ADSP-21489 EZ-Board Evaluation System Manual 1-19
Using ADSP-21489 EZ-Board
An example program is included in the ADSP-21489 installation directory
to demonstrate functionality of the LEDs and push buttons.
JTAG Interface
The JTAG connector (P1) allows the standalone debug agent module to
connect a VisualDSP++ debug session to the ADSP-21489 processor. The
debug agent operates only when the external 5V wall adaptor (P16) is
used.
The standalone debug agent can be replaced by an external emulator, such
as the Analog Devices high-performance USB-based emulator. Be careful
not to damage the connectors when removing the debug agent. The emu-
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-21489 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 sin-
gle-processor mode, create a VisualDSP++ session based on a standalone
debug agent or an external emulator. To use the EZ-Board in multi-pro-
cessor mode, install an external emulator. Only one external emulator is
required for the main EZ-Board; other EZ-Boards in the JTAG chain do
not require an emulator. In this mode, create a VisualDSP++ platform
based on the number of JTAG devices in the JTAG chain using the Visu-
alDSP++ Configurator. Then create a session in VisualDSP++ based on
the newly created platform.
