Hi rtnet and Xenomai users, I have an issue with the latest Xenomai (svn #1962) and rtnet (svn #1095) versions using kernel 2.6.19.1. The very same application worked fine on 2.6.17.7 (same Xenomai/rtnet). My application does the following steps in user space: 1) I open one UDP socket to an embedded device. 2) The timeout of the socket is set to 5 seconds. 3) I send out one UDP message A via rt_dev_send() to the device. 4) Then I wait for the response for A in rt_dev_recv() 5) Directly after the return of rt_dev_recv() I send message B via rt_dev_send() 6) Then I wait for the response for B in rt_dev_recv() Here my PC freezes. I am no longer able to access it, I have to press the reset button on the PC.
I have connected the PC and the embedded device with a hub. This allows me to monitor the network traffic using a second PC. Ethereal shows me, that message B is sent to the embedded device and the response of B is sent back to the PC. Whenever I place a printf() directly after the rt_dev_recv() statements to see what happens, everything works fine and the PC no longer freezes. As mentioned above, when I use the very same application with 2.6.17.7 (same Xenomai, rtnet version) everything is perfect! I have a Pentium 4 Dual core, SMP enabled. Any idea on this strange behaviour? Thanks for any feedback Regards Mathias -- Mathias Koehrer [EMAIL PROTECTED] Viel oder wenig? Schnell oder langsam?
