Boot Mode Configuration
5 Boot Mode Configuration
This section provides information on boot mode configuration pins allocation and boot devices interfaces
allocation.
5.1 Boot Mode Configuration Pins
Table 93 provides boot options, functionality, fuse values, and associated pins. Several input pins are also
sampled at reset and can be used to override fuse values, depending on the value of BT_FUSE_SEL fuse.
The boot option pins are in effect when BT_FUSE_SEL fuse is ‘0’ (cleared, which is the case for an
unblown fuse). For detailed boot mode options configured by the boot mode pins, see the i.MX
6Dual/6Quad Fuse Map document and the System Boot chapter of the i.MX 6Dual/6Quad reference
manual (IMX6DQRM).
