Hi there,

 

I am using a AT91SAM9260-ek board to develop a multiplexing card. I built
Angstrom linux with kernel 2.6.27 and also built in Xenomai 2.4.91 (2.5
rc2). Xenomai features works ok, but I have a problem with the Xenomai uart
driver.. The xeno_16550A serial driver is not compatible with the ARM uarts
and I cant seem to find a compatible one except for writing my own. Also
linux app like setserial, does not work correctly, I also think as it does
not have support for Atmel serial. So the standard solution of killing
serial driver with setserial and then modprobe xeno_16550A does not work..

 

Does anyone have a xenomai serial driver for ARM? Any other help you might
give will be much appreciated..

Thanx

If setserial does not work with the Linux serial driver, it is not
Xenomai's fault, you are asking the wrong list.

Each ARM SoC has its own serial driver. There is a driver for the IMX
SoCs family floating on the mailing list (not yet merged in Xenomai
sources), but not for AT91. I am afraid you will have to write the
serial driver for AT91. If you do that, we will be happy to include it
in Xenomai sources distribution.

Xenomai 2.5 was released, so please upgrade to Xenomai 2.5.1.

I know, just stating that there isn't really support...

 [Gideon Spreeth] 
Thank you, but is there no one around here that's working on it or know of a
driver? would have preferred not to waste time on this if someone already
did it. If not, then I'll probably get going and let you know when I have
something working..

Thanx..
