3.5 Using nonstandard connectors
RVI is supplied with cables that each terminate in a 20-way Insulation Displacement Connector
(IDC) connector, wired to the current ARM
®
JTAG connection standard. Box headers suitable
for this connector are fitted on all current ARM target hardware, and on several third-party
targets.
Some target hardware is fitted instead with a 14-way IDC box header:
• Older ARM target hardware uses the previous ARM JTAG connection standard (as used
by EmbeddedICE). This is signal-compatible with the current ARM standard. Use the
supplied adaptor card to connect to these targets.
• Some other targets instead use the Texas Instruments (TI) JTAG connection standard,
which has a different signal assignment to the ARM standards. This adaptor enables RVI
to connect to these targets, and is provided.
If you use the wrong 20-way to 14-way adaptor, you might damage the target hardware.
If you are not certain of the connection standard that your target hardware uses, you must check
the reference manual for the target before you connect it to the RVI run control unit. This is
especially important if you are using a target that has a 14-way IDC box header, or that is not
manufactured by ARM.
If the target that you are using does not use an ARM style connector, or if you are designing
target hardware, contact ARM for more information.
