The status seems to be that questions about the status
are not answered here :-)

I checked the FAQ, but whether status questions are 
answered or not isn't in it <hint>

Hi, all--

I've been working on this port over the past couple of weeks...  I've
added a 'pc' platform, which supports 'floppy' and 'ram' startups.  Here's
a quick status report:

- I have a prototype 'floppy' startup which allows an application to be
written on a 3.5" diskette.  This is how I've been running the GDB stub.

- The GDB stub is about 75% in place.  It doesn't know anything about
threads yet, and some of the exceptions aren't supported properly.
However, the breakpoint exception, is working great.

- I've just yesterday been able to get the clock ISR to work, so the 
threading support is next on the list.

- 'make tests' works fine, but only the hal tests (intr, context,
and cache) have been ran.  I'm sure that context still needs some work.

I'm hoping to have the threading stuff figured out by the end of next
week--I'll post it as soon as I feel like it's usable!  Stay tuned...

Is it kernel thread support or GDB thread debugging support you want
to implement? The latter should come pretty much free with the
hal/common stub code.

Hi,
    the x86, pc104 platform still is not on the list of supported
targets. As the toolchain is hosted on x86 I suppose it will be
straightforward to target to this platform.
Is this true?

Thank you,
Roland

hi;

just subscribed, etc

whats the status on x86? x86/pc103/4? amd-sc400?

thankyou!

Currently there is no port of eCos to embedded x86 platforms, but such
a port by Cygnus is now under consideration. This would target
processors from the 386 upwards - support for earlier processors would
be difficult because of compiler issues.

Please see the section on porting in the sourceware FAQ for more
details, http://sourceware.cygnus.com/ecos/faq.html
