6.1 EmbeddedICE Interface
A debuggable ARM processor (such as ARM7TDMI) on the ARM Development Board can
be controlled through its JTAG port using the EmbeddedICE interface.
The EmbeddedICE interface is packaged separately from the ARM Development Board.
The host computer requires the ARM Software Development Toolkit to communicate with the
EmbeddedICE interface: the
ARM Software Development Toolkit Reference Manual
(
ARM
DUI 0020
) explains how to use the tools with the EmbeddedICE interface.
This chapter describes the physical connection between the EmbeddedICE interface and
the ARM Development Board. For details on how to connect the system components
together refer to the
Target Development System User Guide (ARM DUI 0061)
.
If you have the Angel Debug Monitor resident in the on-board FLASH then you do not need
to use the EmbeddedICE interface.
6.1.1 EmbeddedICE interface connector
The interface connector PL1 (shown below), is mounted on the header card. It is a 14-way
box header as shown in
Figure 6-1: EmbeddedICE interface connector PL1 (viewed
from above)
below.
This plug is connected to the EmbeddedICE interface module using a short 14-way IDC
cable with IDC sockets at each end.
Note
The signals on this interface are at 3.3V, so care should be taken if the JTAG port is
connected to any 5V system.
