Java_net_tinyos_comm_TOSCommJNI_NativeSerial_1didEventOccur
basically the code segfaults in the NativeSerial::didEventOccur()
call.
if I just put a std::cerr << "hello" << std::endl; call into the
function - it doesn't segfault. this suggest that there's some memory
corruption going on here.
and still, it doesn't segfualt, but the mote sill stops sending data
through the serial port (the TX light stops to blink), and won't react
on the data received either. it sort of hangs.
is there a way to use standard javacomm instead of this special
library
to do the serial communication?
Can you get it to dump core and figure our where the bug occurs? That
is, the line of code/memory access?
With a little bit of tweaking, it shouldn't be too difficult to get
the java code working with the standard Java comm. We moved away from
it due to some issues with supporting newer versions of Linux. There
was a time when it was really hard to find.
