Hi All,
I have sent the patches for building lwIP from RSB. First patch
contains changes for RTEMS Resource Builder. The second patch is RTEMS
specific changes that will be applied to lwIP base.This patch contains
only lwIP sources. I will be sending another patch for the driver to
be used with lwIP. The application can then link to both of the
libararies (lwip & driver).
Has the LWIP patch been submitted upstream to the LWIP maintainers?
And where do drivers come from? From what I have seen, LWIP seems
to not have a unified base of device drivers. Would this just be to
build the basic stack and then it is the users responsibility to
find and compile a driver?
Also, what from these comes from our work? Sorry that I'm a little bit
confused and arrived late to the
subject. BTW, there is still work to do, since the state we left
working LWIP is using the posix layer,
which we observed introduces important overhead, so a further step is
to reimplement the LWIP's HAL
using the RTEMS native API instead. Any plan for that?
I think that would be outside the scope of the student's GSoC effort.
Agreed. This just sets up a repeatable baseline that we won't slip
back from. There have been ports in the past which didn't get to this
public point and were lost to history.
I don't know of any work ongoing to optimize the LWIP port for RTEMS.
We appear to have a wiki page that may be relevant to update with
pertinent details: https://devel.rtems.org/wiki/Packages/LWIP
https://ftp.rtems.org/pub/rtems/people/joel/rtems-lwip/ has what is
now a 10 year old port. It may have been done against the Classic API.
I don't recall but it is there as a reference.
Thanks!
Daniel.
What is your RTEMS configuration so I can try it?
I will try to build it today.
