1.2 After Reset

On the rising edge of RESETn, the following steps will occur:

  1. The boot pins will be latched.
    Note:

    This only occurs when coming out of a POR, as the boot pins will not be relatched after a warm reset.

  2. The boot master core (1) begins execution of the ROM bootloader.
    1. The ROM bootloader reads from the boot medium and begins sequentially executing the AIS commands in the boot image 2(2).
    2. The last AIS command will jump to the entry point of the executable.
1. For OMAPL138 and AM1808, ARM9 is is the boot master core. For C6748, C674x core is the boot master core.
2. For non-AIS boot modes such as NOR legacy, or NOR direct, the process is different. For details on these boot modes, see Using the OMAP-L132/L138 Bootloader.
