1 USB-LAN EZ-EXTENDER INTERFACES This chapter provides the setup procedures for both the Blackfin USB-LAN EZ-Extender and EZ-KIT Lite (ADSP-BF533, ADSP-BF537 or ADSP-BF561) and describes each of the interfaces the extender supports. The information is presented in the following order. • “USB-LAN EZ-Extender Setup” on page 1-1 • “USB 2.
USB-LAN EZ-Extender Setup 3. Remove any rubber feet that may be attached to the EZ-KIT Lite. In place of these rubber feet, install the four nylon feet and screws provided with the USB-LAN EZ-Extender. Install the nylon feet in the mounting holes of the EZ-KIT Lite’s printed circuit board (PCB). Flip the EZ-KIT Lite upside down so that the three expansion headers (J1—3) are facing up. 4. Set the switches and jumpers on the USB-LAN EZ-Extender board.
USB-LAN EZ-Extender Interfaces Ethernet Software For information on the LAN software, refer to the LAN Software Readme.txt file located in the ...\VisualDSP++ install-path\Blackfin\Examples\USB-LAN EZ-EXTENDER \LAN directory. USB 2.0 Interface The USB-LAN EZ-Extender allows you to connect a USB 2.0 chip to a Blackfin processor without any other programmable logic required. PLX’s (formerly Netchip) Net2272 device ties directly to the asynchronous memory bank 3 of the Blackfin processor.
Ethernet Interface The USB IRQ line of the extender connects to PF10 on the ADSP-BF533/ADSP-BF561 processors and PF7 on the ADSP-BF537 processors. The flag pins can be used for push buttons or LEDs on the respective EZ-KIT Lites; consequently, the user must make the proper changes to that EZ-KIT Lite. When writing to and reading from the USB device using the EZ-KIT Lites, use memory addresses from Table 1-1. Table 1-1.
USB-LAN EZ-Extender Interfaces EZ-KIT Lites are described in the LAN file in the ...\Blackfin\Examples\USB-LAN EZ-EXTENDER\LAN subdirectory of the VisualDSP++ installation directory. The readme file describes the LAN software, source code, drivers, and explains how to run an Ethernet application. Software Readme.txt correct switch settings, refer to the schematics drawing of the L For respective device.
Optional ADSP-BF537 EZ-KIT Lite Interfaces The EZ-KIT Lite and extender must not be powered via the 7.5V supply when in Power-over-Ethernet (PoE) mode. A user can make the appropriate jumper changes to the EZ-KIT Lite and extender and then connect the kit to the extender to power both boards via the switch or Midspan device. The user must use a switch or Midspan device that supports power via the data pairs.

USB-LAN EZ-Extender Hardware Reference Jumper Settings Before using the Blackfin USB-LAN EZ-Extender, follow the steps in “USB-LAN EZ-Extender Setup” on page 1-1. Figure 2-2 shows the locations of all jumper headers. A two-pin jumper can be placed on the respective jumper header for different functionality. The following sections describe all possible jumper settings and associated functionality. Figure 2-2.
Jumper Settings Power Select Jumper (JP1) By default, the power select jumper, JP1, must have no jumpers on any of its pins. The jumpers can be used only when the extender is plugged into an ADSP-BF537 EZ-KIT Lite (see Table 2-1). Table 2-1. JP1 Settings Source of 5V Power JP1 Setting EZ-KIT Lite power No jumpers (default) USB test mode (do not use) JP1.1 and JP1.2 Power-over-Ethernet JP1.2 and JP1.3 When using an ADSP-BF533 or ADSP-BF561 EZ-KIT Lite, you must not place any jumpers on JP1.
USB-LAN EZ-Extender Hardware Reference LAN Power Jumper (JP2) The LAN power jumper, JP2, is used to power the SMSC’s 91C111 device with 3.3V (see Table 2-2). By default and in general, the jumper is plugged in for extra flexibility. You must make changes to JP2 only when no power is applied to the USB-LAN EZ-Extender and/or the EZ-KIT Lite. Table 2-2. JP2 Settings Functionality JP2 Setting No power to the LAN91C111 No jumper All other cases JP2.1 and JP2.
Switch Settings Switch Settings Before using the Blackfin USB-LAN EZ-Extender, follow the steps in “USB-LAN EZ-Extender Setup” on page 1-1. Figure 2-3 shows the locations of all switches. The following sections describe all possible switch settings and associated functionality. Figure 2-3. Switch Locations ADDR Enable Switch (SW1.1) The address enable switch, SW1.1, is used to control the output of the Blackfin address bus buffer (see Table 2-4). By default, the switch is set to ON . When SW1.
USB-LAN EZ-Extender Hardware Reference Ethernet processor. The address enable switch adds flexibility to the processors because you can turn the switch OFF when capacitive loading is an issue present with other peripherals on the EZ-KIT Lite. Table 2-4. SW1.1 Settings Functionality SW1.1 Setting Blackfin address buffer (U1) enabled ON (default) Blackfin address buffer (U1) disabled OFF FLAGS Enable Switch (SW1.2) The flags enable switch, SW1.
Switch Settings When SW1.3 is OFF, communication with the USB processor cannot be established. The SW1.3 adds flexibility to the extender—when the switch is OFF, the flag can be used for other peripherals of the EZ-KIT Lite. Table 2-6. SW1.3 Settings Functionality SW1.3 Setting USB IRQ enabled ON (default) USB IRQ disabled OFF Test Mode Enable Switch (SW1.4) The test mode enable switch, SW1.4, is an internal test pin and should not be used (see Table 2-7). By default SW1.4 is OFF. Table 2-7. SW1.
USB-LAN EZ-Extender Hardware Reference Table 2-8. SW2.1 Settings Functionality SW2.1 Setting Serial ROM disabled ON Serial ROM enabled OFF (default) IOS[2:0] Switch (SW2.2, SW2.3, SW2.4) The IOS[2:0] bits on the USB-LAN EZ-Extender are connected directly to the IOS[2:0] pins of the LAN91C111 Ethernet processor. By default, the switches are OFF. The IOS[2:0] pins are used in conjunction with the “Serial ROM Enable Switch (SW2.1)” to select between predefined EEPROM configurations.
