Hello,
I am trying to get RTAI to work on a TS 7300. First I downloaded rtai-3.2-magma-
compiled.tar.gz from ftp.embeddedarm.com but could not execute the testsuite
applications since things were compiled for a different Kernel. E.g. running
/usr/realtime/testsuite/kern/latency/run leads to:
/usr/realtime/modules/rtai_hal.o was compiled for kernel version
2.4.26-ts9-rt
while this kernel is version 2.4.26-ts11.
I am confused now about the nature of the ts11 kernel. Does it come with RTAI
support
built in or not? Is it a question of simply recompiling RTAI, or do I need a
new kernel too?
On http://www.embeddedarm.com/products/board-detail.php?product=TS-7300 under
Software it clearly is stated:
"The Linux solution for ARM is compatible with the RTAI real-time extension"
>From this I would expect things to just work. But now I already spend the 4th
>day trying to
get this to work with now luck. The fact that there is very little
documentation about it
does not help a bit.
Here is what I've tried so far:
I downloaded an alternative kernel and kernel modules from the ftp server that
state to
have RT support built in (vmlinux-7300-ts11-rt.bin) and used bootload to try to
get it to
load, but the system froze each time. I then wrote the kernel to the first
partition of the
sdcard, but that did not boot either. I tried to compile my own Kernel under
Cygwin but
failed since I did not manage to install modutils. Now I tried to use bootload
to load the
kernel that the system already comes with, extracted from the first partition
of the default
sdcard image just to see if bootload works at all, and even this results in
freezing.
I am obviously not getting anywhere with this. There must be others here who
face similar
problems. How can I get RTAI to work on this platform? Do I need a new kernel
at all? How
am I supposed to use bootload on TS 7300 to get any results?
I am very thankful for any help.
