+Then you will need to build the recovery binary and squeezelite binary:
+```
+# Build recovery.bin, bootloader.bin, ota_data_initial.bin, partitions.bin  
+PROJECT_NAME="recovery" make -j4 all EXTRA_CPPFLAGS='-DRECOVERY_APPLICATION=1'
+# Now force a rebuild by touching all the files which may have a RECOVERY_APPLICATION specific source compile logic

 Once the application is running, under monitor, you can monitor the system activity.
