[ECOS] New GDB stubs and EDB7212, more questions

[root <larwe at larwe dot com>]

Sorry guys, I've got some more dumb questions.

First, reading through the ECC's I see that there are a lot of places
where something is assigned one value if the CPU variant is EP7211 and
another if it's EP7209. In few or no places is the 7212 mentioned. Does
that mean that if I configure for the 7212, I'm going to get "empty" or
"non-defaults" in those values? Should I leave it at the default 7211
configuration? The impression I get is that things have been actively
maintained for the 7211 and 7209, and the 7212 is not so actively
tested.

Second, I've built new stubs from the current CVS sources and
successfully flashed them. However now I'm worse off than I was using
the 1.3.1 stubs; I load my new binary (rebuilt, and linked against
latest anoncvs). When I continue, the board just sits there. I
breakpointed cyg_user_start and main and either breakpoints aren't
working, or it never got that far, because gdb just sits there at the
"Continuing." message. Is there some special pre-initialization I was
supposed to add to my program?

Should the below generate a valid set of stubs for EDB7209 (with
EP7212)?

mkdir ecos_temp
cd ecos_temp
ecosconfig new edb7xxx stubs  [a few "attention" messages about changing
defaults]
ecosconfig tree
make
dl_edb7xxx install/bin/gdb_module.bin 115200 /dev/ttyS0

When I load the binary and try to single-step, I get "cannot find bounds
of current function", so it's hard for me to see if anything is actually
happening.
