===Accessing the peripheral in ORCA SOM===
Once initialized, the SD device is mapped to the standard <code>/dev/mmcblk0pXmmcblk1pX</code> block device, depending on how many partition are created on the SD card.
====Linux messages at boot time====
[ 3.245015] EXT4-fs (mmcblk1p2): mounted filesystem with ordered data mode. Opts: (null)
[ 4.792069] EXT4-fs (mmcblk1p2): re-mounted. Opts: (null)
