Using the IOMUX Design Aid
This chapter explains how to use of the IOMUX system design aid (IOMux.exe), which facilitates the
assignment of internal signals to external device balls/pins. The IOMUX design aid performs the following
functions:
• Makes signal assignments for the supported i.MX device
• Identifies conflicts, allowing them to be resolved in real-time
• Allows notes or comments for each signal to be added to the list of assignments
Design configurations can be saved for future use and exported for use in schematics or software source
code as supplementary documentation of a system.
