Using an SD Card
If you have an SD Card with pictures or other multimedia content, you may use the
3-Stack Board to view its content.
To use the SD Card, follow these steps:
1. Insert the SD Card in the SD Card slot, which is located in the lower part of the
personality board, just below the USB connectors.
The system displays an SD card image in the left side of the display, and mounts the
card in the /mnt/mmcblk0p1 folder. If the mmcblk0p1 folder is not there, then the card
may not have the correct format. If so, then enter the following command:
mx31#fsdisk /dev/mmcblk
• For partition, use the n command.
• For type (extended or primary), use p for primary.
• Accept the default options provided by the prompt.
• To save the changes, apply w.
The SD card will now be mounted in /mnt.
2. Notice the multimedia file locations. By default, the multimedia files are stored in the /
mnt/flc/directory. There are three folders: one for pictures, one for music and one for
video.
• mx31#cp /mnt/<sd_card/picture_file> /mnt/flc/Pictures
• mx31#cp /mnt/<sd_card/audio_file> /mnt/flc/Music
• mx31#cp /mnt/<sd_card/video_file> /mnt/flc/Video
3. Copy the content on the SD card to those folders, storing the picture files to the
Pictures folder, audio files to the Music folder, and video files to the Video folder.
The files are now visible to the multimedia applications.
