console is ttyO2, not ttyS2.

I have asked you this several time, but please stop using the Xenomai
mailing list instead of doing your homework. Everything about pandaboard
is documented on its wiki. Use the wiki first, then ask questions on
this list when you do not find them here.

Really, installing Xenomai takes five minutes when you know how to do
it, at most one day when you are a beginner.

You have been asking questions on this mailing list for weeks. And at
every step, we do your work in your stead, and you learn nothing.

Don't you see that there may be a problem?

Dear Giles ,
that is not problem because of ttys2 or O2 settings . I followed
http://omappedia.org/wiki/Minimal-FS_Booting

that and  the below bootargs

fatload mmc 0:1 0x80000000 uImage
setenv bootargs ro elevator=noop vram=32M
mem=460M@0x80000000mem=256M@0xA0000000root=/dev/mmcblk0p2
console=ttyO2,115200n8 fixrtc earlyprintk  bootm
0x80000000


still i did not saw anything on my terminal . then only i sent a mail to
xenomai help mailing list .

Then there is probably something wrong in your configuration. Please try
the configuration I pointed you to.
