Figure 4-9 OTG B closing the session after connected device data access

Figure 4-8shows the screen capture of otgcmd.o utility when running on the Accelent IDP platform. It shows the execution of otgcmd.o for current status, becoming usb host, mounting the connected device disks and accessing the connected OTG mass storage device (A device) files.

Figure 4-9shows the screen captures of otgcmd.o while copying files from connected OTG mass storage disk to the local disk, playing an MP3 file from the connected OTG mass storage device, and going back to IDLE state. It also shows the screen capture of help option with otgcmd.o

Figure 4-10shows screen captures of OTG B device status as peripheral when connected to OTG A host, accessing the local disk files when in IDLE state and OTG status as OTG A device.
