Using the IOMUX Design Aid

Update Conflicts This item cannot be enabled unless the Auto-Detect option is unselected.
Selecting “Update Conflicts” manually forces the design’s assignments to be
checked. Usually this option is used for very large designs with many signals to
speed up the selection.
4.5.2.4 Help Menu
Figure 4-16 provides a partial view of the application window, showing the expanded options for the help
menu. This menu contains a single item, which displays information about the IOMUX application.

4.5.3 Search Box
The search box performs a simple textual search for full or partial signal names or package ball/pin IDs.
Note that the text search is a basic string search. It is not case sensitive nor does it have options for refining
the search criteria. Search hits are highlighted in green in the signal selection pane.
4.5.4 Signal Selection Pane
Once an i.MX device is selected, the signal selection pane is populated with all IOMUX options for that
device and package combination. The signal selection pane is then used to assign signals and identify
signal assignment conflicts.
By default, all signals are initially unassigned. Signals are assigned by clicking in the check box next to a
peripheral group or, when expanded, an individual signal. For information about identifying and resolving
conflicts, see the walkthrough in Section 4.2.1, “Identifying Signal Conflicts with the Signal Selection
Pane.”
4.5.5 Signal Assignments and Ball Map Pane
The signal assignments and ball map pane allows the user to view either a textual summary of information
or the ball map graphical display. Users select the options by choosing either the signals tab or the ball
diagram tab.
4.5.5.1 Signals Tab
The signals tab contains the list of all currently assigned signals in the current design. This tab is selected
by default and can also be selected by clicking in the signals tab if the alternate ball diagram tab is
displayed.
