PLAYING MULTIMEDIA
USING THE SD/MMC SLOT
COMPILING USER APPLICATIONS FOR EMBEDDED LINUX
The default installation includes a command-line multimedia player. To
play audio or video start the media player giving the media files as
command line arguments:
The sound volume can be controlled either from the GUI or by the
command-line ALSA application:
Volume channels are selected by the left and right arrow keys, values can
be changed with the up and down arrow keys, mute is controlled by the M
key, and the ESC key exits the application. Note that certain terminal
emulation programs cannot cope with the alsamixer output. HyperTerminal
is known not to work. PuTTY is known to work.
WARNING:
sometimes the OSS-emulation layer in ALSA does not work properly,
particularly in situations when the original sound stream must be down-
sampled. In these cases the sound will be distorted. MPlayer can be forced
to use ALSA with the -ao alsa command line argument:
WARNING:
color depth for the frame buffer. Fix that by forcing the video output driver
to SDL:
A few limitations arise when using the SD/MMC slot:
CAVEAT:
prevent it from working properly with some SD/MMC cards. Please consult
the chip errata for more information.
1. AT73C213 sound cannot work in Linux.
2. ADS7843 touchscreen cannot work in Linux.
3. Generic SPI cannot work in Linux.
4. Before and during booting the jumper AT/SD must be in position
5. The SMD jumpers WP_E and CP_E must be soldiered.

“AT”. After Linux kernel is loaded and running, this jumper must be
placed at the “SD” position.
A specially configured version of the Linux kernel must be used. A
precompiled binary can be found in the “sam9-l9261-samba-
sdmmc.zip” archive. The configuration for this kernel can be loaded
in the kernel source tree with the following command
The AT91SAM9261 MCI controller has a few bugs which can
If colors seem to be messed up then MPlayer is not using 24bpp
By default MPlayer uses the OSS sound interface. But
