Thanks a lot for the document and your quick answer Warwick!,

(Sorry Warkwick, i think i sent this mail to you twice, first to your 
private mail)

  I already had installed a cygwin from redhat site and the provided gnu 
tools.
In fact, I am able to compile a configuration and the application 
through these
tools. However i wondered if the gnupro tools provided by altera provided
additional or different features that those of redhat do not provide, 
making
then posible to target applications in a right way. I was tryning to build
configurations and application using gnupro tools. If a get it ill will 
report it.
On the other hand, if i did not missunderstand, the .epk package whose link
you provided should set a memory map and other defaults which should
work right with EPXA1, while the sources one can directly download from
ecos site are ready for EPXA10.

kind regards,
Fernando
