You might want to link several groups to a single connection if the groups represent different, possibly optional, parts of the same development platform. For example, the Integrator/AP motherboard definition BOARD=AP and an Integrator core module definition such as BOARD=CM7TDMI. This kind of layout is shown in tree form in Figure 4.3.

When you reference multiple boards, RealView Debugger merges the settings from each matching group. Therefore the complete configuration is the combined configurations of all of the matching groups. If the same setting is specified in more than one group, the specification in the group that is listed first in the Debug Configuration is used, for example BoardChip_name=AP in Figure 4.3.
