Blackfin/SHARC USB EZ-Extender Manual 1-1 1 BLACKFIN/SHARC USB EZ-EXTENDER INTERFACES This chapter provides the setup procedures for both the Blackfin/SHARC USB EZ-Extender and EZ-Board (ADSP-BF518F, ADSP-BF526, or ADSP-21469) and describes the interfaces the extender supports. The information is presented in the following order. “Blackfin/SHARC USB EZ-Extender Setup” on page 1-1 “USB 2.0 Interface” on page 1-2 Blackfin/SHARC USB EZ-Extender Setup It is very important to set up all components of the system containing the Blackfin/SHARC USB EZ-Extender, then apply power to the system. The following procedure is recommended for correct setup. Power your system after these steps are completed: 1. Read the applicable design interface section in this chapter—the text provides an overview of the interface capabilities. 2. Read “System Architecture” on page 2-2 to understand physical connections of the extender board. For detailed information, refer to “Blackfin/SHARC USB EZ-Extender Schematic” on page B-1. 3. Set the jumpers on the Blackfin/SHARC USB EZ-Extender board. Use the block diagram in Figure 2-1 on page 2-2 in conjunction with “Jumper Settings” on page 2-2.
USB 2.0 Interface 1-2 Blackfin/SHARC USB EZ-Extender Manual4. Set the switches and jumpers on the EZ-Board. If not already, familiarize yourself with the EZ-Board documentation and sche- matic drawings (see “Product Information”). Compare the expansion interface signals of the Blackfin/SHARC USB EZ-Extender board with the EZ-Board signals to ensure there is no contention. For example, it may be necessary to disable other devices connected to the expansion interface of the processor and disable peripherals on the EZ-Board. 5. Install the Blackfin/SHARC USB EZ-Extender on the EZ-Board via the high speed expansion interface. USB Software For information about USB software, refer to the readme text files in the Examples folder of the installation directory. USB 2.0 Interface The Blackfin/SHARC USB EZ-Extender enables a connection between a USB 2.0 chip and Blackfin/SHARC processor without any other pro- grammable logic. The PLX Technology’s NET2272 controller ties directly to the asynchronous memory bus of the Blackfin or SHARC processor. You can read from and write to the USB 2.0 controller by addressing the named memory bank directly. You can reset the NET2272 controller by asserting LOW one of the four GPIO signals of the expansion interface. Refer to the appropriate EZ-Board manual to learn how the GPIO signals connect to the processor. The USB IRQ signal of the NET2272 controller connects to one of the four GPIO signals on the expansion interface. Refer to the appropriate
Blackfin/SHARC USB EZ-Extender Manual 1-3 Blackfin/SHARC USB EZ-Extender Interfaces EZ-Board document to learn how the GPIO signals connect to the processor. The USB CS signal of the NET2272 controller connects to one of the four AMS signals on the expansion interface. Refer to the appropriate EZ-Board manual to learn how the AMS signals connect to the processor. The jumper settings required for each of the respective EZ-Boards are described in the readme text files in the Examples folder of the installation directory. The readme file describes the USB software, source code, driv- ers, and explains how to run a USB-based application.
