Ethernet Router/Gateway A Router or Gateway is used to translate one protocol to another. It is also used when the physical layer changes mediums. Ethernet to fiber At one time there was a difference between a router and a gateway. The gateway was strictly used as a medium translator ( electrical ) and the router was strictly used as protocol translator ( software ). Now routers and gateways are normally combined and called a routers. Note: Ethernet to WiFi is a router functionality.
*Media Independent Interface (MII) • The MII links the Ethernet MAC with the PHY. Media Access Controller (MAC) • The MII electronics may be linked to an outboard transceiver through a 40-pin MII connector and a short (0.5m) MII cable. TXDn_<3:0> TX_ERn TX_ENn TX_CLKn RXDn_<3:0> RXDVn RX_ERn RX_CLK n CRSn COLn PHY with MII Magnetics/Fiber Transceiver • An MII may support both 10-Mb/s and 100-Mb/s operation, allowing network devices to connect to both 10BASE-T and 100BASE-T media segments.
*Autonegotiation Auto-Negotiation is the exchange of information about each stations abilities over a link segment allows the stations to achieve the best possible mode of operation. The highest performance mode of operation that Auto-Negotiation can achieve is based on a priority table. The Auto-Negotiation protocol contains a set of priorities which result in the devices selecting their highest common set of abilities.

Ethernet Definition… Ethernet - http://dictionary.reference.com/search?q=Ethernet A local area network first described by Metcalfe & Boggs of Xerox PARC in 1976. Specified by DEC, Intel and XEROX (DIX) as IEEE 802.3 and now recognised as the industry standard. Data is broken into packets and each one is transmitted using the CSMA/CD algorithm until it arrives at the destination without colliding with any other packet.

IP IP - Internet Protocol The IP defines how a network of more then 2 devices is formed. IP is the network Layer. IPv4 uses 32 bit addressing IPv6 uses 128 bit addressing A IPv4 node is defined by its IP address, and subnet mask. • IPv4 sample address 192.168.1.0 subnet 255.255.255.0 A IPv6 node is defined by its IP address • 2001:0DB8:0000:0000:0000:0000:1428:57ab Freescale Semiconductor Confidential and Proprietary Information.
IP Classes With IP V4, there are not enough IP addresses for everbody. To solve this problem, subnetting is used. IP addresses consists of 2 parts, a node address and a network address. The class of the address and the subnet mask determine which part belongs to the network address and which part belongs to the node address. Each class is defined by the first 4 bits of the IP address.
IP Subnetting Each IP address contains a node address and a network address. The subnet mask determines which bits identify a node address, and which bits identify a network address. The network bits are the 1’s, the node bits are the 0’s. Default subnet masks • • • Class A – 255.0.0.0 Class B – 255.255.0.0 Class C – 255.255.255.
IPv4 network classes Your IP address identifies the “neighborhood” your node is in. “Private IP addresses” are not assigned by the IANA (Internet Assigned Numbers Authority) Addresses 0.0.0.0 - 0.255.255.255 CIDR Equivalent Purpose RFC Class Total # of addresses 0.0.0.0/8 Zero Addresses RFC 1700 A 16,777,216 10.0.0.0/8 Private IP addresses RFC 1918 A 16,777,216 127.0.0.0 127.255.255.255 127.0.0.0/8 Localhost Loopback Address RFC 1700 A 16,777,216 169.254.0.0 169.254.255.255 169.254.0.
NAT Network Address Translation (NAT, also known as network masquerading or IP-masquerading) involves re-writing the source and/or destination addresses of IP packets as they pass through a router or firewall. Most systems using NAT do so in order to enable multiple hosts on a private network to access the Internet using a single public IP address. NAT is a non-standard protocol Global Local 192.168.1.1 192.168.1.2 192.168.1.3 192.168.1.0 10.1.2.3 Router/Gateway running NAT internet IP=10.1.2.3 192.
Default Gateway 192.168.1.1 192.168.1.2 192.168.1.3 192.168.1.0 10.1.2.3 Router/Gateway running NAT internet IP=10.1.2.3 192.168.1.4 192.168.1.5 Local Default Gateway is where packets addressed outside the subnet are sent to. Global Node 192.168.1.5 needs to send a packet to 207.68.172.246 (msn.com) Node 192.168.1.5 identifies that 207.68.172.246 is outside the subnet (255.255.255.0 ) The packet is sent to 192.168.1.0, the default gateway NAT translates the source field to 10.1.2.
Getting packets into a NAT network Local Default node gets all packets from internet from connection s not originated from subnet 192.168.1.1 192.168.1.2 192.168.1.3 Global 192.168.1.0 10.1.2.3 Router/Gateway running NAT internet IP=10.1.2.3 192.168.1.4 192.168.1.5 Default node is where all packets from internet that are not responses to packets from subnet are routed to. If the connection originates from the internet ( like connecting to a web server on an embedded device ) NAT has a default node.
TCP is One of the Protocols in the Internet Protocol Suite TCP - Transport Control Protocol TCP provides a “virtual” connection from one point to another. The protocol guarantees reliable and in-order delivery of sender to receiver data. TCP also distinguishes data for multiple, concurrent applications (e.g. web server and email server) running on the same host. TCP supports many of the Internet's most popular application protocols and resulting applications, including the world wide web, and email.
Other Protocols in the Internet Protocol Suite HTTP - HyperText Transport Protocol - Supported by Freescale Web Server • Used to transport HTML (web pages) POP3 - Post Office Protocol • Used to “pull” email from a server TFTP - Trivial File Transfer protocol - Supported by ColdFire Lite stack • Used to transfer blocks of data UDP - User Datagram Protocol - Supported via Interniche • Used to transfer data without a connection • Provides 65535 multiplexed ports per IP address PPP - Point to Point Protocol - S

