Figure 4-7: OTG Application as a Device Snapshot

Another way to use the OTG mass storage is by using the command-line application in the tools directory. To see the list of options supported by this command, use the help option.

#cd /home/1362/objs

#./otgcmd.o help

The following table provides a list of otgcmd.o options and their description:

Table 4-1: OTG Command Line tool Options

Option	Description
host	Becomes the USB bus host on the OTG port. Once it becomes the host, it enumerates any device
	connected to the host on the OTG port
idle	If the OTG device is the bus host on the OTG port, de-enumerates the connected USB device and
	comes out of the bus host.
load	Loads OTG modules
unload	Unloads OTG modules
mount	If the OTG device is the USB bus host on the OTG port and the connected device is a mass storage
	device, mounts both the local OTG device disk and the remote OTG device disk to the mount points.
umount	If the local OTG device disk and the remote OTG device disk are mounted to the mount points,
	unmounts both these devices.
status	Current state of the OTG port and the OTG device disks mount status.
help	Prints help menu.

To operate the OTG mass storage device as a host, connect the other OTG mass storage device through the OTG cable and execute the following on one of the targets:

1.#./otgcmd host

This command will make the OTG mass storage device as a USB host on the executed target.
