Hi
When the xenomai 2.6.3 patch on my device, there are some problems. H/W spec - Am3352 ARM Cortex-A8 - Beaglebone Black base board. S/W spec - Kernel Version: v3.8.13-bone79 - Xenomai 2.6.3 patch - Ubuntu 14.04.4 LTS The first problem. When in use the application program “clock_gettime” function quickly (about 5ms), the spinlock occurred in the kernel. See kernel message file (“dmesg” command), file name = dmesg_spinlock.txt A Second problem. Using a "rt_mutex_create" function in the parent program when generating a "MyMutex", performs "rt_mutex_acquire", "rt_mutex_release" quickly, and the problem occurs once in 5-7 days. Kernel messages of the problem. (“dmesg” command) “Xenomai: native: cleaning up mutex “MyMutex” (ret=0).” I want to know what the cause or the solution to the two problems. And just ask. -------------- next part -------------- A non-text attachment was scrubbed...