USB Topology Introduction to USB Software TM General Concepts
Software – General Concepts In This Section: How Data is Transferred in USB TM How Does the Host Know the Device’s Requirements? The Enumeration Process: What happens when a device is connected? A More Detailed Look at What Comprises a Frame API Calls: What happens after enumeration?
How Data is Transferred in USB USB is a token-based (packet) standard. Data is transferred between the host and the device in a series of frames, transfers, transactions, and packets within1 Ms/1500 byte frames.
How Data is Transferred in USB Frames are made up of transfers, which are made up of transactions, which are made up of packets. The USB host schedules these 1mS frames when communicating with the low and full speed devices.
Software – General Concepts The General USB Process How Data is Transferred in USB Frame Transfer Transfer There are 4 types of data transfer: 1. Interrupt 2. Bulk 3. Isochronous 4. Control TM The type of transfer depends upon the type of device and its data requirements (this is discussed in more detail later).
Software – General Concepts The General USB Process How Data is Transferred in USB Transfer Transaction Transaction TM Each transfer can contain multiple transactions and a transaction can span multiple frames The host schedules transactions within the 1mS frame.
How Data is Transferred in USB Packet 3 Packet 2 Packet 3 Packet 2 Packet 1 Transaction Transaction Packet 1 Software – General Concepts The General USB Process TM For each transaction there are three types of packets that communicate the data between host and device: 1. Token Packet – the header that defines what follows 2. Optional Data Packet – contains the data being transmitted 3.
Software – General Concepts The General USB Process How Does the Host Know a Device’s Requirements? When a USB device is plugged into a USB port the host communicates with the device and configures each device according its unique requirements such as: 1. Type of transfer required (interrupt, bulk, isochronous, or control 2. Who supplies the power (host or device) 3. Maximum packet size 4. The number of configurations (e.g.
Software – General Concepts The General USB Process How Does the Host Know a Device’s Requirements? These requirements are communicated to the host through a hierarchy of C program descriptors. The types of descriptors include: TM 1. Device Descriptors 2. Configuration Descriptors 3. Interface Descriptors 4. Endpoint Descriptors 5.
Software – General Concepts The General USB Process How Does the Host Know a Device’s Requirements? This hierarchy of the most commonly used descriptors looks like this: Device Descriptor TM Configuration Descriptor Interface Descriptor Endpoint Descriptor Endpoint Descriptor Configuration Descriptor Interface Descriptor Endpoint Descriptor Endpoint Descriptor Interface Descriptor Endpoint Descriptor Endpoint Descriptor Interface Descriptor Endpoint Descriptor Endpoint Descriptor
Software – General Concepts The General USB Process How Does the Host Know a Device’s Requirements? Device Descriptor Since the device descriptor represents the entire device, there can be only one per device. This descriptor specifies basic information such as: USB version supported, maximum packet size, the number of configurations, and vendor and product ID info.
Software – General Concepts The General USB Process How Does the Host Know a Device’s Requirements? Configuration Descriptor The configuration descriptor is a header to the interface descriptors. It specifies how this configuration of the device is powered, what the maximum power consumption is, and how many interfaces there are. There can be more than one configuration descriptor (for example: if the device can switch between self-power and host-power).
Software – General Concepts The General USB Process How Does the Host Know a Device’s Requirements? Interface Descriptor The interface descriptor groups endpoints into functional groups that perform a single feature of the device.
Software – General Concepts The General USB Process How Does the Host Know a Device’s Requirements? Endpoint Descriptor The endpoint descriptors define what transfer type to use, the maximum packet size and time interval used to poll the frames (1mS for low or full speed devices and 125us for high speed devices). From this the host determines bandwidth requirements.

