Hi
https://software.intel.com/en-us/vtune-cookbook-profiling-linux-and-qnx-system-boot-time#QNX
with Inter VTUNE user guide above on QNX, I want to get more datas necessary for analyzing processes running in target board with VTUNE Profiler. However, I found that segmentation fault error happens in target board when typing "./sep -p2" to send call-stack datas to host PC.
(refer to attached picture)
Environment of target board is with Intel Denverton and operating system QNX.
Environment of Host PC is with windows 7 and VTUNE Amplifier 2019 Update7
But, If executing sep without any options in target board , It works well. (ex typing only "./sep" and enter). and VTUNE Profiler can get datas from target board. (but there are not call-stack datas because not adding "-p2"
Why is the segfault error made when with QNX environment?
Best Regards

Unfortunately this is a known problem with QNX 7 and the -p option, and it is not planned to be supported in the near future.
Hi Lee,
We are forwarding this case for SME to check. Meanwhile could you please post the output of the below command to help us debug the issue
