JTAG Interface
The EZ-KIT Lite design enables a multi-processor JTAG session using
connectors
and
P8
mode. In single-processor mode, create a CCES session based on a stand-
alone debug agent or an external emulator. To use the EZ-KIT Lite in
multi-processor mode, install an external emulator. Only one external
emulator is required for the main EZ-KIT Lite; other EZ-KIT Lites in the
JTAG chain do not require an emulator. In this mode, create a CCES
platform based on the number of JTAG devices in the JTAG chain using
the CCES Target Configurator. Then create a session for the EZ-KIT Lite
based on the newly created platform.
For a dual ADSP-BF609 EZ-KIT Lite session, connect two EZ-KIT Lites

For three or more ADSP-BF609 EZ-KIT Lite sessions, connect each of
the boards with JTAG cables. The cables connect JTAG pins of each
board and put the EZ-KIT Lites in a JTAG serial chain. For three EZ-KIT
Lites, three JTAG cables are required. Similarly, for four EZ-KIT Lites,
four JTAG cables are required. Note that each respective EZ-KIT Lite
board also requires its own power supply.
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
