Hi,
I have an RTAI app working on a TS-7260 but it is unstable. The problem is
difficult to trace since it occurs after hours of heavy use and normally
results in a hang of the TS board (sometimes I get an oops).
My system has tight timing requirements of multiple serial ports. I modified
the RTAI serial driver to work on ARM (the one in RTAI 3.2 only works on i386)
so it might be the serial driver that is at fault. I have tried moving my user
mode RTAI code to kernel and still have the lockups. I have also tried the same
code without RTAI and it works fine.
Anyone have any ideas how to go about debugging RTAI code? My only option seems
to be to get hold of a JTAG debugger and connect to the appropriate pins on the
EP-9302.
I'm going to try the 2.6 (non RTAI) kernel next - I might be able to get away
with using the 2.6 scheduler. On 2.4 (ts11) I get a minimum 10 ms delay (1
tic?) every time I try a non-blocking select() or read().
