[ECOS] ROM lib on Triscend A7 compilation

[Fabrizio Sebastiani <fsnergalists at inwind dot it>]

I had some problems with the "eCos 1.3.1 for Windows" configuration tool 
when compiling the cygmon library.

I previously added the Triscend a7eb.epk package to ecos.db using the 
administration tool.
This package is provided by Triscend and I followed step by step the pdf 
guide "Triscend_a7hal_users_guide.pdf"/"building the cygmon ROM".

After  upgrading the two tools Configtool.exe and ecosconfig.exe
(as described in "Updated configuration tools for Windows"  from 
http://sources.redhat.com/ecos/anoncvs.html),
I tried to build the ROM lib but I got the following unresolved reference:

I changed the definition of "__vectorend" to "__vectors_end" in file 
C:\Program 
Files\RedHat\eCos\packages\hal\arm\a7eb\v1_0_0\include\hal_platform_setup.h 
and now compilation works.

Is it really correct? Has anybody already encountered the same?

Maybe some other clean solution?


  thanks for attention :-)
