+            that you want to play (.WAV is only format supported as of this
+            writing).  That SD card should be inserted in the HSMCI0 media
+            slot A (best done before powering up).
+
+         b. Then from NSH prompt, you need to mount the media volume like:
+
+           nsh> mount -t vfat /dev/mmcsd0 /mnt/sdcard
+
+         c. Then you can run the media player like:
+
+           nsh> nxplayer
+           nxplayer> device pcm0
+           nxplayer> play <filename>
