To enable semihosting you must set the variable semihost_enabled, shownin Figure 6-7 on page 6-13 and Figure 6-9 on page 6-16:• Standard semihosting is enabled by default, and is the only mode available onRealView ICE. The behavior of semihosting depends on your target core, andyour target vehicle (see Standard semihosting behavior on page 6-16)• DCC semihosting is available on Multi-ICE (see DCC semihosting on page 6-17).ARM DUI 0153G Copyright © 2002-2005 ARM Limited.
