I'm trying to use Hokuyo laser scanner(URG-04LX) on gumstix.
Although successfully built hokuyo_node package, alignment exception fault
but getID and getFirmwareVersion worked find.
Device at /dev/ttyACM0 has ID H0907156
Device at /dev/ttyACM0 has FW rev 3.3.00(16/Apr./2008)
hokuyo_node produced this kernel error message.
Alignment trap: not handling instruction ed868b00 at [<0002f6be>]
Unhandled fault: alignment exception (0x801) at 0x000875bb
/opt/ros/cturtle/ros/bin/rosrun: line 35: 729 Illegal instruction
Does anyone who experience this kind of error or know how to handle it?
Please let me know.
Many thanks in advance.
