I am going to start trying to see if I can figure out what is not getting
set.
By the way. This board also has 4 other serial ports on a 8250.c driver. It
also fails under the xeno build.

Don't bother for these build bugs, they were innocuous and due to 2.6.0
being the first code drop of a major release.

I actually think that CONFI
I actually think in is in the settings because if run just the setup part of
the code without reading and writing, on the kernel that works my activity LED
turns off.
On the xeno kernel the LED never changes.

Note that this driver has the same issue as the vanilla atmel serial:
Hello,
the issue I am describing here happens on a dual-core Atom (without
hyperthreading)
It is easy to reproduce with 2.6.32.7+xenomai 2.5.2, which was my
initial configuration until

You do not know that, as you do not check write return value.
Any chance to see the driver code? Without that, I am afraid we can not
help.

Gilles.
I don't get any error from anything.
I just don't get anything back from the read command.
This is how the program behaved without the tcsetaddr command previously.

Why closing and reopening? Are you sure this does no
My arm embedded system is set for 2.6.29 so I think I have to use that

That is completely outdated, please use one of the I-pipe patches which
comes with xenomai 2.6.0 (since you are using xenomai 2.6.0).
