Hi all,
I'm switching from xenomai 2.5.6 to 2.6.1 using
adeos-ipipe-2.6.38.8-x86-2.11-01.patch
In this test I have 2 threads :
- rx_udp receive udp packets from dsp boards at 1kHz
- boards_test send udp packets at 1kHz
I got segfault in printer_loop thread, the point is that if I change env
var RT_PRINT_PERIOD to about 10 or 1000 (default is 100 ms) I do not
have segfault.
Any suggestion ?
Program received signal SIGSEGV, Segmentation fault.
