Hi,
lwIP can be built using RTEMS Source builder now. We have RTEMS +
lwIP OS glue(cc.h & sys_arch.c etc) . But it uses posix lib functions
instead of RTEMS native library.
https://github.com/ragunath3252/lwip-nodrv . It's tested and working
but not fully optimized.

Hi Marcos,
Great news! I did not find any solution to the issue. I have a REV C board
from element14. Is this the same board you are using? In my board I saw
the issue.
Does this have anything to do with the patch you submitted [PATCH]

Hi Thomas,
There is no need to manually edit the makefile. You can add whatever
files you need from freebsd to libbsd.py file.
I can see, there is already a dev_usb_input module. It is currently
disabled. You can just enable it & add additional files to it if you
need.
Then you run the freebsd-to
Hi All,
I have written a blog explaining how to use lwIP with RTEMS. The BSP
supported is BeagleBone Black(BBB). It basically has four steps
1. Build BBB BSP with cache disabled.
2. Build lwIP library. We can build it using RSB
3. Build driver library using RSB
4. Build the application

Hi Yurii,
For RPi USB support, can you pls try including
"default-network-init.h" in the application (I tested with netshell01)
instead of "default-init.h" and see if it works.
If we use default-init.h, nexus.content is empty and device is not probed.
Thanks,

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

only lwIP sources. I will be sending another patch for the driver to

Hi Sebastian,
If we want to use cache flush/invalidate calls, what is the general
method one has to follow?
I saw the if_cgem driver, but it is somewhat different from cpsw
driver. What are all the places which may need these calls?
Thanks,

Hi Sebastian,
I read about rtems_cache_coherent_allocate(). I understand first we
need to add an area to use this.
I added rtems_cache_coherent_add_area(bsp_nocache_heap_begin,(uintptr_t)
bsp_nocache_heap_size); in bsp start.
Is that right? I do not know how bsp_nocache_heap_begin &

our earlier correspondence (regarding lwIP). You mentioned that t

What can be the correct fix for the issue as there are other
interrupts that are not processed in this way?

What is the procedure to link a network driver to the application in
rtems libbsd port? The drivers are compiled and available in the
libbsd archive. I dont know how to link the driver to the application.

the following str

I would like to know what is the status of running lwIP on beaglebone

Hi All,
I was exploring the beagle code base to find a task to get hands on
experience with RTEMS internals. I found that "Real time Clock (RTC)" support is
missing for beaglebone. I made the effort to add the driver for the device.
Included the patch for the driver. RTEMS already have a RTC frame
