   > @YuuichiNakamura, @xiaoxiang781216 this is looking really nice. Is there any documentation with the setup instructions that I can begin testing with?
   
   @davids5 Sorry. https://github.com/YuuichiNakamura/nuttx-task-tracer-doc is the document but it is already outdated and I have to update it. As I answered to @v01d , I'll maintain the documents for the new document system after the branch is merged.
   
   To try it instantly, use https://github.com/YuuichiNakamura/incubator-nuttx-apps.git feature/task-tracer branch as the app code,
   and enable the following configs.
   ```
   CONFIG_DRIVER_NOTE=y
   CONFIG_DRIVER_NOTECTL=y
   CONFIG_SCHED_INSTRUMENTATION=y
   CONFIG_SCHED_INSTRUMENTATION_FILTER=y
   CONFIG_SCHED_INSTRUMENTATION_IRQHANDLER=y
   CONFIG_SCHED_INSTRUMENTATION_SYSCALL=y
   ```
   Then `trace` command is added to nsh. After that,
   ```
   trace mode +s
   trace cmd "sleep 1"
   trace dump
   ```
   This can get the trace while executing "sleep 1". The log output can be used as the input for tracecompass.
