6. Connecting the board to computer
Linux installed by default on onboard flash.
The serial port is set to baud, 8N1, with no flow control
In Linux- the minicom program is configured using the “-s” parameter (minicom -s)
In Windows, Putty or HyperTerminal can be used

8. Connecting an USB thumb drive
2 USB 2.0 ports available
USB flash drive has to be formatted as either ext2 or vfat
TS-Linux comes with USB drivers
After booting at command prompt do
“loadUSBModules.sh”
“mount /dev/scsi/host0/bus0/target0/lun0/part1 /mnt/”

12. Connecting a SD card
A binary Linux driver module and a set of generic, OS-independent read/write routines is in ARM object (.o) file by default
After the SD Card module is loaded, the device entry “/dev/sdcard0” is used to mount into the file system.
“mount -t ext2 /dev/sdcard0/disc0/part3 /mnt”
