[ECOS] porting ecos

[ECOS] porting ecos

[smith jj]

Hi
we are porting ecos to our board based on arm core. i have taken the
base of an existing bsp based on arm9 and trying to make changes
there.
we already have the binary image of redboot for the board so i started
with CYG_HAL_STARTUP==RAM and built an OS image(application+library).
however when i try to execute the image on baord using led code i
could find that it crashed in function cyg_hal_invoke_constructors in
vectors.s itself. i tried to find out the functions which could be
invoked by this but cant find any link..
using earlier archive mails i found under gdb using x &__CTOR_LIST__ i
get the adrress which is the function pointer but i cant proceed from
there as to how to make cyg_hal_invoke_constructors pass.
can anyone please help me with how to proceed further...how can i make
this constructors invoked correctly..

regards
smith

Have you read the documentation?  In particular the "Getting Started" guide?

What board?  If it runs RedBoot, [at some level] it already runs eCos.

Firstly, for the Cirrus Logic board you mention, no porting is required
at all as this is one of the platforms we support.

Secondly, you would be much better off by using the eCos sources from
anonymous CVS.  See http://sources.redhat.com/ecos/anoncvs.html

Once you've obstained the latest sources and installed both the sources
and the tools on your system (I assume that you are using Linux for
your development host, based on your references above) then you can
create an eCos kernel for your board.  Once you have a kernel, then
you build and run applications on the board by downloading them using
GDB.

This whole process is rather fully explained in the eCos "Getting
Started Guide" and hardware installation notes.  The full text is
available from our web site at:
  http://sources.redhat.com/ecos/docs.html

If you have additional problems or questions, just send them to
this same eCos discussion list.

[ECOS] porting ecos...

[김재용]

Please help me..
I don't even know concept of porting, but I have to port ecos in EDB7209-2C
ARM7 board of Cirrus..
I have followed instruction in redhat Web Site and downloaded ecos-1.3.1
and
extracted...
And compiled, installed binutils, gcc, gdb in arm target, following
instruction
of
http://sources.redhat.com/ecos/install-linux.html and
http://sources.redhat.com/ecos/tools/linux-arm-elf.html
executable comes arm-elf-gcc etc.

and I don't know what I should do next to port ecos.
I guess I have to cross-compile kernel, but I don't know how to do that.
Neither document in redhat Web site nor document in ecos package told me
what
to do next. and seems to skip..
Please tell me what I should do next in detail, including command with
option
and argument. Sorry, I am beginner in ecos and porting
I have not much time and urgent.
And another question..is ecos included in Embedded Linux?
Please answer..
I will wait for your answer.