Software – General Concepts The General USB Process The Enumeration Process:What happens when a device is connected? 1. Enumeration -Upon powering up, the host: queries all connected devices to determine the requirements of each (such as, class of device power source, number and types of endpoints) and assigns a unique address for each. This same process occurs for devices that are dynamically “plugged in” to the host except the host waits ~120ms for the device to settle.
Software – General Concepts The General USB Process The Enumeration Process:What happens when a device is connected? Host What device class are you? Here is your unique address. Do you supply the power or do I? What transfer mode do you want? How many and of what type of endpoints do you need? TM Endpoints: A uniquely identifiable portion of a Universal Serial Bus device that is the source or sink of information in a communication flow between the host and device.

Software – General Concepts The General USB Process The Enumeration Process:What happens when a device is connected? 2. Transfer Mode - The host then determines which type of transfer each device requires. There are three transfer modes: Interrupt Transfer - Devices that send very little data such as mice or keyboards would choose this type of transfer.
Software – General Concepts The General USB Process The Enumeration Process:What happens when a device is connected? 3. As the host enumerates each device it sets aside bandwidth for the devices that use the interrupt and isochronous transfer modes and keeps track of the total bandwidth used. These two transfer modes can use up to 90% TM of the total bandwidth. 4.
The Enumeration Process:What happens when a device is connected? 5. The available bandwidth is then divided into frames, and the host controls those frames which contain 1,500 bytes. Every millisecond a new frame begins. Within the frame, slots are reserved for isochronous and interrupt devices (up to 90%) so that they are guaranteed the bandwidth they need. Bulk and control transfers use whatever space is left.

Software – General Concepts API Calls:What happens after enumeration? After enumeration the device is ready to perform the function it was designed for. It does so by issuing a set of properly sequenced API calls. TM Definition: Application Program Interface (API): A formalized set of firmware calls and routines that can be referenced by an application program to access driver functions.

USB Introduction On-the-Go: TM By 2001, there was a proliferation of peripheral devices that could be interconnected and pass data to each other. Because of this interaction of peripheral devices, the USB Group saw the need for a USB device to sometimes act as a device and sometimes act as the host.

OTG Device in Peripheral mode Same OTG Device in host mode TM Above is a typical applications that would use USB On-the-Go. On the left laptop is acting as the host controlling the flow of data to the camera phone and on the right the camera phone is acting as the host controlling the flow of data to the printer.
Appendix USB On-the-Go USBATopology Introduction to USB How does it work? USB On-the-Go: To implement OTG, two new protocols were added in the USB 2.0 addendum. These new protocols allow USB OTG host wake-up and role reversal respectively.
Appendix USB On-the-Go USBATopology to USB Initial declaration USB Introduction On-the-Go: When using A and B plugs, initially the device using the A plug is declared the host and the one using the B plug is declared the device. When using the mini-AB receptacle the ID plug pin declares the initial state of a device as host or device. State is then changed during host negotiations protocol by turning a pull-up resistor on and off.
Appendix USB On-the-Go USBATopology Introduction to USB Negotiation process USB On-the-Go: SRP (Session Request Protocol) Negotiations OTG-B (device) asks OTG-A (host) for a USB OTG session by signaling in one of two ways: TM •Pulsing an analog data line (D+ or D-), and •Pulsing VBUS through a relatively high impedance ( > 281 Ω) Note: The B-device pulses data line first and then pulses VBUS
Appendix USB On-the-Go USBATopology Introduction to USB Negotiation process USB On-the-Go: HNP (Host Negotiation Protocol): 1. OTG-A (host) enables OTG-B (device) to become host by sending SetFeature (b_hnp_enable) command to OTG-B (device). 2. OTG-A (host) suspends bus signaling so thatTM OTG-B (device) can now become host. 3. OTG-B (device) detects Suspend condition and turns off pull-up resistor. 4.
Appendix USB On-the-Go USBATopology Introduction to USB Negotiation process USB On-the-Go: Host Negotiation Protocol continued: 6. To return control back to OTG-A (host) , OTG-B (device) stops using bus and becomes peripheral/device. 7. TM OTG-A (host) sees lack of activity, disconnects and becomes host. Note: If the OTG-B (device) does not STALL the SetFeature(b_hnp_enable) command, the OTG-A (host) must give the OTG-B (device) an opportunity to become host before the OTG-A (host) may turn off VBUS.
