Hum? In which way did you make the change? Did you choose __FOO or _FOO?
And in which file did you make a change? Is this in the config tool or some
macros in the hal?

Thanks

It's to do with the use of CYG_LABEL_DESC() macros in the MLT .h files.
But  it has also occured to me that the configuration tool binary that is
up for FTP at http://sources.redhat.com/ecos/anoncvs.html does not support
the generation of the MLT .h files correctly yet. The Configuration Tool
sources in anonymous CVS do though, although they require MS VC++ to
build(!)

John D: when you get back, can you show Julian how to do a build of the
Configuration Tool that we can make available publically?

NB: Most of the team here is going to be out of e-mail contact for the next
week, so expect an absence of responses from us on ecos-discuss.

This has been fixed in anonymous CVS.

I just try the solution you gave me some time ago, but it seems that in the
target.ld script the symbol is __FOO while the .h file  assume it is _FOO.
Don't know which is worng and where this should be changed.

Do you really need it? If you include the appropriate MLT generated .h file
(by using
#include <pkgconf/system.h>
#include CYGHWR_MEMORY_LAYOUT_H
) you can get the end by using (&CYGMEM_SECTION_FOO +
CYGMEM_SECTION_FOO_SIZE).

Other than that, you would need to rebuild the config tool. The sources are
in the CVS repository, but require MSVC++ to build them.

[ECOS] Memory map: User defined section

[Fabrice Gautier]

Hi,

When I define a new section in the memory map with the config tool, I would
like to have a symbol at the end of this section. Currently, if I define a
section FOO, there is a symbol __FOO defined at the beginning, and I would
like to have a __FOO_END at the end.

How is it possible to had this feature? Does it require a change to the
config tool itself?

Thank you
