ADSP-21489 EZ-Board Hardware Reference
The default configuration applies to either a debug agent or an external
emulator, such as the Analog Devices high-performance USB-based emu-
lator (HP-USB ICE for short). To use an external emulator and multiple
EZ-Boards simultaneously in one VisualDSP++ multi-processor session,
set up the boards as shown in Table 2-17 . Attach the boards to each other
via connectors J3 and P12 . For two EZ-Boards, no external cables are
required. For three or more EZ-Boards, obtain Samtec JTAG cables
described in “MP JTAG Connector (J3)” on page 2-25 and “MP JTAG
Out Connector (P12)” on page 2-28 .
