Default Configuration connector locations, and LEDs used in installation. Confirm that your board is in the default configuration before using the board. Figure 1-1.
Using ADSP-21479 EZ-Board EZ-Board Installation For correct operation, install the software in the order presented in the VisualDSP++ Installation Quick Reference Card. Substitute instructions in step 3 with instructions in this section. There are two options to connect the EZ-Board hardware to a personal computer (PC) running VisualDSP++ 5.0: via an Analog Devices emulator or via a standalone debug agent module. The standalone debug agent allows a debug agent to interface to the ADSP-21479 EZ-Board.
EZ-Board Session Startup EZ-Board Session Startup 1. If you are running VisualDSP++ for the first time, navigate to the VisualDSP++ environment via the Start–>Programs menu. The main window appears. Note that VisualDSP++ is not connected to any session. Skip the rest of this step to step 2. If you have run VisualDSP++ previously, the last opened session appears on the screen.
Using ADSP-21479 EZ-Board Specify your own Session name for the session or accept the default name. The session name can be a string of any length; although, the box displays approximately 32 characters. The session name can include space characters. If you do not specify a session name, VisualDSP++ creates a session name by combining the name of the selected platform with the selected processor. The only way to change a session name later is to delete the session and open a new session. Click Next. 6.
Evaluation License Restrictions Evaluation License Restrictions The ADSP-21479 EZ-Board installation is part of the VisualDSP++ 5.0 update 8. The EZ-Board is a licensed product that offers an unrestricted evaluation license for the first 90 days. Once the initial unrestricted 90-day evaluation license expires: • VisualDSP++ restricts a connection to the ADSP-21479 EZ-Board via the USB port of the standalone debug agent interface only. Connections to simulators and emulation products are no longer allowed.
Using ADSP-21479 EZ-Board mation about a specific memory type, go to the respective section in this chapter. Table 1-1.
SDRAM Interface SDRAM Interface The ADSP-21479 processor connects to a 32 MB Micron MT48LC16M16A2P-6A chip through the SDRAM controller. The SDRAM memory controller on the processor and SDRAM memory chip are powered by the on-board 3.3V regulator. The SDRAM controller and memory on the EZ-Board can operate at a maximum clock frequency of 133 MHz.
Using ADSP-21479 EZ-Board mation on how to initialize the registers after a reset, search the VisualDSP++ online Help for “reset values”. Parallel Flash Memory Interface The parallel flash memory interface of the ADSP-21479 EZ-Board contains a 4 MB (4M x 8 bits) Numonyx M29W320EB chip. Flash memory is connected to the 8-bit data bus and address lines 0 through 21. Chip enable is decoded by the MS1 select line (default) through switch SW13 position 2. See “External Port Enable Switch (SW13)” on page 2-12.
Watch Dog Timer Interface The SPI flash memory, a 16 Mb ST M25P16 device, connects to the SPI port of the processor and designates: • DPI pin 5 (DPI_P5) as a chip select • DPI pin 3 (DPI_P3) as the SPI clock • DPI pin 1 (DPI_P1) as the master out slave in (MOSI) pin • DPI pin 2 (DPI_P2) as the master in slave out (MISO) pin The same SPI port and DPI pins are connected to the serial flash memory and audio codec via switch SW3. See “DPI [1–8] Enable Switch (SW3)” on page 2-9.
Using ADSP-21479 EZ-Board Be default, the watch timer interface is turned off. In order to use the feature, a user needs to turn switch SW13 position 8 ON. SW13 connects the watch dog reset out pin to the ADM708 system reset circuit. See “External Port Enable Switch (SW13)” on page 2-12. Special attention must be paid to this function because it can cause the processor and EZ-Board to remain in a permanent reset.
Shift Register Interface Example programs are included in the EZ-Board installation directory to demonstrate RTC functionality. Shift Register Interface The shift register (SR) of the ADSP-21479 processor can be used as a serial to parallel data converter. The shift register module consists of an 18-stage serial shift register, 18-bit latch, and three-state output buffers. The shift register and latch have separate clocks.
