TS-7120 MicroSD Card Interface
From embeddedTS Manuals
The TS-7120 has a micro-SD connector. When a micro-SD card is installed, it shows up as /dev/tssdcarda; and if it contains valid partitions, these will appear as /dev/tssdcarda1, /dev/tssdcarda2, /dev/tssdcarda3, and /dev/tssdcarda4 (depending on how the card is partitioned). Any partition with a valid filesystem may be mounted as shown below:
## Make sure the driver is loaded first
modprobe tssdcard
## Mount the first partition
mount /dev/tssdcarda1 /mnt/sd/
