There's no reason to run .read() and .read_gpio() in the same thread. .read() reads everything, including the GPIOs. The only reason you'd ever use .read_gpio() is if you wanted to read GPIOs faster than the servo thread, you could put .read_gpio() in a faster thread. I think there should be nothing in your base thread with hostmot2. The base thread is in the FPGA. If you meant that the servo thread is running at 100,000 ns, try slowing it down to 1,000,000 ns and see if that helps the lockups. Wouldnt help the reboots though, that's strange... If you can, get the machine to just before you add the .write(), and send us the output of dmesg and "halcmd show all". -- Sebastian Kuzminsky how many no money boys are crazy how many boys are raw how many no money boys are rowdy how many start a war ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
