Hi Oleg

Thank you for your feedback.

I would appreciate if you do so.

I assume it that by vanilla "lwip 1.4.1" you mean the lwIP 1.4.1 release, and
the other is current lwIP source (from GIT). Am I right?

Assuming that my assumption above is right...

I would:

  1. download vanilla lwIP 1.4.1 master. (i.e. without eCos). ->
lwip-1.4.1-master
  2. download or check out current lwIP source (i.e. the source that I want to
upgrade to. -> lwip-current
  3. Diff 2. vs 1. Something like: diff -ruN lwip-1.4.1-master lwip-current
>lwip_upgrqade.diff

  4. Study lwip_upgrade.diff and try to apply changes to eCos' lwIP 1.4.1. With
little luck it may be possible to just patch it over eCos lwIP.

I hope this helps and I'd appreciate some feedback.

Ilija

            Bug ID: 1001989
           Summary: Cortex-M linker script template does not accept user
                    selectable grouped libraries.
           Product: eCos
           Version: CVS
            Target: All
  Architecture/Host Cortex-M
                OS:
            Status: NEW
          Severity: enhancement
          Priority: low
         Component: HAL
          Assignee: unassigned@bugs.ecos.sourceware.org
          Reporter: ilijak@siva.com.mk

Created attachment 2514
  --> http://bugs.ecos.sourceware.org/attachment.cgi?id%14&actioníit
Fix Cortex-M linker script to accept user selectable grouped libraries.

eCos HAL macro CYGBLD_HAL_LINKER_GROUPED_LIBS provides for user selectable
grouped libraries.
In Cortex-M linker template cortexm.ld grouped libraries are hard coded. The
submitted attachment introduces the macro to linker script.