Using ADSP-21479 EZ-Board Access to the shift register of the processor is available via the shift register interface connector (P4). Users can use a standard 2 mm ribbon cable if they require off-board capabilities. For more information, see “Shift Register Interface Connector (P4)” on page 2-27. S/PDIF Interface The ADSP-21479 processor has a built-in S/PDIF transmitter and receiver for digital audio applications.
Audio Interface for audio in and out. To use the differential connectors, change DIP switches SW15–18. A standard, off the shelf DB25 connector to XLR cables is required to operate in this mode. For more information, see “Audio In1 Left Selection Switch (SW15)” on page 2-14 through “Audio In2 Left Selection Switch (SW18)” on page 2-16, and “ADSP-21479 EZ-Board Schematic” on page B-1. The processor interfaces with the codec via DAI and DPI pins.
Using ADSP-21479 EZ-Board serial ports. Connecting the codec in this manner enables a flexible audio sample rate and allows the processor to run at the maximum core frequency. The audio interface also has a 3.5 mm connector (J8) for headphones. The headphones share the output with the external DAC5 and DAC6 circuits of the analog audio interface. Switch SW23 must be enabled for the headphones. A volume control potentiometer (R493) is used to increase or decrease the headphone’s volume.
LEDs and Push Buttons • DPI pin 11 (DPI_P11) as UART_RTS • DPI pin 12 (DPI_P12) as UART_CTS Example programs are included in the EZ-Board installation directory to demonstrate UART and RS-232 operations. For more information about the UART interface, refer to the ADSP-214xx SHARC Processor Hardware Reference. LEDs and Push Buttons The EZ-Board has eight general-purpose user LEDs connected directly to the processor, one EZ-Board power LED, and one board reset LED.
Using ADSP-21479 EZ-Board Two general-purpose push buttons are attached to the flag pins of the processor, while the other two are attached to the DAI pins. All of the push buttons and LEDs are connected to the processor through DIP switches. The DIP switches can disconnect the processor pins, which in turn are connected to the push buttons and LEDs. See the respective switch section in “ADSP-21479 EZ-Board Hardware Reference” on page 2-1.
JTAG Interface lator is connected to P1 on the back side of the board. See “EZ-Board Installation” on page 1-5 for more information. The ADSP-21479 EZ-Board can be set up as a single- or multi-processor system. By default, the board is set up in single-processor mode. In single-processor mode, create a VisualDSP++ session based on a standalone debug agent or an external emulator. To use the EZ-Board in multi-processor mode, install an external emulator.
Using ADSP-21479 EZ-Board Expansion Interface II The expansion interface II allows an Analog Devices EZ-Extender or a custom-design daughter board to be tested across various hardware platforms with identical expansion interfaces. The expansion interface II implemented on the ADSP-21479 EZ-Board consists of two connectors: a 0.1 in. shrouded header (P2) and a Samtec QMS series header (J1). The connectors contain a majority of the ADSP-21479 processor’s signals.
Power-On-Self Test VDDRTC, VDDEXT, and VDDINT voltage domains. The associated jumper on connectors P3, P6, or P7 must be removed to measure current draw. Once the jumper is removed, voltage across the resistor can be measured using an oscilloscope. Once voltage is measured, current can be calculated by dividing voltage by 0.05. For the highest accuracy, a differential probe should be used for measuring voltage across the resistor.
Using ADSP-21479 EZ-Board Background Telemetry Channel The USB debug agent supports the background telemetry channel (BTC), which facilitates data exchange between VisualDSP++ and the processor without interrupting processor execution. The BTC allows you to read and write data in real time while the processor continues to execute. For increased performance of the BTC, including faster reading and writing, please check our latest line of processor emulators at: http://www.analog.

Jumpers Flash WP Jumper (JP1) The flash WP jumper (JP1) write-protects block 0 of the parallel flash chip. Block 0 is located at address range 0x0400 0000–0x0400 1FFF. The POST begins at block 0 and continues on to other blocks in flash memory. When the jumper is installed on JP1, and the parallel flash driver from Analog Devices is used, block 0 is read-only. By default, JP1 is not installed. S/PDIF Loopback Jumper (JP2) The S/PDIF loop back jumper ( JP2) is used for internal testing only.
