2.#./otgcmd mount

This command will mount the local and connected OTG mass storage disks to the specified mount points and the disks are ready for use.

To disconnect the OTG mass storage device, follow these steps:

1.#./otgcmd umount

This command will unmount the already mounted local and connected OTG mass storage disks.

2.#./otgcmd idle

This command will bring the OTG mass storage device to idle state.

To get the status of the OTG mass storage device at any time, use the following command:

•#./otgcmd status

This command will print the current state of the OTG device, the mount status of the local and remote connected OTG device.

In case of VBUS error, you can clear the status using:

•#./otgcmd error

This will clear the error condition on the USB bus
