2.1.3. Target hardware requirements

RealView ICE has the following target hardware requirements:

A device interface conforming to the IEEE Std. 1149.1-2001 (JTAG) specification.
Electronic signals available to the interface, and within the limits of current and voltage specified in Chapter 9 System Design Guidelines.
One of the following IDC box headers on the target hardware:
- a 20-way header that conforms to the current ARM JTAG connection standard (as described in Appendix A JTAG Interface Connections)
- a 14-way header that conforms to the previous ARM JTAG connection standard (as used by the ARM EmbeddedICE^® run control unit).
To use any other connectors, you must construct an appropriate adaptor or cable yourself.
A maximum cable length between the target hardware and the RealView ICE run control unit of:
- 30cm if you are using a 20-way ribbon cable
- 3m if you are using a 40-way ribbon cable with the supplied LVDS probe.
Otherwise, one or more of the modifications described in Chapter 9 System Design Guidelines must be used.
One or more ARM architecture CPUs that has supporting debug logic linked into a scan chain. This includes most ARM7™, ARM9™, ARM10™, and ARM11™ cores. It does not include the StrongARM^® and XScale processors.

You can use the RealView Update application to find out which processors are supported by the version of RealView ICE that you are using. To do this, start the RealView ICE Update application (see Chapter 7 Managing the RealView ICE Software) and select Version Info... from the RVI menu.
