Boot Modes
12.1 Overview
The i.MX28 boot process begins at Power On Reset (POR) where the hardware reset logic
forces the ARM core to begin execution starting from the on-chip boot ROM. The boot
ROM logic reads hardware inputs such as the boot pins on the IC or OCOTP bits to determine
the boot flow behavior of the i.MX28.
The main features of the ROM include:
The i.MX28 boot ROM supports the following boot devices:
Secure Boot
A key feature of the i.MX28 ROM is the ability to perform a secure boot. This is supported
by
These are independent features and are not dependent on each other.
The encrypted boot feature is an inherent element of the SB boot format used by the i.MX28
ROM. The encrypted boot feature is easily enabled through the use of tools provided by
Freescale to provide image confidentiality..
