Does RTLinux run on the MPC8260? I thought it should, but can't get
it to work.
I've tried a couple different kernel versions, but no luck. I tried 2.4.0
from kernel.org, but it wouldn't compile at all. I can run a 2.4.1 without
the RTLinux modules. If I apply the patch, to 2.4.1, I get several failures,
and it looks like the powerpc changes are already in the kernel. I can still
build the kernel, however.
With 2.4.1, when I try to build the modules I get this error:
rtlinux-3.0/include/rtlinux_signal.h:67: `NR_IRQS' undeclared here (not in a
function)
If I define NR_IRQS to be 256, it compiles OK.
So I can boot the kernel, and when I do a 'insmod rtl.o', I get:
RTLinux Extensions Loaded (http://www.fsmlabs.com/)
Kernel panic: request IRQ
I've also tried a bitkeeper kernel with no better luck.
I saw in an old mailing list posting that XMON or KGDB needs to be
enabled on the powerpc to get RTLinux to work, but the kernel won't
build with either enabled.
So am I doing something wrong, or does RTLinux not work on the 8260?
Thanks.
