Ugh, things are not going well. So far, this is a stock
build from source (plus the default binary load from the
.iso download.)
So, when I run the binary version 2.7.14 with a NetMos PCIe
parport card, it does not communicate properly, as
expected. If I put in the epp_dir=1 option on the loadrt
command line, I get "unknown symbol in module". (I thought
2.7.14 would have had that option available in the hal_ppmc
driver.
I thought it went in at 2.7.9 or so.)
But, if I run the compiled from source version (2.8.0~pre1)
I get a kernel crash of varying flavor.
Sometimes I get a panic screen with kernel null pointer in
PREEMPT SMP, other times it locks up a couple seconds after
loading the hal_ppmc driver. Hmmm, that could be pretty
tough to debug.
(2.8.0~pre1 runs fine with software stepping to the parallel
port. It also seems to run fine with a Siig parport card
using the sample config that came with 2.8. If I use one of
my old configs, I also get the
kernel crash. I will have to compare the config file set to
see what could be different.)
This system was loaded from an old .iso DVD, but I didn't
think there was any update to the OS.
It is 3.4-9-rtai-686-pae #1 SMP PREEMPT Debian 3.4.55
LinuxCNC i686
The above is a bit confusing - rtai OR preempt? I didn't
think it could be both. But, I think I did the make with
the preempt option, so if the kernel is rtai, maybe that is
the problem.
Well, any comments would be very welcome!
