Mounting an USB drive on the DM365 Leopard Board
From RidgeRun Developer Connection
LeopardBoard 365 USB Host Examples
Leopardboard v1.3 and newer supports USB device mode and host mode. By default, the hardware is set to device mode.
For host mode, you need to make sure J1 and J4 are set properly. These jumpers are located on the opposite side of the board as the USB connector. For host mode, install a jumper and J1 and jumper pins 2 and 3 on J4. J4 pin 3 is the pin closest to R31.
To use common USB devices, a USB A Female to Mini B Male converter is needed.
USB Mass Storage Device Example
In order to do this an USB A Female to Mini B Male converter is needed. Connect the converter to the board and then the USB drive to the A female side. The USB drive mounting point will be /dev/sda1 so in order to explore the drive contents the following commands must be executed on the target:
cat /proc/partitions mkdir /tmp/drive mount /dev/sda1 /tmp/drive mount cd /tmp/drive ls
Plug in the USB mass storage device:
