 3. Build the runtime with the pre-processor flag that enables tracking of debug events. Instructions are in the [ETDump documentation](./sdk-etdump.md).
 4. Run your model and dump out the ETDump buffer as described [here](./sdk-etdump.md). (Do so similarly for the debug buffer if configured above)
