Using a USB Mass Storage Application
If the SD card is plugged and detected by the system, then you can run the USB Mass
Storage application, which allows the system to be seen by a PC as an external hard disk
driver that contains the content stored on the SD card.
This allows you to transfer information from the PC to the system and from the system to
the PC.
The information transferred from the PC to the system is stored on the SD card. You can
send multimedia files from the PC to the system, store them in the SD card, and then copy
them to the /mnt/flc directories
To use a USB mass storage application, follow these steps:
1. Make sure the SD card is plugged in and detected.
2. Connect a B-type to mini-AB cable from the USB mini-AB port (which is the OTG
port in the Personality board), to a USB port in the PC.
3. Select the Mass Storage mode.
4. Click on the Launch button.
The application is launched, and the PC will detect an external mass storage device.
Typically, the drive is seen as Drive F. Now the system can load information to this
drive as if it were a regular mass storage device.
After the files are stored in the SD card, repeat the steps in the previous section, Using
an SD Card, to make the files visible to the Multimedia applications.
Running the Applications
Now that the system contains the multimedia files, you can run the applications. First, see
“Supported Codecs”
for a description of the software packages supported by the system.
Running the Video Application
The Video application enables you to view video files.
To use the Video application, follow these steps:
1. In the Multimedia Menu, select the VideoPlayer application.
2. Click on the arrow that is located in the top of the display in the right corner (near the
cross button).
A menu displays video options such as Open File, Playlist, and About.
3. Select Open File.
The /mnt/flc/Video folder is displayed, listing the files previously saved.
