Hi there,
I'm currently working on setting up rtnet on a gumstix running xenomai
2.4-rc3 / linux-2.6.20. Everything works fine up to the point where I
try to ping rtlo as in, try running "rtping 127.0.0.1". As soon as I
run that command, the system freezes. I am accessing the gumstix
hardware using a serial console which also displays kernel messages
but there is nothing suspicious to be found.
When playing around with xenomai, I noticed the same "kind" of freeze
trying to run the latency test with the default period of 100us so at
first I thought it might be a problem with the relatively slow cpu
used on my gumstix (it's an intel xscale pxa255 with 400mhz) but I'm
not too sure about this. I'd really appreciate any pointers you can
give me as I am quickly running out of good ideas myself.
Other useful information about my setup and what I did:
steps to make rtping freeze:
# cd /usr/local/rtnet/
# insmod ./modules/rtnet.ko
*** RTnet 0.9.10 - built on Nov 2 2007 13:09:41 ***
RTnet: initialising real-time networking
# insmod ./modules/rtipv4.ko
# insmod ./modules/rt_loopback.ko
initializing loopback...
RTnet: registered rtlo
# ./sbin/rtifconfig rtlo up 127.0.0.1
# ./sbin/rtifconfig
rtlo Medium: Local Loopback

# ./sbin/rtping 127.0.0.1
Real-time PING 127.0.0.1 56(84) bytes of data.
