8.1 Single Stage Boot Examples

Single stage boot examples demonstrate booting the K2 devices directly from the boot media specified by the boot mode pins using the default settings specified by the boot parameter loaded by the BootROM. For default boot parameter settings used by the bootROM, see the device-specific data manual. The sample application is designed to wake up the secondary Arm core upon boot and then initializes the UART to print message when each core wakes up. Each Arm core will send a message over UART: "Core n standing by..." where n is the Arm core number.
