Hi,
Thanks for the feedback. In the meantime I installed Ubuntu on Vmware and
compiled my
own RT enabled kernel, but - who would have guessed - that does not load
either. I
followed all documents I found that describe the process for TS7300 as closely
as
possible, and the compilation of both modules and kernel worked without any
problems.
What's weird is that I cannot load any kernel using bootload, wether it's RTAI
enabled or
not.
You mention redboot and nfs. Are you on a TS7300 yourself? As far as I know
this is for
72xx only. These systems are quite different in terms of booting.
Nothing happens before the freezes. The system does not even come up when any
other
kernel than the default one is written to part1 of the sdcard. And when I use
bootload, it
just halts and displays the text screen that I saw before hitting enter.
I am really puzzled now. Why does my system not load any other kernel, not even
the ones
that come pre-compiled from the site? And why does it then still work with the
one that it
ships with as soon as I dd it back onto the sd card?
This is the 6th day now, so frustrating.
The system was not particularly cheap, and if a feature like RT support is
advertised on the
website I would expect it to be included, or at least easy to install. I think
the lack of
documentation and support is simply not acceptable...
