    Hi all, when we build the app with DSPLink, the Linux signal cannot work. For example core-dump file cannot be generated again. I mask the signal handle in DSPLink, so DSPLink will not handle the signals, but lots of tasks cannot be killed, as a result, the core-dump file cannot be generated. The...
