Re: [seL4] Network lwip for imx6

hi, Chris.Guikenma, I follow what you told, but when I run the make command, it report error: error: invalid application of 'sizeof' to incomplete type 'struct eth_plat_config' struct eth_plat_config *config = (struct eth_plat_config *)malloc(sizeof(struct eth_plat_config)); That means the struct of eth_plat_config not defined, so I grep to search this struct, find nothing. Could you tell me where to find this file containing this struct? Chris Guikema 于2018年8月10日周五 上午2:06写道：

Xuguo,

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 yourself.

$ repo init -u https://github.com/dornerworks/dw-camkes-manifests -m http_server.xml

$ repo sync

You’ll need to go to the FileSystem component directory and run the makefs python script.

$ python apps/camkes_http/components/FileSystem/makefs.py

$ make http_server_defconfig

$ make

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,

Xuguo,

lwip on IMX6 is already available on seL4 (I have been using it in my project).

Look at the seL4/util_libs repository. There you can find the ethernet driver and the lwip.

Make sure to use the latest version (from master) that contains important fixes to the driver.

Regards,

Fabrizio

Hi,

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.

Best regards

from Xuguo Wang
