This section explains the CDC Abstract Control Model (ACM) Linux gadget driver details, how to configure the Linux source to support serial gadget driver for Zynq® UltraScale+™ MPSoC USB 3.0. Linux: Step by Step procedure for creating Zynq® UltraScale+™ MPSoC USB 3.0 controller’s communication device class functionality

  • Setup to test the CDC functionality with Windows as well as Linux host machineįigure 1: Zynq ultrascale + MPSoC USB 3.0 CDC reference block diagram.
  • How to configure all the Zynq® ultrascale +™ MPSoC Linux kernel and dependent files for the CDC class reference.
  • The CDC design example block diagram and overview.
  • You can typically use it in applications like serial COM or UART communication This design covers: The CDC (ACM) class in the USB Component is used for data communication. This Tech Tip explains how to enable all the configuration options, step by step procedure to use the Zynq® UltraScale+™ MPSoC USB 3.0 controller in device mode and make use of bulk transfer type for a serial communication device abstraction using the USB 3.0. Zynq® UltraScale+™ MPSoC USB3.0 controller supports all four types of transfers. These transfer types are Control Transfer, Bulk Transfer, Isochronous transfer and Interrupt transfer. There are four primary types of communication defined by the USB protocol, based on which any required application can be built without changing the firmware or underlying hardware for different applications. An internal DMA engine is present in the controller and it utilizes the AXI master interface to transfer data.

    The USB 3.0 DRD controller provides an eXtensible host controller interface (xHCI) to the system software through the advanced eXtensible interface (AXI) slave interface. Both can be individually configured to work as host or device at any given time. Summary The Zynq® UltraScale+™ MPSoC USB 3.0 controller consists of two independent dual-role device (DRD) controllers. Designed for ZCU102 Rev1.0 and RevB/C/D Prod silicon Boards Designed for ZCU102 Rev1.0 and RevB/C/D BoardsĢ.

    For example they consist of a certain device class, but also an USB disk that has all the necessary drivers stored so that the device can be installed automatically, without the need to have access to a certain driver software.2. The communications device class is used for computer networking devices akin to a network card, providing an interface for transmitting Ethernet or ATM frames onto some physical media.Īn USB Composite Device is a peripheral device that supports more than one device class. USB communications device class (or USB CDC class) is a composite Universal Serial Bus device class. Refer to: CDC: Communication Device Class for an overview of the CDC class. The CDC ACM class in the USB Host Component is used for attaching communication devices to your system. What is CDC Abstract Control Model ACM? USB Host functions to support Communication Device Class ( CDC) Abstract Control Model ( ACM) USB Devices. USB CDC (Communications Device Class) ACM (Abstract Control Model) is a vendor-independent publicly documented protocol that can be used for emulating serial ports over USB. dev/ttyACM0 or COM1:) and as a USB thumb drive (e.g. This allows the device to be registered on a host computer as a seral port (e.g.
