Dear Alfredo,
I think that the problem is not the mount. I had this problem but I resolve
it in a strange way.
First of all are you sure that you have the the Cygwin B20 release?
Remember to patch the gcc before configure it.

I hope that this can help you.

Nothing :-/. I've been trying to find the best workaround for what is
actually a cygwin bug.

Okay. Let's try a different approach. Please download the May 25th snapshot
of the cygwin1 DLL from http://sourceware.cygnus.com/cygwin/snapshots/

i.e. cygwin1-20000525.dll.gz

Uncompress it with "gunzip cygwin1-20000525.dll.gz" and then exit all your
running cygwin applications. Now go to the "bin" subdirectory of your
cygwin installation and rename "cygwin1.dll" to "cygwin1.dll.old". Now copy
in the uncompressed cygwin1-20000525.dll and rename that to cygwin1.dll

This should fix the problem and you can continue.

Note that snapshots after the 25th May and up to (at least) the 31st May
definitely do not work - they are very broken in other ways - so do not
install those.

I have been patiently waiting for the cygwin team to produce an official
1.1.2 update to the cygwin DLL which includes this bug fix, but
unfortunately it still hasn't happened.

Let me know how it works out.

eCos uses features only found in GNU cc, so unfortunately that isn't an
option worth pursuing.

I believe the right way to go about running eCos with the ARMulator is to
do a port of eCos to it. The reason is because eCos does not interwork with
Angel on the boards, using the ROM monitor interface for I/O etc. To port
eCos, the platform HAL would have to provide low-level communication with
RDI/RDP.

I don't know in detail how much work would be involved with that. We don't
currently have plans to do it ourselves, so a contributed port would be
welcome.

The ecos build now is OK and I tried to compile some file automatic
generated by VCC and all is OK.

But I'm brave and I'm thinking to use an ARM instuction set simulator. This
simulator need the RTOS library but the ones generated by the configuration
tool (libtarget.a) doesn't work.
There is the possibilities to compile the library for another compiler (in
this case armcc by arm) ?

THANKS

[snip rest]

Can you try deleting the file hal/arm/arch/v1_3_1/arm.inc in your build
tree and trying the make again (which will recreate arm.inc). If it still
doesn't work, please send us the arm.inc file.
