ADSP-21479 EZ-Board Evaluation System Manual

Using The ADSP-21479 EZ-Board
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 session based on a standalone debug agent
or an external emulator. To use the EZ-Board in multi-processor 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 platform based on the number of
JTAG devices in the JTAG chain using the Vi+ Configurator.
Then create a session in Vi+ based on the newly created plat-
form. For multiprocessor mode under CCES, create a platform based on
the number of JTAG devices in the JTAG chain using the Target Config-
urator. Then create a Debug Configuration in CCES based on the newly
created platform.
For a dual ADSP-21479 EZ-Board session, connect two EZ-Boards via
connectors
J3
and
P10
. Flip one of the two EZ-Boards by 180 degrees to
allow the boards to mate. To switch between single- and multi-processor
modes, use DIP switches
SW19–22
.
For more information, see “JTAG
Switches (SW19–22)” on page 2-16.
For three or more ADSP-21479 EZ-Board sessions, connect each of the
EZ-Board with JTAG cables. The cables connect JTAG pins of each
EZ-Board. By using the cables, you put the EZ-Board in a JTAG serial
chain. For three EZ-Boards, three JTAG cables are required. Similarly, for
four EZ-Boards, four JTAG cables are required. Note that each respective
EZ-board also requires its own power supply.
Part numbers for Samtec standard, off the shelf link port cables can be
found in
“MP JTAG Out Connector (P10)” on page 2-29
