MB1: Microboot 1. [More…]
MB1 is the first boot loader to run after the boot ROM. Its major tasks are to:
Initialize the SDRAM based on MB1 boot configuration table (MB1-BCT)
Load the firmware that initializes the CPU complex
Set the security settings
Configure pinmux/GPIO for the SoC
Program the PMIC for the VDD_CPU and VDD_DDR rails
Load the next stage boot loader (MB2)
MB1 runs on the BPMP. It is considered an extended boot ROM because the security level of MB1 is the same as boot ROM.
