver and Router components work.
In order to make an echo server, you would just need to create an interface to echo the
messages back and forth.
Let me know if you have any other questions,

I am a student fron Nanjing university, a fresh man of microkernel, specially,
know very little about the seL4.
Recently I accept a chellange about porting the lwip to sel4, on arch of imx6,
does any one could give me a clue?
I found the source of camkes does have this code, could I do something to port,
to make the lwip work? What my aim is make a tcp echo server.
Thank you for all of you help.
