Does this simulator support the *exact* peripheral set that eCos is looking
for? Where/how did you get/build it?
Gary Thomas <firstname.lastname@example.org>
What do you mean by peripheral? I installed eCos as described in the
documentation (http://ecos.sourceware.org/getstart.html) on a Mandrake 9.2
distribution. I know this is working, as I have build eCos and linked it
with the hello world program, and executed it succesfully on the board. As
far as I have understood, the board is directly supported by eCos. Do I need
to configure anything particular about the simulator? Is it correct that I
need to build the tree for "ROM startup", when I want to run my program on
the simulator without any monitor? An earlier post on this mailing list
(http://sources.redhat.com/ml/ecos-discuss/2003-05/msg00138.html) shows an
example of succesfully simulation upon this board. He doesn't mention any
particular config for the simulator.
I appreciate your response.
